Product Description
The B5 Systems Sierra K is a purpose-driven, compact stock optimized for PDW and other compact weapon systems. Designed to keep overall length down while maintaining a comfortable cheek profile, it features a snag-free adjustment lever, internal tensioners for a solid fit, and an anti-slip buttpad for consistent shoulder placement. The Sierra K integrates both limited-rotation quick-detach (QD) and fixed sling mounting points and is built with mil-spec materials/finishes and color-matched steel hardware. It mounts via a shortened compact Mil-Spec receiver extension using the Sierra K Receiver Extension Kit.
