AeroPrecision
The Aero Precision Mil-Spec AR-15 Buffer Spring is a straightforward replacement component for AR platform rifles and carbines. Whether you're building a complete rifle from the ground up or swapping out a worn buffer spring, this mil-spec part delivers the reliability you need. Aero Precision manufactures this spring domestically, so you're getting quality made right here in the USA.
Buffer springs are one of those parts that rarely get attention until they need replacing—they work quietly in the background of your bolt carrier group, handling thousands of cycles. A compromised spring can lead to inconsistent function or reliability issues downrange. This mil-spec spring ensures your AR cycles smoothly and consistently, whether you're at the range, hunting, or running drills at your local match.
The silver finish is straightforward mil-spec standard. The key detail: make sure you're matching the right spring to your configuration. Carbine models with collapsible stocks use a different spring than rifles with fixed A2 or A4 buttstocks. Get that part of the equation right, and this Aero Precision spring will handle the job without fanfare or fuss.

No—pay attention to your build. Carbine models with collapsible stocks require a carbine buffer spring. Rifles with fixed A2 or A4 buttstocks use a rifle buffer spring. Using the wrong spring for your configuration will cause reliability issues. Check your buttstock type before ordering.
Yes, assuming you're matching it to the correct configuration. If your AR currently has a mil-spec spring and you're staying with the same stock type, this will drop in as a straightforward swap.
Domestic manufacture means quality control and support from a known source. Aero Precision builds their parts stateside, so you know where it comes from and can stand behind the maker.
