General Compensator FAQ

Compensators function by redirecting exhaust gas up and to the sides, this means there is less felt recoil energy for the shooter and less muzzle flip. Due to IGNIFICANTLY less recoil energy with a long compensator, you WILL need to use a lighter recoil spring for your gun to cycle correctly. In most cases the long comp will require tuning of the recoil spring and may also require tuning of the striker spring with low power 155gr target loads. This is a competition grade compensator, if you're not planning on tuning a race gun this is not the compensator for you, instead check out our short and mid comps designed for edc.

Firearms in images are shown for illustrative purposes only, they are not included with the compensator.
