(Finally manged to find an SKS and Blaser 95 while in good health. Also came across the M1911 and the Mk 3, as well as finally putting the Mosin to paper. A few edits of placement - Let's put items on the page, in categories, by release.)
The [[Ruger 10/22]] is an upcoming weapon, chambered in .22LR.
The [[Ruger 10/22]] is an upcoming weapon featured in the latest patched, chambered in .22LR. It can utilise either the standard 10 round rotary magazine or use a 30 round aftermarket magazine.
The FN FNP-45 Tactical, called the "FNX-45" in game, is one of the .45 semi-automatic handguns in the game. It uses 15 round .45 ACP magazines, and accepts a red-dot sight as well as pistol flashlight. The model appears to be a redone version of the "4-Five .45" taken from ArmA 3, as it even sports the same attachments.
CZ 75 SP-01 SHADOW
The CZ 75 SP-01 SHADOW is featured as one of the 9x19mm handguns available. It's know ingame as the CR 75, and is made by "Cheraruska Zbrojovka", an odd spin on the real world CZ company.
M1911A1 Variant
An M1911A1 variant is available in the game. Not sure of specifics.
AWC Amphibian S Ruger MKII
The AWC Amphibian S Ruger MKII is an upcoming handgun to be added to the game. It will likely have the standard 10 round .22LR magazine. It is intriguing that a very expensive variant of a pistol used by U.S. Navy SEALs appears in the game, at all.
Revolvers
Colt Python
A chrome Colt Python, known as the "Magnum .357" in-game, appears as (currently) the only revolver in the game. The Colt Python is correctly chambered in .357 Magnum, and accepts a speedloader for faster reloading.
Shotguns
Baikal IZH-43
The Baikal IZH-43 appears as the "IZH-43", and correctly uses 12 Gauge (Both pellets and slugs). A Sawed-Off IZH-43 can be created using a hacksaw, increasing the recoil and decreasing accuracy but taking up less inventory space. It can be loaded with twin-shell speedloaders.
Rifles
Blaser B95 "Luxor"
The Blaser B95 "Luxor" appears as the "Blaze 95 Double Rifle", chambered in 7.62x51mm (Which is one of many calibers the B95 supports). It has a measly two round capacity, but is very accurate.
M4A1 Carbine
The M4A1 Carbine appears, being the only select-fire weapon as of yet. It is correctly chambered in 5.56x45mm ammo, and features the widest amount of customization available to any weapon (Accepting everything from black and OD Magpul stocks and handgrips, to Aimpoint M68 CompM2 and ACOG sights.) It also has the largest variety of magazines; being the standard 30-round STANAGS, as well as 10, 20, 30 and 40 round Magpul P-Mags (All in fashionable black and OD green) and two coupled 30 round STANAG mags.
Mosin Nagant M91/30
The Mosin Nagant M91/30 appears as the "Mosin 9130". The weapon incorrectly uses 7.62x51mm ammo (and prior to the addition of the SKS, used ambiguous "7.62mm Ammo"). The Mosin-Nagant M91/30 can be equipped with a few attachments, including a 12x Scope, M44 Compensator, and M91 bayonet. The Mosin-Nagant can be spray painted black, green, or a camouflage mix of both.
Ruger 10/22
The Ruger 10/22 is an upcoming weapon featured in the latest patched, chambered in .22LR. It can utilise either the standard 10 round rotary magazine or use a 30 round aftermarket magazine.
SKS
A Yugoslavian SKS M59/66 appears, simply, as the "SKS". It is correctly chambered in 7.62x39mm, and accepts a bayonet as well as PU scope. The SKS, like the Mosin-Nagant, can be spray painted either black, green, or a camouflage mix of the two.
