Our muzzlebrakes are manufactured and installed by Gruning Precision to the most strict aerospace tolerances. All too often one sees brakes improperly aligned to the bore, causing a detrimental effect upon accuracy. The master machinists at Gruning painstakingly indicate each barrel in the lathe before cutting threads and re-crowning to ensure near-perfect concentricity, so that the bullet is not tipped off balance as it exits the bore and passes through the brake.

Each Gruning muzzlebrake is custom manufactured and machined to fit your rifle. Except with some extra-slender barrels, the brake will be perfectly flush with the exterior contour of the barrel.
