AIM GI stock rubber pad
Reviewed on May 10, 2026Verified with Build

AIM Sports GI style stock body is lightweight but solid feeling. Rubber butt pad grips a jacket or plate carrier well. Polymer is thicker than the original GI version. Locks tight on a milspec carbine tube. Budget priced functional stock.

AIM Sports GI style stock fix
Reviewed on April 8, 2026Verified with Build

AIM Sports basic GI style stock body to replace a damaged stock. The polymer is thicker than the original GI version, feels less brittle. Slides onto a milspec carbine extension and locks at each position. Budget priced for a basic stock replacement.
