The Killing Machine is a 2010 action film that was the sixth independent film directed by Dolph Lundgren, who stars as a former KGB agent-turned-mafia hitman who must protect his family after he is targeted for execution by unknown forces. The original title is Icarus.
The following weapons were used in the film The Killing Machine (aka Icarus):
A Desert Eagle Mark XIX fitted with a suppressor is used by Edward Genn/Icarus (Dolph Lundgren) during the opening assassination scene in Hong Kong.
Beretta 92FS Inox
Icarus' sidearm of choice for most of the movie is a Beretta 92FS Inox. Due to a continuity error, his Beretta tends to become a nickel-plated Taurus PT92 (often in the space of the same scene).
Taurus PT92
In some scenes (or even within the same scene), Icarus' Beretta 92FS Inox is replaced by a nickel or stainless Taurus PT92.
Walther P99
The assassins who attempt to kill Icarus and his ex-wife Joey (Stefanie von Pfetten) at the hotel are armed with suppressed Walther P99s, one of which is taken by Joey and used to save Icarus. He later shows her how to use the weapon.
Icarus also uses a two-tone P99 in Vadim's (Bo Svenson's) mansion, after taking it from one of his henchmen.
M1911A1
Vadim (Bo Svenson) and several of his henchmen carry nickel-plated M1911A1 pistols as their sidearms. Vadim's 1911 has pearl (or pearlite) grips.
During the flashback to his days as a KGB officer, Icarus is seen using Makarov PM (which actually appears to be a non-firing rubber stunt version).
Shotguns
Remington 870
During the shootout at Kerr's farm, Icarus (Dolph Lundgren) grabs a Remington 870 and uses it for most of the shootout. Due to a continuity error, it continually alternates between a standard police riot model and a Slug Gun (recognizable by the rifle sights).
Valtro PM5
A Valtro PM5 shotgun with a cut-down barrel is used by Icarus (Dolph Lundgren) in the climax of the film.
Rifles
M4A1 Carbine/Olympic Arms K3B-FT
M4A1 carbines fitted with Knight Armament Company RAS forearms and vertical grips are used by Vadim (Bo Svenson) and his henchmen. When the M4s are issued from his gun safe in the climax of the film, many of them clearly have the "Stowaway" pistol grip only found on the K3B-FT, the Olympic Arms copy of the M4. Also, the non-firing M4s in the movie are actually Classic Army M15A4 airsoft replicas of the M4 (see below).
Classic Army M15A4 airsoft replica
Some of the non-firing M4A1 carbines seen in the climax being used by Vadim (Bo Svenson) and his henchmen are actually Classic Army M15A4 airsoft replicas of the M4. They are recognizable by their white-painted fire position markings on the lower receivers (which no real AR-15 manufacturer uses).
AK-47
During the flashbacks to Icarus' days as a KGB officer, a milled receiver AK-47 rifle is seen carried by another KGB agent. The weapon appears to be a Hudson model gun replica.
AKS-74U
AKS-74U compact assault rifles fitted with suppressors are used by the hitmen disguised as construction workers who attempt to kill Icarus.
Submachine Guns
Skorpion SA Vz 61
Skorpion SA Vz 61 machine pistols fitted with suppressors are used by the Triad body guards in the opening assassination scene in Hong Kong.
Heckler & Koch MP5A3
Heckler & Koch MP5A3 submachine guns fitted with Surefire forearms, flashlights, sound suppressors, and red-dot sights are used by the hitmen who attempt to kill Icarus' daughter Taylor (Katelyn Mager) in his house.
Heckler & Koch UMP
Heckler & Koch UMP submachine guns (either .40-caliber of .45 ACP models) are used by the CIA black ops personnel in the movie, fitted with vertical grips, green laser sights, and red-dot sights.
Zoraki 925
In the climax of the film, Icarus (Dolph Lundgren) uses a pair of blank-firing Zoraki 925 machine pistols with M16A1-style flash hiders.
MAC-10
A suppressed MAC-10 (with the stock and front sight removed) is used by one of the Russian hitmen in the climax of the movie.
