The Kel-Tec Muzzle Brake Kit for the RFB Rifle replaces the factory flash hider with an efficient muzzle device that helps to mitigate the gun's recoil and muzzle climb upon firing for faster follow up shots. The 3 chamber muzzle brake is machined from 4140 Steel and comes complete with a jam nut for proper timing on the barrel.
The factory flash hider must be torqued off the barrel. This may require a heat gun or torch to loosen the thread locking agent applied at the factory. The muzzle brake requires 2 thin 3/4" wrenches for installation (not included).
