The Thunder Beast 338 BA muzzle brake allows the quick and secure attachment of both the 338 Ultra and 338 BA silencers to the host rifle. The precision machined taper insures consistent and solid lockup when mounting the suppressor to the 338 BA brake. Designed around accuracy, the brake not only serves as an attachment method for the suppressor, but also reduces recoil significantly when shooting unsuppressed. A peel washer is included for timing and installation.
