The same design and efficiency as our .223 AT15 muzzle brake, made with 5/8X24 TPI for the larger .308 AR-10s.

Tools required

-13/16” open ended wrench or adjustable crescent type wrench
-Anti-seize or other heavy grease
-Electrical tape (optional)
-Method to hold barrel or receiver

 

 

   Remove any existing device from barrel. Note- many firearms may have factory installed muzzle devices pinned or welded on.
   If you are not sure how to remove the device without damaging the firearm or
muzzle threads, stop and consult a gunsmith.

Once the existing device has been removed, inspect and clean muzzle threads. Apply a small amount of anti-seize or heavy grease to the exposed muzzle threads. Place the enclosed crush washer on the muzzle so that the flared side of the washer faces toward the AR10 muzzle brake. Ensuring it is not cross threaded, carefully hand screw the AR10 muzzle brake onto the muzzle until it is hand tight on the crush washer. The supplied crush washer will allow the AR10 muzzle brake to be tightened approximately 1/3 turn. If the brake is more than 180 degrees from 12 o'clock, remove the AR10 muzzle brake, flip the washer over and reassemble. We have had to remove metal from the crush washer in some circumstances. This can be achieved by dragging the small radius of the washer across some sandpaper on a flat surface.

Secure the barrel or receiver from turning utilizing an approved method.

With a 13/16” open ended or an adjustable wrench, tighten the AR10 muzzle brake until the "ATRS" engraving is at Top Dead Center (12o'clock). Hint: If using an adjustable wrench, wrap a couple of layers of electrical tape to avoid marring the finish of the AR10 muzzle brake.

Note- In order to provide maximum effective muzzle control, the AR10 muzzle brake is required to be "timed". Optimal timing is achieved when the engraved “ATRS” is in the 12 o'clock position. When the AR10 muzzle brake has been tightened, the "ATRS" engraving will be pointing in line with the vertical axis of the firearm. Wrench flats will be on top and bottom when tightened.
