Best .50 Beowulf Muzzle Brake - Editor's Choice

The bullet case is outfitted with a rebated rim, which size matches the 7.62×39mm and 6.5mm Grendel rounds’ rim. The dimensions of the case body resemble the .500 S&W Magnum revolver patron, but the .50 Beowulf is a bit longer and fully tapered for automatic firearm feeding.

Why do we need a .50 Beowulf muzzle brake?

The .50 Beowulf cartridge has the energy about five times and the weight about three times more than most 9mm rounds. A muzzle brake should be attached to the barrel (sometimes it can be an integral rifle part of the muzzle, cannon, or barrel construction as well); such devices are intended to redirect a portion of propelling gases to mitigate felt recoil, taking care of the shoulder, and prevent unwished muzzle rise, allowing to make faster follow-up shots and improve accuracy.

A crush washer is not included. While muzzle brake mounting it’s better to use a blue Loctite on the thread, backing up to right orientation, lock a locking set screw on the bottom, and keep a couple of days to set up.

How to install .50 Beowulf Muzzle Brake

  • Always before the .50 Beowulf muzzle brake installation or removal, unload the rifle; it must stay empty.
  • A recoil compensator, which is a separate unit, is easily mounted, but sometimes these devices can be integrated at the factory, becoming a rifle part of the muzzle, cannon, or barrel construction, so removal can take more time and effort.
  • If the factory muzzle brakes are attached by four Allen head screws around the brake, and additionally fixed with the Loctite, the bonding agent can be heated with a high-temp electric heat gun to simplify the removal.
  • Alexander Arms manufactures its own FF tube, compatible with the barrel nut (in case of tube replacement, it’s better to contact AA to provide proper fitment).
  • For the .50 Beowulf muzzle brake installation, use a locking ring and the barrel nut.
  • The actions will be the same as for all compensators mounting /dismounting.
  • Follow the instruction to reach due orientation: the muzzle brake ports should be perpendicular to the rifle vertical axis.
  • A crush washer makes the device timing easier and helps to line up it duly, although some muzzle brake types don’t require timing. This soft ring operates as a seal between the muzzle device and barrel, mounted without any tools, it’s necessary just to slip the washer on the barrel.
  • Tightening the muzzle brake with your hand tightly to the 10 o’clock (open-end wrenches can help), align the muzzle device with the barrel at 12 o’clock position (take the barrel face like a clock face). Then in short increments without over-tightening, turn the muzzle brake till getting the 12 o’clock position.
  • When the muzzle brake comes without a crush washer, then it’s recommended to use a couple of drops of blue Loctite on the thread, after that back up to due orientation, lock a locking set screw on the bottom, and give two days to set up.

My love of guns is in my blood, since childhood I have spent hours enjoying the beauty of guns and adored going through their parts.

Tactical accessories are another passion of mine that I could write about endlessly - my house and garage are full of tactical gadgets, luckily my family shares my interests.

I'm infatuated with traveling that's why work at one place with a daily routine and standard schedule is not for me. I prefer copywriting and English tutoring as a freelancer. I live in a male family among constant talks about cars, guns, hunting, fishing, and, of course, dinosaurs 😊.

My husband is an obsessed hunter, and my two sons are fans of «Demolition Ranch» of YouTube blogger Matt Carriker. They are my best consultants about weapon and all-around ammunition topics. All together we share a love for adventures. Every camping or mounting hiking trip is a "small survival", giving irreplaceable experiences. Nothing can be better than the satisfaction of observing wild nature.
