At the end of the film, Nestor (James Remar) can be seen using a MAC-10 with no barrel extension.

Rifles & Carbines

Carlos (Daniele Quinn) can be seen with a M16A1 when Joe (Stephen Lang) is teaching him marksmanship skills. It's assumed this is Joe's personal weapon as it's not one taken from Cream's men. Ruben uses the same M16A1 during the attack by Cream's gang. Carlos uses the M16A1 to provide covering fire for the rest of "The Band" when they attack the drug factory.
CAR-15
Carlos (Daniele Quinn) can be seen armed with a CAR-15 during the tactical training session.

Other
M61 Vulcan
A structure on top of the drug factory hides a gun turret containing a pintle-mounted rotary cannon. Grating on the structure folds down to allow the cannon to fire. The weapon closely resembles an M61 Vulcan but slightly smaller. It is not known if this is an actual weapon firing blanks or a prop gun constructed for the film. The cannon closely resembles the cannon mounted on the Blue Thunder helicopter, which is supposed to be a M61 Vulcan, but was a acetylene-firing mockup.
