FREQUENTLY ASKED QUESTIONS
When selecting a caliber for one of our muzzle devices, the correct choice is based on your cartridge's actual bullet diameter. For example; if you have a .300 Win Mag, you would select a 7.62/.308 muzzle device. This is because the bullet for that cartridge is a .308" diameter. For a more detailed explanation and examples, check out our Caliber Fit Guide.
You can, we just don't really recommend it. Reverse-venting brakes do just that; vent gases in the reverse direction from where they were traveling. This design is how such high recoil reduction ratings are achieved. But because of that, gases and concussion are directed back to the shooter. Barrels below 14.5" can cause these forces to be quite drastic to some individuals, and more extreme depending on what caliber you are shooting. For a more detailed description, you can read our Muzzle Brake Safety Memo here.

Very happy with this product. Be sure to follow the instructions and use the recommended shims. At first I relied on local gunsmiths to install the brake for me and they used their own shims. This caused the accuracy to suffer greatly. Ended up overnighting the shims from precision Armament and reinstalling the brake myself. Shoots sub MOA with less recoil and looks awesome while doing it.
Great muzzle brake
I have used this device on my Savage 10 308 Win for precision shooting and it has done a fantastic job on recoil management and helping me maintain my reticle on target after each shot. Installation with the Accu-washer system took time but helped time it properly. The concussion and gas blowback is potent with this device but is a worthwhile trade-off considering how well it reduces the recoil impulse. I’m very happy I bought this device back in Sept 2017 and still have it as of now (2021).
I had this break installed on a TC venture in 300 win mag. Due to bike crash my neck and shoulder are damaged and even light caliber rifles were painful. My family had this break installed as a Christmas gift a few years back. My 300 in my favorite rifle now. I can sit through a 50 round prone session and that night I don’t even feel I had been shooting. I have shot other rifles with other breaks, none were 300 win mags and none are as soft as mine. Hands down if you want a break to control recoil at a price that doesn’t make you question a suppressor then this is the break for you. Purchased and installed by Liberty Firearms Institute Loveland CO in 2016
I purchased this brake based on all the reviews I found online. I have to agree, this is probably one of the most effective brakes I have ever used. The reduced recoil is great. The blow back towards the shooter was a little weird at first but I have become used to it . Some of the guys I shoot with complain about the noise but it was money well spent! I highly recommend this brake if you are looking at reducing recoil and speeding up your follow up shots.
If you are considering this brake. Don’t! Just BUY it. IMO there is no better! Sight reaquisition at 100 yards is absolutely no problem. Literally no muzzle rise on my 18” .223 and truly a pleasure to shoot. Just make your neighbors at the range tables aware because it sends quite a shock to both sides. I also purchased the M11 for my 6.5 Creedmoor and the muzzle remains flat. Just a great lateral shock.
I purchased this today 07/24/18. I did so because I had purchased one before and absolutely loved the reduced recoil. You’ll be hard pressed to find ANY compensator in the market to match the recoil reduction and quality of the M4-72. It’s simply the best in my opinion. One warning…when they say you may experience severe blowback, Precision Armament is not kidding. This bad boy is loud…really loud. It also sends a flash and blast signature to the sides that goes on for 2 weeks. LOL….But, I still love it. You may not like shooting it at an indoor range, but it’s fantastic.
