Originally manufactured by Olympic Arms as a semi-automatic rifle, then converted by John Norrell to a selective fire automatic rifle. The upper receiver is A2 pattern, with an AAC combination flash hider and silencer mount, Magpul MOE handguard, and bulls-eye pattern forward assist. The lower receiver bears the SGW/Olympic markings on the left side, with Norrell's address on the right, with a hole added for the sear pin and the selector stop cut away to allow full movement of the right handed selector switch, and a MOE grip and six-position telescoping buttstock installed. The bolt carrier is full auto configuration, with both the carrier and bolt head matte black finished and unmarked. Included with the rifle is a manual and an additional upper receiver, A1 pattern, with 3-prong flash hider, unmarked pencil profile barrel, triangular handguard, bullseye forward assist, and a bolt assembly finished and marked similar to the one in the A2 upper. Magazine absent.

Excellent, with 90% plus matte black phosphate finish, showing light handling marks overall, some rubbing on the rear of the lower receiver, and a red spot (possibly paint) on the left side of the barrel on the A2 upper. The furniture is in equal condition. Mechanically excellent.
