Aero Precision
Overview
The Aero Precision AR-15 Carbine Recoil Buffer Spring is specifically designed to provide reliable cycling in carbine-length gas systems. With its tailored length, this spring helps ensure optimal operation and reduces felt recoil, contributing to a smoother shooting experience. It's commonly found in builds featuring a mid-length gas system and chambered in 5.56 NATO, making it a solid choice for those configurations.

Aeros 17-7 stainless carbine buffer spring is a noticeable upgrade over a basic music wire spring. Quieter cycle and less spring twang you can feel through the stock. Fits any milspec carbine extension. Aeros QC keeps the coil spacing consistent end to end.
