Strike flat wire spring quiet
Reviewed on May 2, 2026Verified with Build

Strike Industries flat wire buffer spring is meaningfully quieter than a standard round wire spring, no twang you can feel through the stock. Cycles smoothly on a 16 inch carbine. Length and free standing dimensions match milspec carbine springs. Solid upgrade.
