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.

M4-72 Severe Duty Compensator
Just wanted to give the Guys/Gals at Precision Armament a shout out! I am a licensed Gunsmith and I've had a lot of customers coming to me wanting muzzle brakes installed. Most of the time the customer has no direction for what brand/model of brake they should use. I always tell I can only attest to the brakes I personally use on my own weapons. "Several years ago I came across the M11 brake from Precision Armament and it takes my .338 RUM's recoil down to a level that my 10 year old daughter shoots it with ease, since then I've used nothing but Precision Armament's muzzle brakes!" Recently I've been installing the M4-72 brakes on customer's rifles and the customer couldn't be happier. They (customers) always reach back out to me ecstatic , "Man, I wish I put one of these on years ago". I just smile and nod my head yes. Long story short, I will be a lifetime customer of Precision Armament and I can only suspect my customers will do the same. Great brakes, great prices, and their customer service department is phenomenal.

Best Fit and Finish
These not only look great they are just as functional. Significant recoil reduction with out degrading accuracy. Just wishing for a 6mm version using 6.5 now would like tighter bore to bullet diameter and the larger diameter of of the 5/8 24 in 1/2-28 for a seamless fit on bull barrel 22 caliber.

Recoil management
Shooting with the hyper tap on is like night and day. My recoil has significantly decreased, increasing my accuracy tenfold. The guys at precision armament are also fantastic. Easy to reach out to and extremely helpful and genuine.

M4-72 SEVERE-DUTY® COMPENSATOR
Bought the M4-72 for my AR-10 because the recoil was just too much for me (old man with a bad shoulder). It worked so good, I bought one for my older brother.

M4-72
Approximately eighteen months ago, I procured a muzzle brake to subdue my Bergara B14 chambered in 300 Winchester Magnum. After having it installed for some time and discharging several rounds, I felt compelled to express my utter satisfaction with its performance. The highly effective device has vastly diminished the felt recoil of my weapon, making shooting sessions a delightful endeavor. As I age, the onset of joint inflammation in my shoulder has considerably undermined my physical ability. However, the said muzzle brake has mitigated this issue and allows me to discharge rounds without any undue discomfort or impediments.

Purchased based on YT review
I was looking for the best muzzle brake to reduce recoil on my AR-15 as much as possible. I resorted to YT, and someone used a sled to demonstrate various brakes. This one had the most reduction in recoil, so I looked it up here and bought it. It is amazing. The barrel doesn't seem to move the slightest even when rapid firing. The blowback will knock your hat off (sarcasm here), and make sure your hearing protection is on. It is definitely louder than anything I have on my other AR builds. But it is worth it, in my opinion.

50%+ Recoil Reduction
Thier claim of huge recoil reduction is 100% true, I was stunned. People behind you to your right or left won't like it, but that's okay. ?
