Spike's Tactical AR-15 Variable Pitch Recoil Spring

The Spike's Tactical AR-15 Variable Pitch Recoil Spring is a carbine-buffer-tube compatible recoil spring designed for AR-platform rifles. It is intended to reduce felt recoil and to progressively slow the bolt carrier for smoother cycling across a range of applications, including 9mm blowback and .300 AAC Blackout systems. The component uses a variable-pitch coil profile that breaks up initial impact forces and acts as a mechanical cushion, and the spring is designed for standard carbine buffer tubes. The spring is manufactured in the United States.
