Aliens

The following guns were used in the movie Aliens

M41A Pulse Rifle

The USCM Marines famously use M41A Pulse Rifles as thier standard issue weapons. This weapon was made from a M1 Thompson machine gun with a Remington 870 shotgun underneath while some argue that the Grenade launcher is actually a SPAS 12. At the end, Ripley (Sigourney Weaver) tapes one of these rifles to an M240 Flamethrower when going to rescue Newt (Carrie Henn).

M240 Flamethrower

Another weapon used by the marines is the M240 Flamethrower, it most notably used by Gunnery Sergeant A. Apone (Al Matthews), Private M. Drake (Mark Rolston), and Ripley (Sigourney Weaver) when she famously tapes it to an M41A Pulse Rifle before she goes to rescue Newt (Carrie Henn). These flamethrowers also appear to have been created from M16 rifles.
