The B5 Systems Precision Stock Collapsible Medium Black (CPS-1304) is a modernized receiver extension stock designed for Mil-Spec carbine platforms seeking precision ergonomics without sacrificing combat functionality. Built on the proven cheek weld profile of B5's legacy SOPMOD and Bravo stocks, the Precision variant integrates an adjustable cheekpiece and contoured buttpad, enabling shooters to dial in consistent sight picture and shoulder fit across varying shooting positions and body armor configurations.
Key specifications include pull-down length-of-pull adjustment with integrated lockout to prevent unintended collapse during use, ambidextrous quick-disconnect and fixed sling attachment points for tactical versatility, and an underside M-LOK accessory mount for mounting lights, cameras, or specialized equipment. Internal tensioners eliminate rattle and wobble on the receiver tube. The collapsible design compresses significantly for vehicle operations, building entries, and transitional spaces while maintaining stability when extended. At 1.45 lbs, the medium profile balances weight efficiency with structural rigidity across intermediate and longer-range applications.
The Precision Stock is engineered for operators and trainers who demand repeatable cheek indexing without the bulk of fixed stocks. Law enforcement tactical teams, military units conducting precision rifle work, and serious civilian marksmen benefit from the adjustable geometry for consistency across different shooting platforms and scenarios. The color-matched hardware maintains aesthetic continuity and reduces visibility of fastener edges under magnified optics.
B5 Systems stocks are standard-issue across special operations units and widely adopted in professional shooting communities for reliability and ergonomic refinement. The Precision Stock Medium competes directly with enhanced adjustable stocks in the mid-range tactical segment, offering the adjustable cheekpiece feature at a competitive price point compared to premium modularity systems.
Dimensions: 7 x 2.5 x 10.5 inches. Fits all standard Mil-Spec carbine receiver extensions (1.148" diameter tube). Available in black.
