Hey guys. Josh Kent with U.S. Arms Company here on another video to talk to you about the M905 Talon muzzle brake. So the reason we’re bringing this short video clip to you about the brake is that we’ve had several people come onto our forum and ask about the brake, what makes it special, why should I buy it, which we’re all valid questions.

So we wanna talk through the brake, tell you it’s efficiency rating. We understand, you know, we’ve even had people say, well, is it loud? Um, that’s kind of a, I don’t wanna say, a redundant question, but all guns are loud. So yes, the brake is gonna be loud. That’s pressure coming out of the barrel that’s forcing the bullet out rear and up.

So yes it’s going to be a little bit louder than you would normally hear from a rifle with just a flash hider. I mean, guns are loud unless you’re running suppressed. And even then they have a certain decibel rating. The efficiency rating or effectiveness of the brake in every test that we’ve done has been around 94% reduction, and this is across all calibers, even up to the 50 browning machine gun round.

So out of a bolt action, which is all the testing that we’ve done, you can even shoot with the M905 on a 10 and a half inch, we’ve been able to shoot a 30 round magazine, one handed. And the weapon just sits still. So the brake is very effective in what it does in redirecting the gas mechanically up into the rear to keep the muzzle down and keep the gun almost pulling forward, away from you.

It’s very effective. So here we’re gonna talk about the design. When you buy an M905 brake, it’s gonna come in this box here. We have the brake pulled out right here. So this is one of the M905 brakes. When you get it, it comes with a pair of ear plugs, some assembly instructions for what we would show you as a torque setting even for the screws and then a shim kit to keep that alignment when you set it on the barrel so that it’s true on this line of bore because we have roughly two and a half inches of riding area where the bullet’s passing through this open channel.

In the brake that is. So you really want that thing to be aligned when you mount it to your rifle. Here we’re gonna go into talking about what makes it work. So as we see right here, the brake bisected here, we have a half 28 thread, which is your standard thread for AR 15. And then as we look, we have two different radius outside of the bore of the center bore line of this brake.

We have an inside radius and then we have a longer bearing surface or a longer radius on the leading edge. And the design was that as the gas exits the barrel and the bullet’s now traveling into this free open cavity, the the gas behind it would start to flow to the path of least resistance.

And so we see these longer arking radius to where the gas can now build. And then kind of slowed down as they get caught into these little pockets. So as the gas comes behind the bullet, it flows and it gets caught into these little pockets. And as you can see, this steep radius here is gonna speed it up.

And then the leading edge is gonna slow it down and grab the gas, the burnt powder, as it turns to gas into these little chambers. So what we have is a, a mechanical chamber on each side that’s now gonna slow down and hold that gas in this brake for an extended period of time, as would be your standard straight angle brakes, which is what everybody on the market is doing.

So we have a longer bearing surface and as we look to the exterior edges on the left and right, we have a vectoring or a closing off. Of where the gas is trying to escape. So most brakes, as we take a look at ’em, they had this large exiting area for the gas to bleed out and it’s not really focused.

And so here on our brake, as the gas is leaving, it’s somewhat focused down and compressed, allowing this gas to accelerate out of the brake and give it that much more efficiency of wanting to go forward away from the. And now we also look at these little pockets down here on the left and right edges.

So as the gas builds up it’s gonna want to come into this pocket right here, build up, and then by the slope of this cavity right here, it’s gonna want to direct it up into the rear. All right? And so now we have the, the gas exiting up into the rear of the. So we’re literally controlling the mechanical pressure that’s being released out of the rifle’s barrel up into the rear.

And you’ll see, we have done tests on these that it’s about a 60 degree throw to your left and right hand side. And what that does is that’s gonna pull that rifle away and not only pull it away, but kind of push that muzzle down and forward, which again makes the gun more comfortable to shoot for those who you know, if you’re kind of sensitive to recoil or if you’re a sharpshooter.

This is gonna keep you on target longer for PRS style shooters, this is allows you to shoot and spot your shot and that’s the whole reason behind the brake is to keep the shooter on target longer and make shooting more fun and enjoy. So the, again, the efficiency rating on the muzzle break from all of our testing has been 94% reduction in recoil, which we’re super happy with that.

We love the design. You know, a lot of people would say, oh, it’s, it’s a little bit bigger than what you know, we see on the market. Well, it had to be because we had to make the bearing surfaces longer, so it would hold the gas in those chambers. So again, we’re super proud of the M905 brake. We hope that you are too.

And again, thanks for tuning in to this channel, and we’ll see you again soon.
