flat spring no boing by Arsaregood, Verified Owner, November 1, 2025
Spring is heavier and doesn’t create that trampoline spring sound like a stock carbine does. If you’re running a select fire, FRT, or Super Safety I highly recommend this spring for your rifle or pistol to aid in the increased fire rate. I’ve gone th...

Strike Industries AR Carbine Flat Wire Spring by GreenLight, Verified Owner, February 8, 2026
I initially purchased this flat wire spring for an AR9 SBR build. I was trying it for the "blowback9" gentle recoil system. Its ID is too small and binds on the hydraulic buffer. I put it in a standard buffer system, and it works as advertised. S...

Put this buffer spring in an AR9 (SBR) build with a DTT FTR. Flat wire spring was recommended as part of the “Gentle Recoil System”. Ran flawlessly.

very good buffer spring by Concours14, Verified Owner, September 14, 2024
I’ve purchased many of these flat-wire buffer springs. They’re very well made and last a long time. I prefer them to a standard buffer spring. Seems to lock the bolt better, especially using reloads. Using small base reloading dies are definitely b...
