AR-15 and AR-10 Buffer Parts for Recoil Assemblies

Buffer parts keep the recoil system of your AR build functioning as intended. This category covers the core components that mount and retain your buffer tube assembly, including carbine buffers, carbine buffer tubes, steel castle nuts, and end plates. White Label Armory offers these American-made, mil-spec components for AR-15 and AR-10 platform builders working on new assemblies or replacing worn hardware.

When selecting parts, confirm compatibility with your platform and pick the end plate configuration that fits your needs. Mil-spec and ambidextrous dual loop end plates ship in five-packs, and steel castle nuts in five-packs help secure the receiver extension. A matched AR15 carbine buffer and carbine buffer tube round out the recoil assembly.

To complete a lower, pair these with pre-assembled buffer kits. These components suit individual builders and firearms manufacturers sourcing parts through white-label manufacturing partnerships.
