The Armaspec SMB Buffer Kit, H Weight, Gen 3 for AR-15 is a buffer kit built around Armaspec’s SMB, the Sound Mitigation Buffer (Armaspec part no. ARM268H). Armaspec lists this one in the H weight and the Gen 3 design. It is made for AR-15 rifles, so it belongs on an AR-15 buffer system and not on an AR-10 or AR-9 build. The weight letter is part of the product name, so read it against the other SMB listings before you order.
