===Royal Small Arms Factory L1A1 SLR===
==L1A1==
Funco's elder sister Fal is based off the FN FAL, more specifically the [[FN FAL#L1A1|British L1A1 SLR]] variant. She is described as being beautiful and smart. Fal appears in "Grip and Hold!". The rifle appears in "Wash and Scrub!" when Fal explains the origin of the L1A1. Even if Fal is depicted as being based on the British L1A1 model (so semi-automatic only), while confronting her younger sister at the fountain in "Go for it! Pass it!" she is seen firing a burst in fully automatic fire, much like the original Belgian model. This is apparently a reference to a field-modification that Australian troops did to their L1A1s during the Vietnam War to lock their weapons in full-auto.
Funco's elder sister '''Fal''' is the British [[L1A1]], often listed as "FAL L1A1" in the anime/manga, likely for clarity. Beautiful, smart, and an excellent tactician, Fal embodies all the traits of an admirable older sister. In the show as it aired Fal is at one point seen firing a burst of full-auto, something the semi-auto-only L1A1 is not capable of. This was corrected to three rapid shots in semi-auto for the BD release.

==Fabrique National FAL==
==C1A1==
An [[FN FAL]] appears in "Wash and Scrub!" when the narrator explains to the audience how the L85 was created.
A C1A1 is shown during the history of the L85. The Japanese text simply reads "early version FAL" and gives a cartridge listing of [[Sturmgewehr 44|7.92x33mm Kurz]], which seems to be mixing up two FAL variants that independently are both very relevant to the topic. Canada was the first country to adopt the FAL, with the Canadians being responsible for converting its specifications from metric to imperial, thus creating the "inch-pattern" FAL. The British L1A1 (''Upotte!!'''s Fal) and Australian L1A1 were both derived from the Canadian C1A1. The C1 has several features quite distinct from other FAL variants (including its Commonwealth siblings), most notably an open-topped receiver with a stripper clip guide as well as a different rear sight.
The mention of 7.92x33 Kurz is a reference to the FN Universal Carbine, the very first prototype of what would become the [[FAL]]. Developed almost immediately after WWII, the Universal Carbine would quickly evolve into the FN Automatic Carbine in .280 British, before the American insistence on adopting 7.62x51mm as the new NATO standard forced FN to adapt their rifle for that cartridge.
[[File:Upotte early FAL.jpg|thumb|none|600px|The first FN FAL as depicted. The carry handles appears to be folded down. The plastic parts (buttstock, foregrip and pistol grip) were changed to wood. Also note that the caliber listed was only used in the prototype FAL, not the production model]]

Revision as of 07:46, 21 November 2022
Work In Progress
This article is still under construction. It may contain factual errors. See Talk:Upotte!! for current discussions. Content is subject to change.
Upotte!! is a slice-of-life and action series whose characters are the personifications of firearms. Upotte!! goes to great lengths to showcase many technical details and historical trivia on the subject, often through the use of cut-in narrated demonstrations to help explain the plot point (or joke) in a given scene. The story begins with a human teacher being transferred to Seishou Academy, entirely oblivious to its purpose as a school for personified firearms. The students are divided by weapon class, with submachine guns being in elementary school, assault rifles and shotguns in middle school, and battle rifles and sniper rifles in high school; most of the faculty are also guns. The main cast features Funco (FNC), Ichiroku (M16A4), Sig (SG 550), and Elle (L85A1), and their many adventures and misadventures.
The following weapons were used in the anime series Upotte!!:
A Glock 26 is seen during a narrated explanation of red dot sights.
Walther PPK
A Walther PPK is shown in a narrated explanation of the importance of weight.
unidentified pistol
A poster for what is presumably an in-universe spy film is seen in Ichiroku and Elle's room, featuring a pistol of some sort.
Submachine Guns
Fabrique Nationale P90 TR
An FN P90 TR is seen on a gun rack during a cut-in when Sig bluntly states that she thought the reason Ichiroku was popular was because she's cheap. Interestingly, the P90 is fitted with an adapter to take STANAG magazines, something only compatible with airsoft P90s.
Heckler & Koch MP5A2
A Heckler & Koch MP5A2 is seen in the hands of MP, the personification of said SMG. As with all the characters, the full designation is her "full" name ("MP5A2") but she goes by a shorter, more conversational name in virtually all circumstances. MP is one of G3's many younger sisters, as the MP5 is essentially a G3 scaled down to a submachine gun. Due to this, Sig nicknames her Chii3 ("Small3").
Ingram M-10
An Ingram M-10 is seen in the background when MP explains why M-10 suddenly stopped talking, due to her having an extremely high rate of fire (1090 rounds per minute is mentioned). M-10, who also goes by Ram (from "Ingram"), had been explaining why Gossan ("five-three") is grouped with the SMGs despite using rifle-calibre ammo, as she's the personification of the HK53 (an MP5-sized HK33).
M1928 Thompson
An M1928 Thompson with a drum magazine is held by its personification, Thompson, on the cover of the first volume of Rufuira!!, a doujinshi by the manga's artist; this manga makes a cameo lying on the floor of the human teacher's room. The human teacher's name is never given during the show, and most characters simply refer to him as Genkoku, essentially "Modern Literature (teacher)".
MP 40
An MP 40 is shown during the overview of the history of submachine guns. The narrator also makes reference to the WWI-era MP 18 during this sequence.
Shotguns
Remington Model 870
A Remington Model 870 is used to demonstrate the difference between a traditional pump-action shotgun with a non-detachable tube magazine, and a self-loading shotgun with detachable box magazines, in this case the Saiga-12. A chibi-form Ichiroku is seen firing one at a chibi Elle, who is portraying a rabbit.
Izhmash Saiga-12K
As mentioned above, Saiga is the personification of the Saiga-12K shotgun. Together with the rest of the Eastern Bloc firearms she attends Akaganekou ("Red Steel High"). Saiga ambushes Ichiroku and Sig during the battle of Atami, and continues to hold a stalemate with copious amounts of buckshot throughout the battle.
Assault Rifles & Light Machine Guns
AK-47
Two different AK-47 patterns are seen as the narrator (who uses the Russian term Avtomat Kalashnikova) explains the rivalry between the M16 and AK during the Vietnam War, and the reputations both guns earned during that conflict. The first one seen is a final production "Type 3" pattern, the other is an early-pattern "Type 1". It should be noted that the "Type 1/2/3" descriptors are terms created by Western historians to help categorize the three patterns of AK-47, rather than being official Russian terminology.
RPK
An RPK light machine gun is used by RPK. Tall, well-built, and always eager for a good fight, RPK makes for a stellar personification of her firearm. Although generally rather trigger happy, RPK also makes use of her rifle's long barrel and bipod to provide some very impressive long-range precision support at the beginning of the battle of Atami.
AK-74
The leader of the Akaganekou group that instigates the battle of Atami is Nanayon ("seven-four"), personification of the AK-74. Most of the Akaganekou "extras" are also armed with AK-74s, though they should be canonically considered to be using different, similar Eastern Bloc weapons.
AKS-74U
After Sig's impractical-but-awesome one-handed shooting demonstration, Funco and Sig attempt to persuade Genkoku of its usefulness by claiming it could be used to write messages on the walls of an enemy camp some distance away. The "camp" in question is clearly set somewhere in the Middle East, and two of the three fighters there are armed with rifles. Given the setting/theme these are most likely Kalashnikov-pattern rifles, and the one with a visible muzzle appears to best match the AKS-74U.
Bushmaster ACR
A poster showcasing a disassembled Bushmaster ACR is seen in Curly's shop. The rifle is fitted with a non-standard stock (its proper stock is seen elsewhere on the poster) as well as some other parts on the poster not being for the ACR, such as the GL1 grenade launcher for the F2000. This seems to be explained by the Japanese text describing custom parts and fitment work.
CETME Modelo L
A CETME Modelo L is used by Modelo, seen in the jungle tournament. One is also featured on the sign for Curly's gun shop, as well as on a rack in the shop itself.
CIS SR 88A
An SR 88A, manufactured by CIS (now ST Kinetics), appears in the hands of Hachihachi ("eight-eight"), and another is seen in Curly's shop.
ST Kinetics SAR 21
A ST Kinetics SAR 21 is used by Sar. Like Aug, she wears glasses presumably to represent the SAR 21's built-in optic. One is also seen in Curly's shop.
Daewoo K2
Shortly after arriving at Seishou Academy, Headmaster Springfield takes Genkoku on a tour of the school, including its firing range. In addition to the named characters present, five "extras" are seen in the background as well, four of whom have rifles that are just barely seen well enough to be identified. One of them appears to be a Daewoo K2.
Enfield EM-2
An Enfield EM-2 is shown during the explanation of the history of the L85. The narrator opens by mentioning that the British started work on intermediate cartridges and bullpup rifles in the 1940s, while certain relevant cartridges from the era appear on screen, including .276 Pedersen, 6.5x52mm Carcano, and 6.5x50mmSR Arisaka. The EM-2 ultimately was adopted by the British military... but that decision was almost instantly overturned by a new incoming government, under pressure from the Americans who were insisting on adopting 7.62x51mm as the new NATO standard. As a result, the British ultimately adopted the inch-pattern FAL as the L1.
Enfield XL64E5
The Enfield XL64E5 is briefly seen near the end of the L85 history cut-in, shown just before the L85 itself is revealed.
Enfield L85A1
Elle, from the "L" in her name, is the personification of the L85A1. She is specifically the L85A1 and not the much-improved L85A2, and as such suffers from constant breakages and unreliability, having a generally quiet demeanour, though she always tries her best. Elle is also Ichiroku's roommate.
Enfield L85A2
The L85A2 appears near the end of the history of the the L85. The improvements having been done by Heckler & Koch is also specifically mentioned.
Colt Canada L119A1
A Colt Canada L119A1 is seen in the hands of a Special Air Service soldier during an overview of the history of the L85 and its various problems, noting that the SAS opted to adopt an M16-based rifle instead. The Canadian C8 is essentially a development of the Colt Model 653, with the C8A1 introducing a flattop upper, and the later C8SFW featuring a slightly longer heavy barrel. The C8SFW was adopted by the British as the L119A1, and the one seen here is equipped with an EOTech holographic sight and magnifier.
FARA 83
The FARA 83 makes its media debut in the hands of Fara, seen during the jungle tournament. The FARA 83 notably doesn't appear in Curly's shop, the position on the gun rack it was likely intended to occupy instead featuring a custom M16.
Fabrique Nationale FNC
Funco is the personification of the FN FNC, and main protagonist of the series. Meeting Genkoku by chance during a festival, through an honest accident he discovers that she wears a thong, a trait shared by all personifications of rifles with (folding) skeleton stocks. Forgetting her actual name, he lets "girl with the thong" slip out a few times, usually ending up in the hospital as a result. Funco's FNC notably lacks a bayonet lug, a feature usually associated with the semi-auto civilian model, though she is otherwise in line with the standard original-production military pattern. That the FNC was directly responsible for the Belgian SS109 cartridge being adopted as 5.56mm NATO is a fact noted in the show. A replica (presumably airsoft) FNC appears during the climactic battle, serving as a distraction.
The FNC's predecessor and Funco's direct older sister, the CAL, is also mentioned, though neither she nor her rifle are actually seen; Cal is Sig's roommate.
GIAT FA-MAS G1
A FA-MAS G1 is seen alongside an AUG during the history of the L85, listing both as examples of bullpup rifle designs adopted before the L85. The show uses the less common but more technically correct spelling of "FA-MAS", with the dash separating "Fusil d’Assaut" from "Manufacture d’Armes de Saint-Étienne"; this is how the rifle's markings are actually written. Another FA-MAS is seen in the hands of a Seishou student at the firing range, though she is not the canonical Upotte!! FA-MAS who appears in the manga after the events of the anime. The canon Famas has long reddish-blond "drill"-style hair, does not attend Seishou, and is the F1 variant.
Heckler & Koch HK33E
A Heckler & Koch HK33E is used by HK33E, who unlike basically everyone else goes by her full designation rather than a nickname. Being the oft-forgotten middle child between the G3 and MP5, HK33E has a fairly strong inferiority complex, which likely contributes to her dislike of nicknames. Despite this, or rather because of this, Sig nicknames her Chuu3 ("Mid3") much to her annoyance. Ichihachi later nicknames her Mimi, an alternate reading of the two threes in her designation; she is less averse to this name, and the two eventually become friends.
Heckler & Koch G36V
A Heckler & Koch G36V, identifiable by its lack of dual optics, is seen in Curly's shop.
Heckler & Koch HK416
One of the Seishou students at the range has what appears to be a Heckler & Koch HK416. The rifle of the student between HK416 and K2, who is entirely hidden behind Genkoku, has its barrel just barely visible above the HK416's buffer tube, and it can be seen recoiling when firing along with a puff of muzzle flash. That rifle cannot possibly be identified beyond "has a reasonably long, fairly featureless barrel", but it is present.
Howa AR-18
A Howa AR-18 is the rifle of Ichihachi ("one-eight"), Ichiroku's cousin and Funco's roommate. Originally developed by ArmaLite, the AR-18 was also produced under licence by Howa in Japan and Sterling in England. Interestingly, Ichihachi being "born" in Japan makes her the closest thing to a Japanese character in the show, though she's still considered to be American.
Howa Type 89-F
A Howa Type 89-F is seen on a rack when Sig claims that Ichiroku is cheap. What appears to be another Type 89-F is seen on a film poster in Funco and Ichihachi's room, which is very fitting as the Type 89 is a direct development of the AR-18, designed by Howa from their experience producing AR-18s.
IMI Galil AR
Personification of the IMI Galil AR, Galil serves as Sako's right hand until after the tournament, where it's revealed that they could not possibly be more different in personality. Laid back and energetic, Galil becomes fast friends with Ichihachi, and later Mimi. Despite lacking the bipod (and therefore bottle opener) of the otherwise-identical Galil ARM variant she is seen attempting to open a bottle with her teeth, prompting a worried Ichihachi to give her a proper bottle opener instead, saying that doing that will damage her feed lips. This is a reference to a bottle opener specifically being designed into the Galil ARM, as Israeli soldiers had a notorious habit of damaging the feed lips on their Uzi magazines.
M16
The original-pattern M16 is seen during the history of the L85. The narrator mentions that after the Americans pressured NATO into adopting 7.62x51mm as the new standard, putting an end to many domestic projects like the British EM-2, the narrator then immediately follows up by noting that not too long after this the Americans turned around and adopted an intermediate cartridge anyway, with the M16. An M16 is also seen during the summary of its involvement in the Vietnam War, featuring a detailed blueprint-style drawing in the background.
M16A1
The M16A1 makes several appearances during technical and historical cut-ins, including during an explanation of three-round burst mode, the overview of its role in the Vietnam War, and when Ichiroku has a brief flashback to that time in her life.
M16A2
An M16A2 is seen in during a summary of the M16's history, this time narrated by Ichihachi rather than the usual narrator.
M16A3
An M16A3, the rare full-auto version of the A2, is also seen in the lineup of M16 variants. This marks one of exceptionally few times a "true" M16A3 appears in media, as opposed to the auto-converted A2s seen in most live action productions.
M16A4
At the end of this list of M16 variants is the M16A4, personified by Ichiroku ("one-six"). With high enthusiasm tempered by low stamina (being restricted to burst mode), Ichiroku is tomboyish and a natural leader. Due to the M16's fame and popularity, she also does modelling work. During the jungle tournament Ichiroku mistakenly eats an especially spicy chicken nugget that Funco accidentally made with chili pepper instead of paprika, causing her stomach to act up. This serves as a representation of the bad gunpowder infamously used in the M16 in Vietnam, which was largely responsible (along with other factors) for its notoriously bad reliability. As a result, Ichiroku's rifle quickly fouls up during the match, forcing her to operate the forward assist after every shot. A narrated cut-in explaining the rifle's direct impingement system refers to it as the "Ljungman system", referencing the Swedish ag m/42, an early example of a rifle using this system.
Golgo 13's custom M16
The customized M16 from the Golgo 13 manga, used by its titular character makes a cameo appearance in Curly's shop. Airsoft manufacturer Tokyo Marui made a limited production run replica of this custom M16, which is likely what was used for reference. The rifle is an M16A2 fitted with a flattop upper reciever; while this setup also describes the M16A4, this rifle specifically started out as an A2 and had its upper receiver replaced, and as such retains A2 markings on its lower receiver. It is also fitted with what appears to be an HK claw mount fitted to a picatinny rail adapter, essentially making it an overly-complex riser for the large scope mounted atop. It also features a custom cheek riser, something necessary for such a high-mounted scope, a cut-down carry handle as a rear ironsight, and uses 20-round mags.
Colt Model 653
A Colt Model 653 with a 16-inch barrel is seen during the history of the M16, shown as an example of one of the M16's many derivatives.
M4A1
A customized M4A1 is seen during a summary of why weight is an important factor.
Norinco Type 86S
A full-auto-capable Norinco Type 86S appears in the hands of its personification, a member of the Akaganekou faction. She is credited as 86式自動步槍 (86 shì zìdòng bùqiāng / Type 86 automatic rifle) in both the anime and manga, the rifle's full Chinese designation but with the "S" omitted. The "S" suffix on Norinco designations denotes semi-auto-only rifles (for example the semi-auto Type 84S and its full-auto sibling, the Type 84), and as such the rifle's full-auto capability paired with the consistent, deliberate omission of the "S" implies that within the Upotte!! universe Norinco developed a full-auto variant of the Type 86S, naturally named Type 86. She isn't known to have a more "conversational" name, but in the interest of simplicity and clarity this page will refer to her as 86; whether this is pronounced in Chinese, Japanese, or English is left up to the reader.
Norinco QBZ-97
A Norinco QBZ-97, the 5.56mm export variant of the QBZ-95, is used by a Seishou student at the firing range. This is consistent with other Eastern rifles' NATO export variants attending the Western-themed Seishou, such as Sako.
Sako RK 95 TP
The exceptionally rare 5.56mm export variant of the Sako RK 95 TP is personified by Sako. Domineering and sadistic, newly-transferred Sako attempts to bully her way through the jungle war games tournament with the apparent goal of taking over Seishou Academy.
SIG SG 550
Sig is the personification of the SIG SG 550. Smart yet somewhat of an airhead, Sig is a superb marksman, able to hold her own against the battle rifle characters at longer ranges. She is noted to use the Swiss GP 90 cartridge, a domestic version of 5.56mm NATO. While safely interchangeable with standard 5.56mm (Belgian SS109), the GP 90 cartridge features a notably heavier bullet for better performance at longer ranges, and as such is intended to be used with a different rifling twist rate. The SG 550 comes in two externally identical variants, the (domestic) SG 550-1 with a 1:10 twist rate for the GP 90 cartridge, and the (export) SG 550-2 with a 1:7 twist rate for standard 5.56mm. As such, Sig is specifically the SG 550-1 variant. Her rifle is often seen equipped with its proprietary Hensoldt ZF 6×42 BL scope.
SIG SG 552
A SIG SG 552 is briefly seen when Ichihachi notes that Sig is frequently featured in movies, prompting Sig to complain that she's referencing the wrong model.
Steyr AUG A1
The Steyr AUG A1 is personified by Aug. She often switches between two different barrel lengths, represented by her natural long hair (508mm standard barrel) or a short-haired wig (350mm compact barrel), with the former bringing out her more aggressive and enthusiastic "true" personality, while the wig suppress this and makes her notably quiet and shy. She is also able to equip the extended 621mm AUG HBAR barrel, at which point her personality is said to become incredibly overbearing. Tei and the narrator use the English loanword "heavy barrel" (not used for her standard/long barrel) and the narrator further makes reference to this allowing the AUG to become a light machine gun, however the visual mistakenly depicts the AUG with its standard/long barrel instead of the HBAR's longer barrel and integrated bipod. Aug also wears glasses, which (as with Sar) likely represent the rifle's built-in optic. An AUG A1 is also seen in Curly's shop.
T91
The T91 appears in the hands of Tei, nicknamed "fountain head" by Ichiroku due to her six ponytails; her hairstyle may be a reference to the logo of the 205th Arsenal, the rifle's manufacturer. The T91's collapsible stock is drawn attention to in parallel with the AUG's interchangeable barrels, highlighting the two characters' adaptability. Having an adjustable-length stock also comes with the side effect of Tei having adjustable-length panties (tied on the sides like a bikini bottom). Just before her rifle starts jamming Ichiroku manages to hit the T91's stock, damaging it and knocking it off the rifle, which also causes Tei to lose her panties in the process. A T91 is present in Curly's shop as well.
wz. 88 Tantal
A wz. 88 Tantal, the Polish equivalent to (but not copy of) the AK-74, is wielded by an Akaganekou student during the shootout in Atami. This rifle serves as a stellar example of the sort of "similar but different" rifles that the rest of the Akaganekou "extras" should canonically be wielding, instead of standard AK-74s. The character's name is never given, but she presumably goes by Tantal.
Battle Rifles & Rifles
Fabrique Nationale SCAR-H
Magazines for the FN SCAR-H are seen during the lengthy summary of the differences between assault rifles and battle rifles, specifically when noting that smaller, lighter intermediate rounds allow for more total ammo to be carried. The SCAR-H magazines sit next to a stack of FN-pattern 5.56mm STANAG mags, which were originally developed for the FNC and later continued to be used for the F2000 and SCAR-L. Compared to typical American GI-pattern STANAG mags, FN mags are built from steel (rather than aluminum), have a darker finish, and their most obvious visual difference is that two of the three reinforcing grooves do not extend all the way through the bottom of the mag, ending just above the floorplate.
Heckler & Koch G3A3
G3 is the physical embodiment of the Heckler & Koch G3A3, and unsurprisingly has numerous sisters (G3-based roller-delayed rifles) and cousins (other HK rifles). The rest of the HK family within Upotte!! consists of HK33E, G41, and G36 in middle school, HK53, MP5A2, MP5SD, MP5K, UMP, and MP7A1 in elementary school, and the elusive HK32 (an HK33 in 7.62x39mm) who attends Akaganekou due to her cartridge. All except G36 and HK32 live together in the same dorm, with (alongside G3 and MP) UMP, MP5K, and MP7A1 being seen and the remaining four being heard off-screen in the epilogue episode. G3 has modified her rifle by replacing the standard diopter rear sight with the aperture rear sight from the HK21, claiming she wants to be able to aim at targets out to 1000m away, though when pressed she admits her eyesight isn't actually good enough to make use of this. As such, when in longer range engagements she equips a Tasco Titan 3-12×52 scope fitted to an HK claw mount; its markings are legible in the manga.
L1A1
Funco's elder sister Fal is the British L1A1, often listed as "FAL L1A1" in the anime/manga, likely for clarity. Beautiful, smart, and an excellent tactician, Fal embodies all the traits of an admirable older sister. In the show as it aired Fal is at one point seen firing a burst of full-auto, something the semi-auto-only L1A1 is not capable of. This was corrected to three rapid shots in semi-auto for the BD release.
C1A1
A C1A1 is shown during the history of the L85. The Japanese text simply reads "early version FAL" and gives a cartridge listing of 7.92x33mm Kurz, which seems to be mixing up two FAL variants that independently are both very relevant to the topic. Canada was the first country to adopt the FAL, with the Canadians being responsible for converting its specifications from metric to imperial, thus creating the "inch-pattern" FAL. The British L1A1 (Upotte!!'s Fal) and Australian L1A1 were both derived from the Canadian C1A1. The C1 has several features quite distinct from other FAL variants (including its Commonwealth siblings), most notably an open-topped receiver with a stripper clip guide as well as a different rear sight.
The mention of 7.92x33 Kurz is a reference to the FN Universal Carbine, the very first prototype of what would become the FAL. Developed almost immediately after WWII, the Universal Carbine would quickly evolve into the FN Automatic Carbine in .280 British, before the American insistence on adopting 7.62x51mm as the new NATO standard forced FN to adapt their rifle for that cartridge.
M1 Garand
An M1 Garand is shown in "Take a Look! Scold Someone!", which is a wooden replica of the gun placed on the sign on the entrance to the Seisho Academy annual fair.
Springfield M14
16's elder sister 14 (Ichiyon in Japanese) is based off the M14. She first appears in "Grip and Hold!". A few M14s are seen in "Sing! Compete!". 14's accuracy when firing her rifle in full auto is non-existant; 16 even claims that the spread of her rounds is roughly 10 meters. This is a reference to the M14 being notoriously difficult to control in full-auto due to the heavy recoil of its 7.62x51mm ammo.
SKS
An SKS rifle appears in "Wash and Scrub!" during the explanation on the origin of bullpup rifles.
