B5 Systems CAR-15 Black Mil-Spec Carbine Stock for AR-15 Platform

The B5 Systems CAR-15 stock delivers authentic military-specification performance for AR-platform rifles. This black synthetic buttstock replicates the original CAR-15 design with modern manufacturing precision and materials.

What Makes This Different

Unlike commercial carbine stocks, the B5 CAR-15 maintains true mil-spec dimensions and tolerances. The reinforced polymer construction eliminates the cracking issues common in vintage CAR-15 stocks while preserving the original profile. Six position adjustability provides 3.25 inches of length-of-pull adjustment, accommodating shooters from 13.5 to 16.75 inches.

Key Features

• Mil-spec carbine buffer tube compatibility with standard spring and buffer
• Six-position adjustable length of pull from 13.5 to 16.75 inches
• Reinforced polymer construction resists impact and environmental stress
• QD sling swivel socket integrated into rear of stock body
• Anti-rattle cam lever prevents movement during operation
• Authentic CAR-15 profile maintains classic carbine appearance
• Textured buttpad provides secure shoulder contact

Field performance remains consistent across temperature extremes and harsh conditions. The polymer material resists UV degradation and chemical exposure while maintaining dimensional stability. Competition shooters appreciate the repeatable lockup between positions, while duty users rely on the stock's ability to maintain zero after repeated adjustments. The QD socket accepts standard quick-detach sling hardware for rapid configuration changes.
