The Aero Precision AR15 Rifle Buffer Kit gives you the three core components you need to complete your AR15 build or refresh a worn system. This mil-spec buffer kit includes a 6061-T6 aluminum rifle buffer tube, a rifle buffer, and a rifle buffer spring—all manufactured in the USA. Whether you're assembling an AR from a lower receiver, upgrading a barreled upper, or replacing a tired buffer group, this kit delivers the dependable US-made quality Aero Precision is known for without the guesswork of sourcing parts separately.

Mil-spec construction means your buffer kit will mate with standard AR15 stocks and work reliably with the vast majority of AR platforms. The aluminum buffer tube is built to handle the recoil impulse, while the matched buffer and spring work together to manage cycling and felt recoil. This isn't exotic—it's proven, no-frills AR engineering that's been running in rifles for decades.

Perfect for hunters, competition shooters, or anyone building or maintaining an AR15 rifle. Keep one on hand or build out a spare upper. Note that this kit does not include a stock; you'll need to source that separately to complete your lower receiver or swap out your current furniture.
