AKM

Another member of Beckett's unit is armed with an AKM in Season 3's "The Leap Home, Part 2".

AR15/SP1 fitted with M203

Blaster (Patrick Warburton) carries an AR-15/SP1 fitted with the M203 grenade launcher in Season 3's "The Leap Home, Part 2".

Screen used Faux M203 39mm launcher attached to an M16/SP1 rifle. Note that the film used multiple rifle/launcher combos, and the wear on the launcher actually changes from shot to shot, indicating that the actor is using the backup rifle/launcher combo for that particular shot.

CAR-15

Several members of the squad including Tom Beckett carry the CAR-15 in Season 3's "The Leap Home, Part 2".. The episode takes place in April of 1970, so the curved 30-round magazines would not be anachronistic.
