The Wilson Combat .458 Cal Quell K Mount Muzzle Interface is designed for easy installation using a standard 7/8 inches, 12-point socket wrench. Featuring a black nitride finish, this muzzle interface significantly reduces flash, delivering performance similar to the M16A1 flash hider. It's one of the most efficient and effective muzzle mounts available today. This interface is a critical component for connecting the Quell suppressor system, providing exceptional flash reduction and muzzle control, all without requiring an additional suppressor. Effectively reduces recoil and muzzle rise
