The Warwick Firearms Australia Jacketed Muzzle Brake pairs a 66 mm brake with a 75 mm outer jacket that directs blast and noise forward, away from the shooter and the people beside you on the mound. Australian designed and made in chromoly steel; choose 1/2×28 for .223/5.56 or 5/8×24 for .30 calibre barrels.

The Warwick Firearms Australia Jacketed Muzzle Brake is a two-piece muzzle device: an inner muzzle brake plus a threaded outer jacket (sometimes called a blast shield or linear compensator). It is offered in 1/2 x 28 TPI for .223 / 5.56 barrels and 5/8 x 24 TPI for .30 calibre barrels such as .308 Winchester and .300 Blackout, and was developed by Warwick as a factory accessory for its WFA1 and WFA1-L rifle family.
The inner brake is 66 mm long and tightens with a 19 mm open-end spanner. The outer jacket is 75 mm long by 34 mm wide and is notched so a standard AR armourer’s wrench (the castle-nut section) can tighten it. Both parts are machined from chromoly steel, gas nitrided and blackened. Warwick notes the jacket does not reduce the sound level; it projects the muzzle blast and noise forward, which makes a braked rifle far more pleasant for neighbouring shooters on a range line. Warwick backs the brake with its 100% money-back guarantee, and Cerakote finishes are available direct from Warwick.
Which thread do I need? 1/2 x 28 TPI is the standard US military thread for .223 / 5.56 barrels; 5/8 x 24 TPI is the standard for .30 calibre barrels including .308 Winchester and .300 Blackout. Check your barrel’s thread before ordering.
Does the jacket make the rifle quieter? No. Warwick states the jacket does not reduce the noise level; it projects the blast and noise away from the shooter, which is why it is popular on range lines.
What tools are needed to fit it? A 19 mm open-end spanner for the inner brake and a standard AR armourer’s wrench (castle-nut section) for the outer jacket.
