Auxetik Muzzle Brake

Thanks to Alex Ko of KO-TAC for the video. He makes hitting steel that fast sound easy. Be sure to check out his company's custom IR patches here.

Bleeding Edge 3D Printed Tech

The world's first 3D printed muzzle brake was designed and crafted specifically for this new process. How else were we going to fit 2 complete expansions chambers into one tiny brake?

Less Bang, More Clang

Get the steel targets ringing instead of your ears. Our innovative side- and forward-angled port design was specifically designed to reduce the concussion typically encountered with muzzle brakes. The device works equally well on short (10.3in+) and standard-length barrels.

Bragging Rights? Check.

Several law enforcement and military reviewers have called the Auxetik the best overall performing muzzle brake ever tested. Our design reduces recoil, eliminates muzzle rise, and minimizes concussion.

8000 rounds and counting!

Our T&E examples have currently survived 8000+ rounds of semi- and fully-automatic firing with no performance degradation. The fully-dense, 100% Inconel superalloy construction lends itself to maximum durability for a lifetime of use. This material is as strong as steel and as corrosion resistant as titanium.

Unpaid / unsolicited reviews:

"In my opinion (subjectively) one of the flattest shooting brakes of its size...minimal muzzle movement which is at least en par with a multi-ported competition brake. VERY little side to side movement. Not the best for flash, but it's not designed for that." Alex Ko, KO-TAC

"The goods news is that there's nowhere near as much blast as a conventional brake, and there's a good degree of control. In the open, I was hard pressed to tell it from an unbraked 16-inch carbine..." Iain Harrison, Editor in Chief, RECOIL Magazine

"Neal sent me the prototype brake to try out, and I was very impressed. It worked as advertised, reducing felt recoil and muzzle climb more than the standard A2 flash hider...The real party trick of the brake, though, is the lack of a concussive blast coming from the ports. Traditional muzzle brakes produce a wave of exhaust gasses that annoy your neighbors at the shooting range, but Neal’s venting system redirects the gasses in such a way that there is no longer a concussion." -Nick Leghorn, writer, The Truth About Guns

"First off, I'll say that it is the best comp/brake I have ever used. There is no comparison at all...muzzle rise is practically non-existent and the felt recoil is just a very light push...the rifle stays on target very easily for follow up shots. Muzzle flash was not too much of an issue. The brake also did not feel too "blasty". It was fun to shoot and very smooth. I have used many different comp/brakes, and most of the popular ones at this time...and this is hands down the best I have ever used." DS11B on AR15.com

"Looking at the brake up close, I was very impressed...As the shooter, it's very effective, the muzzle doesn't move...The Auxetik muzzle brake was much more pleasant than most of the brakes I've stood near. Flash suppression was near perfect for every 4 out of 5 shots (Federal throws a few fireballs)...The Auxetik muzzle brake is probably the future as far as brakes and cans go...After shooting the Auxetik at an indoor range, it's the first brake I would consider for HD use." Dave L. on M4carbine.net

It's pronounced awg-zetik by most people. We don't mind if you call it "the 3D printed Sintercore brake."

Also: it's kind of flashy. It does look cool...we're not denying that. But, the fact is that muzzle brakes like the Auxetik don't hide the flash caused by burning projectile gases, and, instead, they harness those gases to reduce the gun's recoil. If you need to hide the flash, get a flash hider. Anybody selling a muzzle brake that actually hides the flash isn't really selling a good, recoil-reducing muzzle brake at all, in our very non-humble opinion.

Technical Details:

Length: 1.75in; Diameter: 0.86in; Weight: 2.7oz; A2 flash hider external dimensions. The Auxetik brake is fully 3D printed in actual, 100% dense Inconel metal. Inconel is a superalloy consisting primarily of nickel and chromium. After printing, the brake is precision machined to ensure the bore is concentric to the barrel threads and safe to use. The brake features a hybrid linear/transverse gas flow using two expansion chambers. 3D printed internal linear gas vents, a Sintercore innovation, allow an amount of gas to meter out of the first expansion chamber and flow forward into the second expansion chamber. This provides increased concussion control for operator comfort. In addition, the external, transverse vents are biased forward, presenting additional concussion control, similar to a conventional linear compensator. These features are "beyond the line of sight" where a machine tool could not cut them and also feature wall thicknesses below 0.010" (0.254mm) in key places. These features, produced without welding multiple components together, could not be made in a traditional machined, cast, or EDM'd part.
