Finally after a long waiting period we received our exclusive (Pat. Pending) SIG 556 Flash hider / Muzzle brake. This Device is an excellent copy of the original SWISS SIG PE 90 SIG 550/551 Muzzle Brake. This part is machined with the highest quality materials available and your satisfaction is guaranteed. We do not provide the crush washer for the proper muzzle brake timing, since on all the SIG 556 rifles the barrel timing is different. We recommend using high temperature LOCKTITE Thread locker in order to secure the Muzzle Brake on the correct timed position.
