B5 Systems CAR-15 Stock OD Green Mil-Spec AR-15 Carbine Buffer Tube

The B5 Systems CAR-15 Stock delivers authentic military styling with modern manufacturing precision for AR-platform rifles. This OD Green synthetic stock combines the classic fixed-length profile of the original CAR-15 with enhanced durability and consistent cheek weld positioning.

What Makes This Different

Unlike adjustable carbine stocks that can develop play over time, the CAR-15 maintains a solid, non-moving connection to the buffer tube. The reinforced synthetic construction weighs 40% less than original fiberglass versions while providing superior impact resistance. Internal steel reinforcements distribute stress across critical mounting points, preventing cracking under heavy use.

Key Features

• Fixed-length design eliminates stock wobble and maintains consistent length of pull
• Reinforced synthetic polymer construction with internal steel components
• Mil-Spec buffer tube compatibility (1.146" diameter threading)
• OD Green finish matches military specification color standards
• Integrated sling attachment point for single-point or two-point configurations
• Textured buttpad surface provides secure shoulder placement
• 13.5-inch length of pull optimized for standard body armor clearance

Field performance centers on the stock's ability to maintain zero through temperature extremes and repeated impacts. The synthetic material resists cracking in sub-zero conditions while the steel reinforcements handle the stress of rapid-fire sequences. Competition shooters benefit from the consistent cheek weld, while tactical applications gain from the reduced snag profile compared to adjustable alternatives.
