Improve Your AR-15’s Recoil with a Flat Wire Buffer Spring

Made in the USA with cryo-treated 17-7 stainless steel, this flat wire recoil spring drops into your buffer tube to upgrade your recoil system. This spring dampens recoil when the gun is cycling, and increases the load on the rear of the bolt carrier to ensure reliable lockup into battery. This spring is sized for carbine buffer tubes, which is common for the vast majority of AR-15s with adjustable stocks.

Why is a flat wire spring better?

Traditional piano wire recoil springs tend to bind up and rattle inside the buffer tube. A flat wire spring not only minimizes noise, but also doesn’t bind. The flat steel flexes without coils getting bunched together while the gun is cycling. The compact size of each coil also allows more energy to be stored in the spring; this is what increases the force on the back of the BCG.

gas tuning via buffer spring

Needed to tune a 10.5" non suppressed carbine gas system with non-adjustable gas block. Ejection pattern was at 1 o'clock. Installed this spring with H3 buffer and ejection pattern is now at 3 - 4 o'clock. Holds up to repeated semi-auto fire and sustained full auto fire.

Thank you for taking the time to leave a review! We are so glad to hear that our AT3 Tactical Flat Wire AR-15 Buffer Spring was able to help you with gas tuning and improve your ejection pattern. We take pride in providing high-quality products that can withstand repeated use. Happy shooting!
