B5 Systems Collapsible Precision Stock Medium – AR-15/M16 Platform

The B5 Systems Collapsible Precision Stock delivers consistent cheek weld and improved shoulder contact for shooters who demand repeatable accuracy from their AR-platform rifle. Designed with a competition-inspired profile, this stock provides enhanced stability during extended shooting sessions and reduces felt recoil through increased surface area and a refined butt pad geometry.

Constructed from reinforced polymer with a flat dark earth finish, the medium-length stock fits mil-spec carbine buffer tubes and features an internal anti-rattle mechanism for solid lockup. Tool-free installation via standard push-button adjustment. The extended contact area and precision-oriented design make this stock well-suited for designated marksman roles, competitive shooting, and any application where consistent rifle positioning matters.
