Physical Description

A bullpup mock-up rifle produced from finished Sterling AR-18 assemblies and components. Normal markings are present, save for the serial number (which may not have been applied until a weapon was completed). No pistol grip assembly is fitted, and the trigger and grip screw holes have been covered with a butt-stock that has been cut down to serve as a butt-plate. The trigger group housing has been cut out of a second lower receiver, complete with grip, trigger and trigger guard, and mounted onto the bottom of the lower handguard. No attempt has been made to connect the trigger to the actual trigger mechanism inside the actual lower receiver. An additional set of iron sights have been attached to the front of the upper receiver (on a u-shaped bracket) and existing front sight block. Where original finish has been removed, black spray paint has been used to cover it.
