The ArmaLite .50 Caliber Early Muzzle Brake The ArmaLite .50 Caliber Muzzle Break
The AR-50 is equipped with an extremely effective Muzzle Brake. It reduces the
punishing recoil of the .50BMG to a relatively mild shove. It is effective enough that
even a small-statured shooter can fire the rifle, and most shooters will be able to spend
long days at the range without discomfort.
The Muzzle Brake is held in place by both a lock ring and Loc-Tite. Don’t remove it
unless replacement or repair is necessary. Trying to force the Brake off without
softening the Loc-Tite may unscrew the barrel!
II. SAFETY FIRST:
Always wear effective hearing protection. The AR-50 is extremely loud due to the
efficiency of the muzzle brake. Wear double hearing protection: foam plugs and good
quality hearing protection muffs. Assure that spectators and other shooters within 100
yards of the firing point are also wearing hearing protection. You
are responsible for
warning them that you are about to fire, and that the shot will be loud.
Never fire the rifle without the Muzzle Brake in place. The Muzzle Brake is an
important safety device. It makes the rifle comfortable to shoot and, more importantly,
prevents the rifle from recoiling hard enough to possibly injure the shooter.
Assure that the Muzzle Brake is firmly secured and undamaged. Make sure the
Brake is screwed fully and firmly onto the Barrel. Make sure that all of the Brake Screws
(early brake) are in place and fully tightened. Never fire the rifle if a Screw is missing.
Never shoot the rifle without the Blast Deflector (the heavy wings behind the brake) in
place. Normal tolerances may allow the Deflector of the early brake to be slightly loose.
Make sure that your backstop is fully capable of stopping the powerful .50 BMG
cartridge.
Avoid muzzle blast. The AR-50’s Muzzle Brake works by diverting muzzle gasses
towards the rear. It is LOUD. Spectators should not stand within 25 yards of the Rifle,
and should be especially careful not to stand in the area 30 to 90 degrees to either side of
the Rifle. The best place to be is directly to the rear of the Rifle, shooting it.
