B5 Systems SIERRA K Stock – AR-15/M16 (Wolf Gray)

The B5 Systems SIERRA K Stock delivers a compact, stable shooting platform for AR-15 and M16 rifles where length of pull matters. Its reinforced cheek weld and precision lockup eliminate rattle while maintaining a streamlined profile for tight quarters or vehicle work. The stock's geometry promotes consistent eye alignment with optics across all positions.

Constructed from reinforced polymer with an integral QD sling socket and anti-rotation feature for secure mil-spec buffer tube mounting. The SIERRA K includes dual water-resistant battery storage tubes in the core and a textured buttpad that grips gear without snagging. Installs on any mil-spec carbine buffer tube without tools or modification. Wolf Gray finish coordinates with modern multi-tone builds.
