Bought this for my 10.5” Pistol chambered in 7.62x39... Love the concussion it gave me for my other 10.5” Pistol chambered in 5.56.. Now I have TWINSIES

I have the same brake on a Ar-15 build, and the recoil reduction is hands-down one of the best I've experienced. So, I bought the 308 one as well. They work amazing. The 4/5 comes from the fact that it with kick dust all over you if you shoot from prone, or a dust base. I experienced this with the .223 model as well. Highly recommend hearing-pro as well as it kicks sound backwards as well.
Good for Target shooting
Keeps muzzle from lifting too much but the slots are angled back just enough where you feel the blowback on your face with every shot. And if you ever need to shoot without ear protection in a self defense situation you will have hearing damage.
Good brake for the money
Finish was good, a light gloss but not too bad. The brake threaded on just fine, but I had to shim the brake in order to torque the brake and line the top ports,no big deal. The gas ports do point rearward towards the shooter but this particular rifle is only for the range. The brake does what needs to,eliminates some of the recoil.
Be prepared for backblast
It certainly reduces the recoil at the cost of a major exfoliation of your face. I have one on my upper that was included in the purchase and will be replacing it. I shoot AK’s and .308 so am used to the kick of those.
<br>From PA: From PA: We have sold bunches of these with very few issues. It sounds like we may need to swap that out for you.

Perfect for what it is meant for reduced recoil and muzzle rise. Have one installed on a 556 AR 15 build as well as an AR 10 308 build works just as well if not better than my $100 comp I have on my Savage 10 BA stealth. In short yes it is loud yes gas blow back to right and left side if you don't have these on a comp it is not working right. Hence buy a muzzle break not a comp.
Good performance but with instal problems.
by Aaron -
Performance was very good but it has epic levels of backblast. I don't mind it, but kept being asked about it from the people next to me at the range. I would give it 4 stars for performance but knocked one off for installation. The threads on the comp only go half way down the hole and my barrel would bottom out with 1/4 inch of exposed thread. I had to use a clocking ring and a crush washer to cover the threads. The A2 that it replaced didn't have this issue.

I received my muzzle brake yesterday and installed it on my Bergara HMR. Honestly, I'm a little disappointed by the finish and crush washer. First, there was multiple imperfections on the muzzle brake like tooling marks, etc. Secondly the crush washer would not stay centered no mater what I did and end up causing the washer to not be usable. Thankfully I had left over washers from a previous muzzle device. I have not fired the rifle yet so I can't speak to the function right now but I plan on updating this one I do.
You can spend more on a brake, but it probably won't work any better.

This was my second brake. Now I own two of these.
<br>The first one I bought went on a brand new TC Compass in 308 Win. I didn't use the crush washer that came with the brake because the Compass doesn't have enough shoulder to take advantage of it. Instead, I used a thin lock nut that I bought off Amazon. I got the brake installed and indexed correctly and went to the range. The POI shifted slightly, but the Compass accuracy was unaffected - still under 1 moa. The brake worked so well that the effect on the recoil was such that I was able to see my bullet hit through the scope. I had never had that experience before.
<br>For the price, I don't think you can beat this brake with a stick. My first brake was a Vais on a 300 Win Mag. I don't think it works as well as this one for taming recoil. And the Vais costs a lot more.
What have you got to lose??
by Chris -
HOLY MOLEY! I bought this just because it was on sale for a ridiculous price. I put it on my 6.5 creedmoor Savage and it indexed perfectly without a crush washer or shim of any kind. Then I Shot about 40 rounds through it and couldn't believe the reduction in recoil, improved accuracy, and ability to spot my own hits (or misses)! I'm going to buy one of these every payday until all my threaded barrels are utilizing these brakes. They are great for my style of shooting.
Not pretty, but functions great
by Barney -
Break received with light surface rust in several places. Functionally this is great, visually it is flawed. Break also has a few scratches/tooling marks.
by Alex -
This works effectively at reducing recoil, not sure about muzzle rise. No problems with fit or finish. You will feel the warm blast coming back at your face every shot, which I don't get with other brakes. I have one on 3 of my rifles and one SBR. This brake is so effective at stopping recoil it creates a forward impulse in my SBR that is just enough to make the charging handle unlatch, due to the inertia of a heavier "tactical" CH latch. Never happened with a standard A2 hider, and a heavier CH latch spring fixed it, but I thought it was interesting. I'm probably gonna switch back to an A2 on the SBR just because it does throw so much blast directly backwards instead of to the sides like most brakes.
Zero recoil on my 16 RF 5.56 upper. this thing is awesome. Puts the brakes on all recoil!!!!!
Decent brake, horrible crush washer
by Austin -
The brake is good and manages to reduce felt recoil quite well. Mine was pretty free of imperfections but if you're trying to build a gucci gun I'd still say to steer clear of this brake. The big problem with this isn't the brake itself, but the crush washer itself. You might as well buy some crush washers, because the one that comes with this is horrible. The one I received was more of a normal washer with how flat it was. Impossible to get it in time. Would've been better not to include on at all and just tell people to buy their own.
This things works and it works well
This thing simply works very well. I have it on my 16 inch 300 blackout with carbine gas system. I shoot exclusively S&B 147gr ammo. The felt recoil is comparable or less than my AR-15 with 16 inch barrel and carbine gas system with A2 flash hider shooting heavy 77gr ammo. <br>Having said that, my 300 blk with this muzzle brake has slightly more felt recoil than 20 inch AR-15 with A2 flash hider shooting heavy 77gr ammo. But 20 inch barrel with rifle gas system is hard to beat in terms of recoil.
Great muzzle break, terrible crush washer
by Bryan -
I bought this for a 308 I was putting together, the muzzle brake is great quality and finish, a very matte black. Function wise it is very effective, but the crush washer it comes with is very anemic, I was lucky and only needed about a quarter turn left on it to time it after I hand tightened it, any more than that and I don't think the supplied crush washer would have been enough. If you are worried about it not timing on your rifle, be sure to buy a good crush washer to give it some extra room.
Decent muzzle brake
by David -
It definitely works. The finish and machining on mine looked quite good.
