Product Description
The Armaspec Gen3 Sound Mitigation Buffer (SMB) for AR-10 is a single-stage, captured, drop-in replacement for a standard buffer and spring. Designed to reduce spring noise by preventing the buffer spring from rubbing the inner wall of the buffer tube, it delivers smoother, quieter cycling and can help reduce felt recoil. The system features adjustable spring weight and is made in the USA, making it a strong upgrade for AR-10 and LR-308 pattern rifles.
