Armaspec SMB-9 Buffer Kit Black/Silver AR-15 Gen3

The Armaspec SMB-9 Sound Mitigation Buffer Kit delivers a superior upgrade in place of the OEM mil-spec buffer and spring combination, packaged as a complete drop-in kit for 9mm Luger AR-15 builds.

This Gen 3 SMB is a single-stage captured drop-in replacement for the standard buffer and spring. It installs directly into compatible AR-15 Gen 3 lower receivers with no permanent modification required, making it a straightforward way to upgrade the buffer system of any compatible rifle.

Finished in a durable Black and Silver color scheme, the SMB-9 kit includes everything needed to complete the installation. Purpose-built for 9mm AR-platform (AR-9) rifles, it brings Armaspec's signature sound mitigation design to shooters looking to improve their AR-15 platform's performance.
