Armaspec Gen 3 Black H-Weight Sound Mitigation Buffer

The Gen 3 Armaspec Sound Mitigation Buffer in H-weight is a captured buffer and spring system for AR-15 rifles that call for an H buffer. The spring rides on a guide rod, so it never touches the inside of the buffer tube. That contact is what causes the twang most AR-15 shooters hear on every shot.

Keeping the spring off the tube wall makes cycling smoother and quieter. The system replaces the existing buffer and spring as one unit, with no gunsmithing. In the package you get the buffer, the spring, and a polymer base guide rod.

This H-weight version is for AR-15s, and Armaspec makes a separate version for 9mm AR builds. The SMB is a single-stage system, while Armaspec's Stealth Recoil Spring is multi-stage, so match the product to your rifle's setup. Browse more Gun Parts & Accessories for other AR-15 internals.
