The TacFire Thread Crown Muzzle Brake (brand part no. MZ1021) is a steel muzzle brake built for 5.56x45mm NATO AR-15 rifles with a 1/2-28 tpi thread and a 2.05-inch overall length. TacFire machines the brake with an integrated crowned thread profile, protecting the crown while giving the muzzle device a clean, finished look at the end of the barrel. It is constructed of steel and finished in black oxide for corrosion resistance, and TacFire builds it to standard AR-15 thread specifications. Shooters looking for a straightforward thread-on brake with a built-in crown protector get both functions in one part.
