The Sako/Tikka Tactical Conical Stainless Steel Muzzle Brake is designed for .30 caliber or smaller bore rifles from Sako and Tikka. The muzzle brake can be affixed to rifle barrels that feature 5/8-24 threading and helps eliminate recoil, muzzle rise, and flash. The asymmetrical design reduces dirt and dust kick-up when firing from the prone position.
