Best 450 Bushmaster Muzzle Brake - Editor's Choice

A .450 Bushmaster is designed for hunting, an AR-15-friendly bullet, featuring down-range performance and energy. If you want to shoot down the game quickly, cleanly, and humanely at 200 to 300 yards, the .450 Bushmaster is the right choice. The best efficacy is reached firing from the barrel of a 16 inch to 20-inch length.

Why do we need 450 bushmaster muzzle brakes?

The 450 Bushmaster is more abusive with recoil than 350 Legend, so it’s better to have for such a rifle a good stopping power amount as a muzzle brake for comfort shooting. A recoil compensator minimizes muzzle rise, ensuring faster sights realignment on the target and issuing in better precision. While firing the round, the gases are redirected from the forward to the sides by the pressure of the burning powder out of the rifle muzzle, making the rearward propulsion weaker and the recoil is twice less, taking care of the shoulder as well.

How to Install a Muzzle Brake

  1. Unload the rifle, before the muzzle brake installation; it must stay empty.
  2. Check the information about the easiness of the muzzle device mounting and removal in the product guide, before buying one.
  3. Follow the manual to get proper orientation: the muzzle brake ports should be perpendicular to the vertical axis of the rifle.
  4. If you want to install a suppressor to the integrated attachment of the muzzle device, you should use duly sized shims.
  5. If you don’t attach a silencer directly to the muzzle brake, a crush washer makes the timing of the device easier, although some types don’t need timing.
  6. Models, which come with a crush washer, should have priority. This soft ring works as a seal between the barrel and muzzle device, and it mounts without any tools, it’s necessary just to slip the washer on the barrel. If there is no crush washer, then it’s possible to use a blue Loctite #242 (a couple of drops).
  7. Use a size crush washer or shim to line up the device properly. Perceive the barrel face like a clock face, the muzzle brake needs to be aligned with the barrel at 12 o’clock position.
  8. To install a crush washer or a shim, tighten the muzzle brake with your hand tightly to the 10 o’clock (open-end wrenches can be suitable as well). Then in short increments without over-tightening, turn the muzzle device till reaching the 12 o’clock position.

Zeroed rifles at 150 yards can have a rise of 1.8 inches at 100 yards, and a 4.9-inch expected drop at 200 yards. The .450 Bushmaster features a rather flat path out to 200 yards.
Does the 450 Bushmaster kick?
The .450 Bushmaster is constructed to operate in AR-15 rifles. The factory load spawns almost 23 ft lbs of recoil, and a full-power 12-gauge slug begets 45 ft lbs.


Muzzle brakes are worth purchasing, as they provide the rifle with less felt recoil, less upward and from side-to-side motions while shooting, quicker sights realignment on the target, and better accuracy. Withstanding the felt recoil, the muzzle device, attached to the rifle barrel, enlarges its length (consider that best 450 bushmaster performance at a 16–20-inch barrel length). These cartridges are compatible with a standard AR-15 magazine with a single-stack follower and should be stacked in a single row.

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.
