You can use a vise and a wrench to remove an AR muzzle brake.
- First, you’ll need to clamp the muzzle brake in the vise. Make sure that the vice is tight so that the muzzle brake doesn’t move around while you’re working on it.
- Next, take your wrench and loosen the set screws that hold the muzzle brake in place. Once the set screws are loose, you should be able to unscrew the muzzle brake by hand. If it’s difficult to remove, you can try using a pair of pliers or another tool to help turn it.
- Once the AR muzzle brake is removed, clean off any old grease or dirt that may be on the threads so that it’s ready to be reinstalled.
If you’re having trouble removing an AR muzzle brake, you can always bring it to a gunsmith or firearms dealer and they can usually remove it for you.
You can use a spanner wrench.
- Make sure that the rifle is unloaded and the magazine is removed.
- Locate the two notches on the outside of the muzzle brake (one on each side) and insert the spanner wrench into these slots.
- Simply rotate the wrench clockwise until the muzzle brake loosens and can be removed from the barrel.
If you don’t have a spanner wrench handy, you can also use two Allen wrenches of different sizes (one that fits into the small notch on the side of the muzzle brake, and one that fits into the larger notch). Simply insert the Allen wrenches into the respective notches and turn them in opposite directions until the muzzle brake loosens and can be removed. Finally, you can also use a pair of pliers to remove a muzzle brake, but this is not recommended as it can damage the finish on the muzzle brake.
Assuming you are referring to an AR-15-type rifle, the first step is to ensure that the weapon is unloaded. Once confirmed, proceed by pointing the muzzle in a safe direction and depressing the recoil spring plug retaining detent located on the left side of the receiver (as viewed from the rear). This will allow you to rotate the recoil spring plug counter-clockwise until it clears the gas key.
With the recoil spring plug moved out of position, you can now pull back on the charging handle, which will release the tension on the action spring allowing for the removal of the barrel assembly. After clearing and locking back the charging handle, unscrew the muzzle device and handguard cap, being careful not to lose the small washer located under the cap. The delta ring assembly can now be pulled off of the front sight base, allowing you to remove the handguards. At this point, the upper receiver group can be separated from the lower receiver by pushing out the two takedown pins.
There are a few different ways to remove an AR muzzle brake, but the most common and effective method is to use an impact wrench:
- You will need to remove the front sight post and gas block from the barrel.
- Locate the two screws that hold the muzzle brake in place and remove them using an impact wrench.
- Slide the muzzle brake off of the barrel and dispose of it properly.
You can use a vise and a tool called a barrel clamp. First, you’ll need to make sure that the vise is secure and won’t move around while you’re operating on the gun. Next, take the barrel clamp and line it up with the muzzle brake. Once it’s in place, simply tighten the clamp until the brake pops off.
If you don’t have access to a vise or barrel clamp, you can also try using two pipe wrenches. Place one wrench on the muzzle brake and another on the front of the barrel, then twist them in opposite directions until the brake unscrews. Be careful not to damage the barrel or muzzle brake in the process.
