Lake Placid 2
The following weapons were used in the film Lake Placid 2:
The big game hunter/poacher Struthers (Sam McMurray) carries an Italian Franchi SPAS-12, which he even refers to as a Franchi SPAS-12 in the film. He also mentions how the acronym stands for "Sporting Purpose Automatic Shotgun". His tube magazine is shorter than standard, appearing to hold less than the standard 8 shot tube of the SPAS-12. He only uses it once and changes over to the Browning A Bolt Shotgun for the rest of the film.
Mossberg 500 Persuader
Sheriff Riley (John Schneider) is seen carrying a Mossberg 500 Persuader at one point in the film, in which Struthers brags his SPAS-12 is bigger. Riley rarely uses the Mossberg, instead going for the fictional 40mm grenade launcher for the rest of the film.
Struthers (Sam McMurray) brings several Browning A-Bolt Shotguns. The bore and magazine plate indicates it is indeed the shotgun version, which is a rare variant of the A-Bolt no longer in production, and the film has at least two of them. Struthers' assistant Ahmad (Joe Holt) carries it when Struthers carries the SPAS-12. Emily (Sarah Lafleur) and Sheriff Riley (John Schneider) also uses the gun.
Double Barreled O/U Shotgun
Seen stacked against the wall behind Frank as he makes his statement.
Steyr Mannlicher M95/30 carbine
A Steyr Mannlicher M95/30 is seen among the long guns stacked up a wall.
Winchester Model 1894
Among the weapons seen in the Aroostook County Sheriff's office appears to be a Winchester Model 1894 rifle.
A Marlin 336C is seen among the long guns stacked up a wall.
Struthers (Sam McMurray) carries a Beretta 92FS pistol as his sidearm, as does Sheriff Riley (John Schneider). The gun appears to be a flashpaper gun, but since other guns in the film fire blanks, it can be assumed it was due to lack of a better prop instead of sound ordinance.
"Milkor MG-340" (Cobray M79LF Flare Launcher)
Aroostook County Sheriff Riley (John Schneider) uses a multibarreled launcher that referred to in the film as a "Milkor MG-340". In reality, this launcher is a Cobray M79LF 37mm Flare Launcher mocked up with a fake scope and an added on cylindrical drum to resemble a Milkor MGL, but making it look a lot like a Sentinel Arms Stryker). At one point in the film, the launcher's true identity is seen as Riley opens up the tube of the launcher, which moves the drum along with it.
