Colt produced a few variants of its 9mm SMGs, which Ian has covered in a video. They gave 9mm SMG options in an AR-15 form factor, though operating on blowback rather than the Stoner gas system. This is probably a Colt 635, which was the most common variant of the Colt SMGs.

The Wilcox Nightstalker Powergrip was a light and laser aiming combination that had the activation buttons built into the vertical grip. It could be mounted either directly to the barrel or to Picatinny rails.

The C-More was an early red dot sight, marketed in conjunction with Colt as a “Colt Scout Sight”, coming pre-configured with a mount for AR carry handles.
