LANTAC Dragon 9mm AR Muzzle Brake

lantac_dragon

LANTAC is working on a 9mm version of their popular Dragon muzzle brake. It will be made for 1/2-36 threads for 9mm ARs, not for handguns unfortunately. That would be pretty awesome though (see below). They’re available for pre-order at Revolvr.com at $124.99.

    Why?? 9mm AR don’t need it.

    • iksnilol

      Works as a decent thread protector I presume, though for that purpose it is way too expensive.

  • West

    Im thinking about purchasing a muzzle brake for my full auto XM177E1 but im uncertain about their effectiveness. Can anyone share their experience, good or bad, and suggest a specific brake?

    • G0rdon_Fr33man

      You just wanted to sneak into the conversation the fact that you have a full-auto rifle, didn´t you?

      • West

        Ha, no just thought that piece of info might be a factor in recommending one type of brake over another.
        But now that you mention it having a F/A rifle is pretty kick ass. Although I am currently trying to work out some kinks with jamming issues right now.

        • G0rdon_Fr33man

          I´m lucky enough to be issued a 416 which I get to keep at home, but I don´t own it myself. I know what you are talking about 😉

    • iksnilol

      I would recommend a suppressor over a brake.

      Brakes increase the noise, by about 10 db on average IIRC.

      • West

        I have a suppressor but have never used a brake to mitigate recoil ( its not much of an issue with a 5.56) but I have heard that they can offer you a little more control when firing full auto. Any truth to that?

        • iksnilol

          I would presume a brake would help. I mean, if it helps against muzzle rise on semi auto why wouldn’t it work on full auto aswell?

          But, a suppressor works better. it reduces recoil and it doesn’t damage your ears like brakes do (brakes increase sound by 10 db on average).

          • West

            Makes sense. I was just experimenting.
            Anyway I do most of my shooting indoors so even with a suppressor I still have to wear ear protection which kinda sucks.

          • iksnilol

            Yeah, but with a muzzle brake you will most likely damage your ears even with hearing protection. Also, I always recommend hearing protection if firing full auto, even when suppressed. Simply due to the length of the noise.

          • West

            Wow, thanks I had no idea a brake ramped up the noise to such a degree.

          • iksnilol

            I know the Finns tested it. They found muzzle brakes increase noise by 5-10 db for the shooter.

            The only advantage that brakes have is that they don’t affect the buildup of heat in a gun (nor do they increase the rate of fire). If you shoot suppressed then you know what I mean.

            That’s the link to an interesting and useful document. Here is a short summary (with bullet points or whatever they are called!): http://guns.connect.fi/rs/summary.html

    • That would be a short barrel without the crazy long flash-hider, right. So, linear compensator. I kinda like the Levang comp Otherwise, you are going to have some crazy muzzle flash and noise.

      1st pic is (discontinued, Battlecomp-style) PSA Pigsticker compensator. Second pic is the Levang comp.

      • West

        Cool thanks!

  • IXLR8

    Too bad. All of those pistols with threaded barrels, and nothing to put on them when the suppressor is not installed.

    I understand why you would want the 9mm carbine to have a different thread 1/2-36 to avoid putting a .223 flash suppressor on it. But why would you not offer it in 1/2-24, or 1/2-28 , since it would always be larger than the round it is attached to?

    Nevermind, I just saw the price. Good luck with that….

    • Cymond

      I’m planning to drill out an A1 flash hider as a thread protector for my 9mm threaded pistol barrel. We’ll see how it goes.

    • Plumbiphilious

      You can install a flash hider. Out of pistol length barrels, it does do pretty well for flash. Taking it off for a can is a different story though… I wish AAC had a QD 51T Blackout FH for 9mm/.45.

    • MR

      You’d think the price would be a deterrent, but you find quite a few muzzlebrakes in that range.

  • tts

    $125!? Even the high speed low drag mall ninjas are gonna balk at that price from a company that isn’t HK.

  • Plumbiphilious

    Does any 9mm load short of a 9mm rifle caliber need an entire dedicated brake?
    I can undestand a flash hider, but a brake seems excessive. A shooter probably benefits more from the added weight at the barrel end to combat muzzle rise than any recoil reduction from the brake redirecting 9mm’s meager gasses.

    • Mazryonh

      I would agree that the weight alone of a 9mm PCC (especially at the 16-inch barrel length mandated to avoid SBR legal issues) should mitigate the recoil pretty well alone by itself. Otherwise this muzzle brake might provide better control for those who are firing 9x19mm SMGs (like the MP5) for long bursts.

      • Bill

        I don’t know how often subguns are fired for “long bursts,” at least on purpose or not just to empty mags, but with the right technique all 30 rounds should be in one large ragged hole, brake or not.

        That looks like it was purpose-built to snag on gear.

        • Don

          I’ve got a LANTAC Dragon on my 5.56 and my .308 AR’s and I have never snagged them on anything, not even close. If you snag it on something you are doing something completely wrong.

          • Dan

            How would you rate it on the .308? Just curious, Im shopping around and and gathering as many opinions as possible

          • Don

            Hey Dan, it is as good on the .308 as it is on the 5.56. It has vertually no muzzle rise what so ever. But the people shooting next to you will hate you, it is definitely loud 🙂 🙂 🙂 It is the best muzzle brake that I have tried to date.

  • thedonn007

    I wish we could get rid of the 1/2-36 thread pitch and commonize to 1/2-28. Speaking of which, does anyone have a lead on a 16″ 1/2-28 threaded 9mm AR-15 barrel for sale?

    • AndyT

      Quarter circle 10 sells them. I’ve got a 5.5″ one on my sbr and it shoots pretty well

      • thedonn007

        Thanks for the suggestion. Now the question becomes, do I SBR my 9mm AR pistol, or do I build a rifle upper to be able to use a stock on my lower.

        • Don

          Get rid of the sissy 9mm crap that was made for handguns and get a real AR 🙂 🙂

    • It would seem that the problem is that some people aren’t smart enough to realize that a 9mm or .30cal bullet won’t go through a .224″ diameter hole.

      • thedonn007

        Yea, I could see that happening. However, I like to be able to swap a 9 mm suppressor between .22 lr and 9 mm fixed barrel firearms without having to switch the mount on the suppressor.

  • Mazryonh

    I know that Glock recently discontinued manufacturing compensated versions of its handguns, but compensated Glock barrels are still available through aftermarket manufacturers, so I don’t see much need for this on handguns.

    Still, has anyone made a version of a “linear compensator” for handguns? Those direct all the blast forwards while still providing felt recoil reduction.

  • El Duderino

    Tame that fierce 9mm recoil!

  • Budogunner

    Solution looking for a problem.

  • West

    Very informative, thank you.

  • Bill

    And that’s one of the reasons the 10mm MP5 made exactly zero friends – only the FBI would dream that up.

    For competition I suppose things like compensators are OK, but I dislike adding hardware to fighting guns to “solve” software problems that probably don’t exist in the first place. Unfortunately, for working guns, they do add bulk and noise, and I haven’t seen an analysis of the benefit versus the cost, both monetarily and practically. I could spend that money on training ammo and teach recoil management without an artificial aid. Both suppressors and flash-hiders add a degree of bulk, but they both have tangible real world benefits to compensate for that, pardon the pun.

    • Mazryonh

      Last I checked, the FBI is still using the MP5/10. What about it did you find unreasonable?

      And what do you mean “only the FBI would dream that up”? High-velocity SMG-type platforms have been made by the Russians (such as the PP-19 Bizon when loaded with their AP 9mm loading) recently. The FN P90 had its day in the sun, and manufacturers have even made very short carbines in 7.62mm NATO. Stuff like that isn’t hard to find.

      • Bill

        I haven’t seen an 10mm MP5 for I don’t know how long, and I’d love to know what happened to them. Even their own tests resulted in the FBI adopting the 5.56.

        Subguns become pointless when they become the same size as SBRs, but can’t match their performance. The 10 would never punch armor, whereas the P90 will.

        When pistol caliber subguns get larger than mini-Uzis and MP5 K/PDWs that just loose efficiency and practicality

        • Mazryonh

          SMGs didn’t start out as small as Mini Uzis or MP5K-PDWs. They got that small for specific applications.

          You need to check out the Russian version of the 9mm Parabellum round, which they’ve modified with a penetrator and a high-velocity loading to pierce up to Level IIIA body armour (i.e., anything that isn’t a rifle-grade plate), and also produced handguns and subguns to handle that kind of ammunition. That way, the Russians can use subguns (or even handguns) to penetrate up to that level of body armour.

          Compared to the FN P90 and the Five-seveN, the Russians’ conversion of a pistol round to an AP form means that they don’t have to use proprietary ammunition (which requires licensing costs). The 5.7x28mm round also has stopping power issues.

          No one’s ever tried to make an AP version of the 10mm Auto, but it shouldn’t be outrageously difficult given what the Russians have done with 9mm Para (and the 10mm Auto round would have more casing space to work with). And SBRs give off outrageous amounts of blast and flash every time they’re fired, wasting a lot of powder (because it doesn’t go towards increasing the velocity of the fired bullet). Besides, you can also share a subgun’s magazines and ammo with a companion sidearm. You can’t do that with an SBR in most cases. As for 10mm Auto platforms, this blog has covered a few new 10mm handguns lately.

          • Bill

            If I lived and worked in Russia I would. Granted, non-suppressed SBRs are raucous, but at least in the US they’ll hit harder, farther, in approximately the same size package. Ammo interchangeability has NEVER been an issue in a gunfight of which I’m aware, plenty of departments don’t even have a standardized handgun. My bean counters may like having fewer SKUs for ammo, but I want my handguns to hit hard, and my longer guns to hit harder.

            I don’t have anything against the 10mm per se, but I haven’t seen it having that much of an advantage over the .357 mag or SIG.
