Ar-15/hk416 Carbine Buffer Tube

The AR-15/HK416 Carbine Buffer Tube is a direct impingement system component engineered for operators who demand reliability and precision in modern rifle platforms. Built by Heckler & Koch, a manufacturer trusted by military and law enforcement worldwide, this buffer tube serves as the foundation of your rifle's recoil management system. Whether you're building a tactical carbine, upgrading an existing AR-15, or maintaining an HK416 platform, this component is essential for consistent accuracy and shooter control under demanding conditions.

This buffer tube houses the recoil spring and buffer weight, directly influencing how your rifle absorbs and cycles the energy produced by each round. The design facilitates smooth bolt carrier group travel, reducing felt recoil and improving follow-up shot accuracy—critical factors in both tactical operations and competitive shooting. H&K's engineering ensures proper weight distribution and spring geometry, allowing shooters to pair this tube with compatible stocks and buffers to fine-tune their specific shooting dynamics. The robust construction withstands hundreds of thousands of rounds without degradation, maintaining consistent performance across various ammunition loads and shooting conditions.

Law enforcement professionals, military personnel, and civilian shooters building or maintaining AR-15 and HK416 platforms rely on this buffer tube for its proven durability and compatibility. Installation requires basic AR platform knowledge and standard tools; the tube threads directly onto the lower receiver extension. This component pairs seamlessly with mil-spec stocks and is compatible with standard buffer weights and springs, making it an ideal upgrade or replacement for operators seeking H&K-grade reliability. At 0.32 lbs, it maintains minimal weight while delivering maximum performance, ensuring your rifle remains balanced and controllable during extended shooting sessions.
