B5 Systems AK Stock 4.5mm – AK-47/AK-74 Pattern Rifles

The B5 Systems AK Stock delivers modern ergonomics and solid cheek weld for AK-pattern rifles while maintaining a clean, mil-spec profile. Designed for shooters who want improved shoulder contact and consistent eye alignment without adding bulk, this stock enhances control during rapid transitions and follow-up shots.

Constructed from reinforced polymer with an internal steel locking lug, the stock fits standard 4.5mm AK rear trunnions found on most AK-47 and AK-74 variants. Installation requires no permanent modification—simply remove the factory stock and slide this unit into place. The textured buttpad provides secure shouldering even in wet conditions, and the streamlined design won't snag on gear or clothing.
