3FO Flash Hider V2 Outside Threaded - .223/5.56, 9mm, .30 Caliber

Breek Arms’ lineup of Outside Threaded Muzzle Devices is an affordable upgrade that gives you the option to run a flash hider or muzzle brake while utilizing our Breek Arms Castle Blast Shield as a forward blast diverter or concussion device. Simply slide the blast shield over the outside of the muzzle device and turn the blast shield on. This gives the shooter a more pleasant experience when firing especially for shorter platforms that tend to have an overbearing concussion. Added durability due to an updated heat treating process that increases reliability for higher muzzle pressures.
