SKU: B5CAR-1
The B5 Systems CAR15 Stock is a mil-spec replacement buttstock engineered for AR-15 and M4 carbine platforms where compact profile and lightweight performance are non-negotiable. Designed for operators who prioritize modularity and rapid reconfiguration, this stock incorporates B5's proven polymer construction and quick-detach mounting system, making it ideal for tactical professionals, military personnel, and civilian shooters who demand reliability in field conditions. The CAR15 stock has become a trusted choice across law enforcement and military units where dependable interface geometry directly impacts shot placement and weapon manipulation under stress.
Built to mil-spec dimensions, the B5 CAR15 Stock features a reinforced polymer body that resists impact and environmental degradation while maintaining a minimal weight footprint of just 0.44 lbs—critical for maintaining overall system balance on carbines used in extended operations. The integral quick-detach (QD) mount allows rapid stock swaps without tools, enabling shooters to transition between configurations or field-repair equipment within seconds. The stock's compact length of pull and ergonomic geometry support consistent cheek weld and shoulder indexing, which directly translates to improved shot grouping and faster target reacquisition—factors that matter in both training and real-world deployment scenarios.
Law enforcement tactical teams, military units, and serious civilian shooters benefit most from this stock's versatility and proven durability in high-round-count training and duty cycles. The Olive Drab Green finish offers a professional appearance while providing minimal reflectivity in field environments. Installation is straightforward on any mil-spec AR-15 or M4 platform, and the quick-detach system is fully compatible with standard QD sling attachments. This stock pairs seamlessly with both direct-impingement and piston-driven upper receivers, making it an essential component for anyone building or upgrading a reliable carbine system.
