Featuring a stock body made from machined aluminum, this stock has two QD sling mounting points at the front of the stock and a textured butt-plate at the rear.

Classic style with creature comforts


I wanted a triangle stock for my GF3, but didn't want to have to fab my own pad and riser. This is a perfect setup. Mounts well and fits the AK platform, but still allows some padding.
