Introducing our revolutionary two-piece rifle muzzle brake, expertly designed and crafted after nearly two years of intensive research and development by champion shooters Kyle Litzie and Zack Smith.
Our innovative baffle design is specifically engineered to dramatically reduce rear recoil impulse, giving you the fastest and flattest shooting experience possible. The expansion chamber and high/low pressure ports allow for customizable muzzle direction movement, giving you the ability to tune out muzzle climb and direct just the right amount of gas in the right direction, providing you with a substantial advantage over your competition or enemy.
Our expansion chamber design adds dwell time to the gas system, creating a more reliable function, similar to the legendary Russian AK-74 muzzle brake. This unique feature frees up your body and mind, allowing you to focus on other shooting related tasks and gives you the consistency you need to excel.
Say goodbye to muscling your gun back on target and hello to a faster and more consistent shooting experience. Our unique two-piece design outperforms the competition and gives you the confidence you need to hit your target every time.
No expense is spared in the manufacturing of this brake. High quality American steel that is machined, heat treated, and coated in America by Americans. Finished with Physical Vapor Deposition (PVD).

When I installed this muzzle brake, I simply was like, “Imma leave every hole open, I probably dont need to tune it…”. Little did I know that every time I fired my rifle with the UB brake on (untuned) I was literally FIGHTING the rifle upwards because it was pushing the muzzle downward so hard that I was hitting D zone from the A zone with a double tap at 35 yds. But, after adding some small holes and closing some off, I couldn’t even force the muzzle to rise or fall when I was shooting. Dead on accurate!

This brake is ridiculous! I first put it on my AK47 which as everyone knows has some recoil. It made my AK shoot like my AR15. No muzzle rise and no recoil into the shoulder. before I would shoot 2-3 magazines of 7.62 because the recoil would dig into my shoulder, now I can shoot it all day. I was so impressed I put it on my AR15. Holy frijoles batman! It turned my AR15 into a 22. It does not move up at all. At 50 yards on an 8-inch target, you can shoot as fast as you can and all the rounds will impact on target and next to each other. It’s the best brake I have ever had. yes it’s $200, but a good brake from Jmac or Silencer co will be about 80-140 dollars. For a little more you get a lot better brake. You just can’t understand until you use it. Trust me, It is worth the extra money.

This brake is crazy awesome. I have it on my WBP AK and the recoil is almost nothing and stays on target for follow up shots. I’m so impressed with the brake. Well worth the money in IMO, I’m happy I made the purchase.

I was in the market for a 7.62×39 muzzle device for my gf5 PSA Moekov (Od green) and I couldn’t decide between this or a Jmac a well known competitor. I used a few references, one being ”Klayco47” who owns both. After much consideration I took my chances with Unrivaled and to be clear even my twink self can handle an Ak’s recoil fine but I wanted to make my setup into a laser and it did not disappoint……. even my local range was like and i quote ”This is the flattest shooting Ak I have ever experienced”. I’ve had a shit eating grin every time I’ve taken my Ak to the range, I highly recommend.
P.S: I was in no way shape or form paid for this review I only review products that I thoroughly use and enjoy.

After some minor tuning the “loudencer” , as I like to call it, will make your gun shoot flatter than Taylor swifts ass

I was so impressed with the unrivaled Dead blow buffer that I had to try the full kit. My unrivaled set up Rifle is by far the flattest and softest shooting AR-15 I have ever had the pleasure to run. Don’t hold back, get the buffer, get the UB brake, get the grip, get the titanium BCG. Just one thing..if you own more than 1 AR pattern rifle you will need these on all of them…you’ve been warned.
