B5 Systems AK Stock 4.5mm – AK-47/AK-74 Pattern Rifles (OD Green)

The B5 Systems AK Stock delivers improved shoulder control and rapid target transitions for AK-pattern rifles. Designed with a streamlined profile and textured cheek weld surface, this stock reduces felt recoil and provides consistent alignment behind optics or iron sights during rapid strings of fire.

Constructed from mil-spec reinforced polymer with a non-slip rubber buttpad, this stock fits 4.5mm receiver trunnions found on most stamped AK-47 and AK-74 variants. The OD Green finish resists UV fading and chemical exposure. Installation requires removal of existing stock hardware—no permanent modification to the rifle. Compatible with standard AK rear sling attachment points.
