GHK M4 GBB Enhanced Blowback Recoil Spring
The GHK M4 GBB enhanced blowback recoil spring is designed to be a robust and stiffer option to the stock spring found in the gun. For best effect, this spring is best paired with the GHK high-speed buffer and bolt set, but it can also work with standard stock bolt carrier groups compatible with GHK M4s as well.
