Most Helpful Positive Review Completely Absurd
This brake performs exactly as advertised. Recoil be gone, and very much gone it is. It's blast to shoot, pun fully intended. Loud, obnoxious, you probably don't need it, but you should absolutely have it. The only downside I could come up with is the gas that gets sent straight into your face, but ...

Most Helpful Negative Review Permanent hearing loss
I got this to lessen the recoil on my ar10. I shot 20 rounds before I put it on, so I could judge the difference. Shot another 20 rounds. The recoil was less, but the sound was a lot louder and my Walker Silencer hearing protection was inadequate to prevent permanent hearing loss. The muzzle blast i...

Best recoil mitigation there is

by Les, Verified Owner from GA, United States Written on November 23, 2025
This is by far the best recoil reduction mod you can add to a rifle…especially.308. Works well on 5.56 and 300blk as well. When shooting at an indoor range, there is a noticeable blast to your neighbors on either side…but the recoil reduction to the shooter is amazing.
Pros:
  • Superior recoil reduction
  • Quick followup shots
Cons:
  • side blast
Best Used for:
  • Outdoor shooting
Would recommend: Yes

Christensen Arms Fix

by Tire iron, Verified Owner from NV, United States Written on October 12, 2025
We’ve had many Christensen rifles come through our Long Range Classes and they wouldn’t group well. The fix was this M4-72 muzzle brake. These rifles would hold a .625 inch group or better.

Best buy I've made in a while!

by Thekingesq, Verified Owner from VA, United States Written on September 18, 2025
The Precision Armament M4-72 Severe-Duty Compensator is hands-down the best muzzle device I’ve ever used. Installation was simple, and once I got it on the rifle, the difference in performance was immediately noticeable. It does exactly what it’s designed to do—reduces recoil and muzzle rise to the point where staying on target during rapid fire feels effortless. Follow-up shots are quicker and more accurate, and the rifle just feels smoother to run overall.

While the side blast is definitely noticeable (as with most high-performance comps), it’s a tradeoff I’ll happily accept for the level of control this compensator provides. For me, it’s transformed the shooting experience into something much more enjoyable and precise. I highly recommend it to anyone who wants to push their rifle’s performance to the next level. 5 stars.

Perfect for a long barrel 5.56 build

by Mike G, Verified Owner from TX, United States Written on September 2, 2025
Works like a charm, part of a larger overall solution, but at the end of the day, my rifle has very little recoil and keeps my eye on target, as well as on subsequent rounds—very high quality. The only issue is the lineup. You'll need the shim kit to get it to tighten down and stay level. This part does not include the kit.
Pros:
  • Recoil absorption
Cons:
  • None
Best Used for:
  • Long barrels
  • Long Range / Precision
Would recommend: Yes

Great accessory

by Mike S, Verified Owner from FL, United States Written on August 21, 2025
The package was delivered on time and the product is exactly what was described. I've already been to the range twice and the difference it made is amazing! Little to no muzzle rise after install and the rifle sounds like a real beast now! Thanks Optics planet! You can't get a better compensator for that price.

Missing necessary part

by Dad, Verified Owner from CO, United States Written on August 14, 2025
Requires a special o-ring that is $25 and does not come with the part, nor is there a notification when purchasing that the part is required. The o-ring should come with the part when ordered or there should be a clear notification of this additional required part and its cost. The part effectively cost 25% more than I bargained for.
Pros:
  • Reduces recoil
Cons:
  • Missing part
Best Used for:
  • Recoil Reduction
Would recommend: No

Cons:
  • By standers will hate you
Best Used for:
  • Three gun faster follow ups
