Aero Precision AR15 Enhanced Pistol Buffer Kit

Building a reliable AR15 pistol means starting with quality components that'll handle real use. The Aero Precision AR15 Enhanced Pistol Buffer Kit gives you the core parts you need for a solid receiver extension assembly—all manufactured in the USA and engineered to mil-spec standards. Whether you're assembling your first pistol or upgrading an existing build, this kit keeps things straightforward: solid components, proven materials, no guessing.

The kit centers on an enhanced 7075-T6 aluminum pistol buffer tube, a material choice that balances durability and weight. You also get the buffer spring, carbine buffer, end plate, and lock nut—everything needed to complete the rear end of your upper and lower assembly. Aero Precision's attention to manufacturing detail shows in every part; these aren't bargain-bin pieces that'll wear out after a few hundred rounds.

Pistol builds have different geometry than rifle-length platforms, and using purpose-built parts matters. This kit is designed specifically for AR15 pistol configurations, so you won't be forcing rifle-length tubes into a platform that wasn't built for them. If you're running a short-barreled upper, a brace-equipped lower, or just prefer the compact profile of a pistol platform, this kit handles the job without compromises.
