Our most patriotic brake, designed with quick American manufacturing in mind.  

All devices come standard with a free steel crush washer, but other locking options can be purchased to fit the build you're after.


MilSpec 416 Stainless, from a local supplier

3.3 Ounces

2.5" Length

.85" O.D.

.468" Thru hole, to fit a large variety of calibers. 

3 x .125" Comp holes, for vertical recoil reduction.

6 x .25" Brake ports, terminating slightly below the device's center-line to prevent prone dust up and maximize recoil reduction.

    Great Co. to work with! I sent a e-mail over a holiday weekend and Asked if I could get a 1776 made in 1/2 x 36 threads. I received a response in 1/2 a day! and they made me one within a week. They were not even offering that thread online yet. Great people! Now my 450 Bushmaster is complete.

    Happy Grendel & .450

    These brakes are perfection, I will definitely be buying more. You can’t beat the price or the quality I’ve referred them to all my shooter buds.

    It’s perfect!

    I built a 6.5 Grendel and was looking around for an affordable muzzle device. The Grendel like the 5.56 don’t have a kick so it doesn’t really matter what device reduced it. This one looks great and am SUPER happy with it!!! I’ve referred many friends to buy this one! There are others that they make that are different cool designs if this isn’t your style. The company’s customer service is good too! Can’t go wrong with heliustactical!!!!

    Outstanding Muzzle Brake

    Put this on my 300 blackout AR-15 at 30&100 meters holds perfect groups at those ranges. Easy installation will definitely be buying more of these in future builds.

    Beautiful brake that does an excellent job mitigating muzzle rise. Don't be fooled comparing this with other high priced brakes on the market; this thing is amazing and debunks the logic that you need to spend a lot to get a good brake.

    Amazing Company and Product

    Posted by Luke on May 21st 2018

    I bought this brake a couple of months ago while putting together a new build because it was on sale and had read great reviews about this company on reddit. Shipping was fast and the packaging was very well done to minimize damage. After installation I took it to a friends ranch and put about 200 rounds through it. I usually don't notice the recoil on an AR as it is pretty light but after putting this brake on it I can hardly feel anything. I would caution anyone standing next to you while shooting with this brake because they will feel it. I highly recommend this product and company and look forward to doing business with them in the future.

    Great Brake, one small issue

    Posted by Michael Herner on May 19th 2018

    I bought the brake for a friend and he absolutely loves it so far. It shoots and looks amazing especially considering the price paid. The only complaint he had was that when installing it with an Magpul AR wrench, the wrench slipped off and dug a few gashes in the brake. He said he wished the flats on the brake were machined out a bit better but we don't know if the wrench itself is in spec. Either way, he still loves it and I've definitely been impressed with it.
