Installing a muzzlebrake on an Air Rifle

A Muzzlebrake Can Improve The Appearance And Performance Of Your Air Gun

On air guns what we call a muzzlebrake doesn’t perform the same recoil-reducing function that it does on a firearm. The airgun muzzlebrake actually a barrel weight which also improves the appearance of airguns while forming a comfortable cocking handle on barrel-break air guns. It also performs an important function by covering the grooves left after removing the front sight.

Some air gun muzzlebrakes, like the Beeman Crow Magnum-style are designed to fit a specific barrel diameter without using sleeves or adaptors. It would seem that, once the front sight is removed, they would just slip into place to be locked with the set screw(s). This, however, is most often not the case. The ‘ridges’ raised when creating the dovetail for the front sight increase the diameter at that point and prevent the muzzlebrake from just sliding on. The wrong solution is to use brute force and hammer on the muzzle brake until it slides on. Not a good idea.

The suggested method requires only a few gentle strokes with a fine-toothed file to reduce the raised edges of the dovetail until the muzzle-brake slides into place without requiring a great deal of force. Use care to avoid scratching the surrounding bluing by masking the appropriate areas with tape during the filing operations. Slide the air gun muzzlebrake on, with the setscrews rotated to the bottom of the barrel — it may be difficult to rotate the muzzlebrake later if the fit is a bit snug.

Once seated to it’s proper depth, it is a simple matter of tightening the setscrew(s) on the air gun muzzlebrake to secure it to the barrel.

Don’t neglect to put that front sight where you’ll be able to find it – if you ever want to re-install it.

Check the muzzle-brake occasionally — especially during the first few shooting sessions — to make sure it is still securely fastened.
