Buffers & Buffer Tubes

Browse our selection of AR-15 buffers and buffer tubes. Carbine, rifle and pistol receiver extensions carry the stock or brace, and the buffer weight and spring tune how hard the carrier cycles: heavier H2 and H3 buffers calm an overgassed or suppressed rifle. Castle nuts, end plates and complete assemblies are here too.
