[GAO] R.A.G.E Tune-able Muzzle Brake

At the Great American Outdoor Show, in Harrisburg, PA, I came across UM Tactical. Somehow we missed this at SHOT Show. UM Tactical has a tune-able muzzle brake called R.A.G.E. (Rapid Adjustable Gas Expulsion). It retails for only $159.99. The RAGE conforms to 3Gun Nation and USPSA Multi-Gun rules so you should be able to use this in any division.

The RAGE brake comes with 5 port washers that you can mix and match to reduce recoil and muzzle climb. The washers are keyed to the muzzle brake. Depending on your preference you can rotate the washer 180 degrees before installing it onto the brake and close off the ports if you don’t need them.


In the photo below you can see the first washer side port is slightly off center to the subequent two behind it. That is done on purpose to mitigate the typical shot that tends to move up and to the right that most right handed shooters experience.



The numbers indicate the angle of the ports by how many degrees it is shifted.

Here is a video by Justin Winstead briefly explaining the RAGE and test firing it.


The RAGE comes in .223/5.56 and is available now. UM Tactical also makes the RAGE in .308 and 9mm but are not available on their website just yet.

    “Only $159.99” am I right in saying that you can get a well made AR for $800? If so I think it’s fair to say that a muzzle brake being worth 20% of a rifle is a wee bit expensive.

    That being said I also understand that it is not an ordinary one piece break and that it is aimed at the competition market.

    • iksnilol

      If you include sights you can get it up to 800.

      At least that’s my impression. A decent AR can be gotten for like 600 USD or something. Cheaper if you time it right.

      • raz-0

        It all depends on how you define decent. But even for some pretty nice set ups, $159 is steep just to have comp legos.

        • Dracon1201

          It’s not incredibly overpriced. Still cheaper than a Battlecomp, and this is very modular and tunable. I’m pretty sure these weren’t made with the people buying $500 S&W ARs in mind.

          • tts

            That doesn’t mean much though since the Battlecomp is insanely overpriced. You’re better off just getting something like those of those “tank” JP Recoil Eliminators.

            Precision Rifle Blog did a great test on a bunch of brakes and that thing was generally the best. Only downsides to it are looks and you can’t shroud it.

          • Dracon1201

            Agreed. There are better ones out there. Check out the TTAG tests, they compare a lot.

        • iksnilol

          159 is steep for any brake IMO.

          Decent = good, not “fry my nerves with pleasure”-good but good.

    The last time I sh-t up and to the right was in the bathroom on a bumpy flight from Boston to Houston.

    • JumpIf NotZero

      I don’t remeber the last time I saw an article without a typo or a error boarding on fallacy. Gotta hit that word count!

      This isn’t getting into the fact that every product gets a positive spin, even when it’s a giant, expensive, heavy, “tune-able” muzzle brake that very likely underperform me compared to established products.

      • TheNotoriousIUD

        I’m going to assume that the multiple grammatical errors in your post are intentional and sarcastic…

        • JumpIf NotZero

          iPhone, and I’m not a writer.

          • TheNotoriousIUD

            Fair enough.

            You still have not fessed up as to where you received your military (I assume from the way you talk) training.

          • JumpIf NotZero

            I have at no point said I was military. If you’d like to tell me where you are, I can try and find who a legit trainer is in your area, since I’ve trained around the country.

          • TheNotoriousIUD

            My question, very simply, is where did you receive your training?

          • JumpIf NotZero

            LOL, uh oh, some troll is calling me out! Uh oh! Tell you what, you find one thing I’ve posted in regards to technique or training you disagree with, and I’ll explain exactly where I learned it and why I think it’s legit. Writing out everywhere I’ve been isn’t going to “prove” to you anything…

            Honestly, you wouldn’t believe anything I wrote anyhow. So far as you’re concerned, believe whatever you like. But I’ll tell you something…

            Not everyone is as fragile as you are. You don’t take formal classes not because you don’t have the money (although you may not) it’s your ego. You couldn’t go to a class and be told you aren’t doing it right. You’ve been shooting for years! Right!? … I’ve seen it before. You’re projecting on to me bro.

            Edit: I’m still happy to point you in the right direction depending on where you live and how far you would travel.

          • TheNotoriousIUD

            Dude, calm yourself. Stop being so defensive.

            Im simply asking if you have ever been in the military or a LEO. Is that a terribly difficult question to answer?
            I mean if you say yes ill probably believe you, its not like its uncommon and I will never know for sure anyway.

          • iksnilol

            Why so jumpy?

            He just asked where you got your training? Like, would you be so defensive if I asked you what brand of rifle you use? Same thing really.

          • JK

            Guess I don’t have to shoot well, because I’m not using a target pistol, and I’m not a police officer.

      • Word counts?

        • JumpIf NotZero

          Oh I just assume that’s the reason for the degrading quality of the text added on to press releases. Someone trying to hit a word count or something.

          Otherwise, why would there be talk about topics like Sharia law on TFB?

          • BattleshipGrey

            I was thinking blogs get more money based on the number of readers they have on each article. I don’t think word counts have been a money maker since the first half of the 20th century.
