A2 LR-308 and AR-10 Rifle Buffer, 5.5 oz, Black

The A2 LR-308 and AR-10 rifle buffer is a 5.5 oz rifle-length buffer for LR-308 and AR-10 platforms. It uses an A2 rifle buffer configuration with steel and aluminum construction, a weighted internal buffer system, and drop-in compatible fitment with A2 rifle-length buffer tubes and standard rifle-length buffer springs. Color may vary.

Construction and Design

The A2 rifle buffer is steel and aluminum construction with a weighted internal buffer system at 5.5 oz. The A2 configuration is the standard rifle-length buffer design for LR-308 and AR-10 platforms using a rifle-length receiver extension. The internal weighting addresses the cycling dynamics of the LR-308 platform by providing the mass needed to control bolt carrier velocity during the rearward and forward cycling stroke. The buffer interfaces with the rifle-length buffer spring inside the receiver extension, with the spring and buffer working together to absorb rearward bolt carrier energy and return the carrier forward into battery. At 5.5 oz this buffer covers the standard weight specification for a rifle-length LR-308 and AR-10 buffer. Drop-in compatible fitment with A2 rifle-length buffer tubes means no modification is required for standard LR-308 and AR-10 rifle-length receiver extension builds.
