Solar Tactical posted this image on their Facebook page. It is another example of someone tucking a  muzzle brake behind a long handguard. As we have seen in other examples, the handguard does not do well with containing the concussive forces of the muzzle brake. Does anyone recognize the muzzle brake design and the keymod handguard?

      My immediate thought:

  • TheNotoriousIUD

    This should be called “banana peeling”.

    • ostiariusalpha

      Ooo, good’un! Or how about “ninja bananas?”

      • TheNotoriousIUD

        To be honest im a little surprised at the dramatic warping what with all the holes in the hand guard.

        • Darrell

          That’s what the shooter said.

        Bananja!!!!

  • Mattblum

    I don’t recognize either bit of hardware. I am also kind of boggled that anyone is really ignorant enough to do this. Where do they think the gasses that are rerouted to create the brake action are going?

    • Xanderbach

      It could be because they see people placing “blast can” style muzzle devices mostly behind rails, and then don’t realize blast cans project the muzzle blast forward.

      • Mattblum

        Sounds reasonable. I just would never have considered doing it. Then, what do I know?

    • J0shua

      I bet some of these people think they can diy what lvoa did with there fancy combo muzzle brake/handguard flash suppressor thingy.

  • Giolli Joker

    The muzzle brake looks like a Tromix, to me.
    SGP76 Tromix Rifle Shark Brake
    (According to Tromix’ website however there are Chinese counterfeits around)

  • QuadGMoto

    Flash hiders aren’t all that friendly to sand bags either.

    • Robert Michael Jr Cottell

      Done that

    • raz-0

      Nor backpacks, or the jacket bundled up inside said backpack.

      Not that I thought it was going to survive comp blast, I was just a tad naive about how close was too close. Lessons learned.

      • QuadGMoto

        My case was slightly different. I started with it clear of the sandbag. I just didn’t pay attention to the backwards drift as I fired. 😳😵

        • Baggy270

          .44 mag does a nice job on sandbag too with barrel cylinder gap….oops!

  • QuadGMoto

    That kinda looks like they SBR’d the barrel, but left the hand guard alone.

  • Rick O’Shay

    Don’t know about the handguard, but that looks an awful lot like the Juggernaut Tactical JuggerBrake.

  • Lee Attiny

    whatever, that guy now has a handguard with integral bipod legs on it. Thats a win.

    • Daakboom

      Actually that’s a new design of standoff for barricade shooting Lol

  • BillC

    Why is this still happening? If it happens to somebody, they deserve it.

    • Ethan

      Because 95% of gun owners do not spend all their free time on blogs and forums. I’d guess that number is lower for AR owners, maybe 80%? Either way, there’s a whole lot of people who own guns that don’t participate in the online community.

  • John

    Well NOW the rifle just looks UBER tactical! It’s got fangs!

  • xebat

    Again ? What the hell, didn’t one like this happen couple of weeks ago ?

    • Anon

      Yep, we’ve seen this idiocy before.

      • Rick O’Shay

        And we’ll continue to see idiocy like this in the future.

        • Anon

          Unfortunately.

          Hey! I wonder if I should make a 300 Win Mag AR with a handguard that goes past the barrel and put a muzzle break on it? I think it’s brilliant!

          • Anon

            *Brake

          • Blake

            naw, in this case, “break” is appropriate 🙂

          • Anon

            True.

          • ralph

            Or maybe in this case “break” is correct. At least pertaining to the handguard.

            OOps, already addressed

  • c4v3man

    I still don’t understand the physics behind this happening. I know you’re dealing with something around 50k+ psi with a standard rifle round, however I would assume once the round cleared the barrel that the force would be widely distributed enough to work it’s way through the holes in the handguard. Even with the brake concentrating the forces to the side, I simply have a hard time grasping “this force feel like less than someone punching you in the shoulder”, yet punching the handguard wouldn’t split it. Especially since it’s just gas, I would assume the gasses would simply go the path of least resistance and vent through the holes in the handguard. I suppose it’s related to the speed at which this occurs making the forces immense for a brief amount of time, just not long enough to make itself felt to the user.

    My question would be is it merely the brake concentrating the pressure off to the sides that’s the problem, or would a standard flash hider tucked behind a handguard have similar problems?

    • gordon

      That was your gun, huh?;-)

      • DIR911911 .

        lol

      • c4v3man

        That would be pretty hilarious, but no, I’ve seen far too many of these posts to ever make that mistake. I simply would love to see a visualization of a pressure flow simulation showing the forces in play here, as it simply doesn’t look like there should be a problem with this given large enough clearances and enough venting. Well besides the potential safety hazard of your hand being in front of the muzzle and taking the same pressures.

    • Stan

      Don’t under estimate the power in pressure. 5.56×45 has a max pressure of 55,000 psi while aluminum has a yield strength of around 35,000 psi (with heat treatment. Less if not). Adding the heat from firing doesn’t help the situation either. The pressure wave from firing won’t lazily find it way around the handguard. Its gonna smash into it like the Titanic into an iceberg and then deflect around. I strongly suspect the pressure the handguard sees is higher then its yield strength. After repeated firing, it will break in a classic case of fatigue failure.

      As for your question of how a force that barely pushes your shoulder could do such damage to aluminum the answer is that the max 55k psi at the chamber has been mitigated by a number of factors by the time its gets to you. Weight of the rifle, the recoil system absorbing some of the force (bolt group, recoil spring), and the larger surface area of the buttpad compared to the casehead of the cartridge all help reduce the force you feel

    • Blake

      Poke a bunch of holes in an inflated paper bag, hold the end shut, & give it a good smack.

      It’s just gas, but It still goes “bang”…

    • Bjørn Vermo

      The metal in the handguard will get rather soft when you heat it a little.

  • Sianmink

    You can get away with this with something like the illicitly-acquired Troy Claymore Brake I’ve got because it’s front-firing only, but I wouldn’t recommend it with anything else.

    The one on the rifle looks a lot like a Tromix Shark Brake.

  • MrFN

    Thats a CMMG handguard, and I’ve seen the brake but can’t remember it.

    Stupid… No, really that’s all I can say, why would you do this without a LVOA rail or something similar? Just stupid.

  • iksnilol

    MUZZLE BREAK!

      Well done Sir!

  • Evan

    Anyone who has ever shot next to someone with a muzzle brake ought to know better.

  • JP McGillicutty

    “But isn’t that what the holes in the handguard are for?”

    • John Yossarian

      Ha! Maybe it’s what the holes in your hand are for.

  • Texas-Roll-Over

    That is a chaos muzzle brake.

  • TexianPatriot

    Could also be a coitac muzzle brake.

  • Sasquatch

    Hmm

  • Bill

    So take an unneeded brake, with pointless toothy things, put it underneath a rail that you don’t really need to accessorize…sure, makes sense.

    • Budogunner

      There is exactly one case in which this is acceptable: when the flash hider or muzzle break is also a QD mount for a suppressor and you NEVER shoot unsuppressed.

      That is often done to get the length and width benefits of an integral while still being able to share the muzzle can between platforms.

    • Harold

      Typical action for what, 90% of gun owners? 90% of the folks I see @ shows and stores: typically white dudes between 20 and 40, are so cool they do stuff like this. Buy junk and make it tacit-cool. It could be that I live in caucasian neck beard country so I could be biased.

      • I’m ready when you all are

        Let me guess, only black lives matter supporter ?

        • Harold

          No sir bad guess. equal opportunity hater of unintelligent and lazy lower socioeconomic people of all races. Let me guess about you: suburban white guy?

          • I’m ready when you all are

            Enlightened Democrat ? You can’t be an open equal opportunity hater of unintelligent and lazy lower socioeconomic people of all races now days unless your nonwhite. Or do you believe the main stream news and other non truth groups about white privilege but your white so you hate yourself and go overboard acting like a race your not ? I’m proud to be the race I am without all the guilt. Yes white but more rural. A dumb white hick as you will no doubt say or maybe more like the man that keeps the brothers down in a false reality. I really don’t care and have said my peace so that’s all from me. Carry on.

  • Blake

    In Soviet California, muzzle breaks YOU!

    • Penciljockey

      Huh?

      • Ergo

        get on youtube and look for yakov smirnov

  • Blake

    I guess you have to call the metal bits on the front of your rifle a “handgouge” if they extend over the muzzle brake, ‘cuz they certainly ain’t “guarding” anything anymore…

  • jess

    is it just me or does the other handguard also look like its been muzzle broked… maybe it was on purpose?

  • Jay

    The last time i’ve seen this happen the handguard had keymod holes as well. Those keyholes, close together, with the cuts on the back, create a very predictable path of least resistance.

  • How dadgum stupid do you have to be? I have exactly zero sympathy for any of these idiots, every single time this happens it is happening to someone who absolutely deserves it.

  • Fox Hunter

    Lesson of the story, use linear compensators. They work, even inside the hand guards.

    • BRYCE WALKER

      Havent seen this happen to anyone running the Noveske Pig…

      • Harold

        The KX-3 or 5 are too expensive (over $50) for these types.

    • Mazryonh

      Do Linear Compensators actually reduce recoil rather than just throwing some of the firing flash and noise forward though?

      • Linear compensators work well on short barrels, where standard comps and even some “flast-hiders” throw giant fireballs.

        • Mazryonh

          Okay, I take it adding an LC to that kind of SBR just gives you a narrower fireball out the front.

          • Keeps the flash out of the sight line of the shooter, as well as reducing the “BOOM!”

      • Harold

        No they don’t reduce recoil, but change the pressure “signature” backwards instead of up/down/sideways. If the linear comp is well designed you’ll throw much more of the discharge from the explosion forward. See offerings from Black River Tactical and/or Custom Muzzle Brakes dot com.

        • Mazryonh

          Does the act of throwing the muzzle blast forwards like Linear Compensators actually help indoors then? The firing noise can still be pretty deafening as an echo, and Linear Compensators are generally used on shorter-barrelled rifles.

          • Harold

            It won’t peel the paint off your hallway walls like a brake will, but there is not any reduction in decibels. If there were a change in the overall level of sound it would no longer be a simple muzzle device, but according to the all knowing and all seeing Federal Government it would be a suppressor. Once it becomes a suppressor you have to fill out 17 forms and wait 17 months to use it so you don’t go crazy and kill members of the Federal Government.

          • Mazryonh

            Yep, throwing the noise forward like an LC would only helps if there’s nothing close enough to bounce it back at near-full strength.

          • 1911a145acp

            Fwd linear comps DO reduce the pressure on the shooter and therefore the percieved muzzle blast and PERCIEVED recoil for most shooters. Let’s be honest, 5.56mm in an AR or AK platform does not generate much recoil. In competition where winning or 2nd place my be seperated by tenths of a second, and the skill level of the competitor is such so as to glean a real andvantage, the tenths or hundredths of a second saved and accumulated over a course of fire is real. In the real world, in a defensive low light shooting scenario, the shooter would be FAR better served by an effective flash hider/ suppressor or fwd linear comp that pushed noise, pressure, muzzle blast and flash AWAY from the firer and towards the bad guy(s).TactiKool looking comps and muzzle brakes are just that- Kool looking. They create far more problems than they solve in the real world.

          • Mazryonh

            I still don’t understand how LCs reduce recoil (they’re just throwing the blast forwards, where was originally going to go anyway), but I’ll take your word for it. I was under the impression that LCs also help with muzzle climb as well.

            Some of the “tacticool” comps/flash hiders have optional blast diverter attachments that throw the blast forwards after it’s been diverted once, making something that looks very much like an LC. That might produce the same effect as a purpose-built LC too.

          • Baggy270

            A liner comp pushes the recoil straight into your shoulder and supposedly noise away from you. I found it was noisier and went back to the standard A2 flash hider on my SBR which will always be loud no matter what. Not allowed cans in Canada and our new Prime Minister will probably ban AR’s anyway. They just banned 25 round 10-22 mags up here.

          • Harold

            Yes if there is no wall in front of you for say 100′. If there is a wall I front of your bullet the sound will bounce off of that back to you. I fear you are looking for a solution in the wrong way. You need a silencer to shoot indoors. Sorry but that’s the only way to get at what you keep talking around.

  • Will

    So very many “Tacti-Cool” fools that don’t take the time to think through the modifications to their zombie killing equipment.

  • Christian Hedegaard-Schou

    This new fad of hiding the brake under the handguard is my favorite thing of all time.

    Warnings or not, I think its popularity will take care of itself 🙂

    Handguard is a CMMG keymod rail. Most likely the 15inch model

  • Penciljockey

    Idiots

  • BRYCE WALKER

    Looks like a CMMG rail.

  • Patrick ONeil

    Muzzle brakes are great!

    For making a loud weapon vastly louder.

    After trying 3 different types on my SA58 Fal, I never noted any meaningful reduction in recoil but it did AMAZING things to the volume level. Great thing if you want to disturb those around you trying to fire their own weapons.

  • wjkuleck

    My 16″ Fulton Armory Titan .308 has a brake that was briefly offered by Brownells. It completely eliminates muzzle rise; it’s uncanny to be able to watch the target whilst the bullet perforates it. Is it loud? Probably; but, behind the trigger, one does not notice excessive noise. I wish I could get a couple more of these Brownells-brand brakes, but alas, they were discontinued years ago 🙁 .

  • Okay, so even it the handguard hadn’t blown apart, wouldn’t it have gotten awfully HOT?

  • Anon. E Maus

    It looks like it’s screaming.

  • Mazryonh

    “Don’t cover up your muzzle brakes”?

    I remember how this blog has covered muzzle brakes with add-on blast diverters/shields to throw the redirected gas forwards, after having been redirected by the muzzle brake first. Sure, the resulting combination is usually clunkier than purpose-made Linear Compensators, but perhaps using a muzzle brake with an optional blast diverter/shield to throw the propellant gas forward again might have saved this person’s handguard, assuming the combo could have fit inside the handguard.

    So maybe a viable solution really is to cover up your muzzle brake, but with a blast diverter/shield or even a suppressor instead of a handguard.

  • kcshooter

    This is why most of mine wear Levang linear compensators. Not that I’d use handguards longer than the barrel anyway, but the forward comps really reduce concussive force and noise at the shooters ears by putting all that pressure and noise forward rather than outwardly. And I think they are still only like $30, which is nothing compared to some of the prices on muzzle devices.

    • Mike Lashewitz

      Suppressors should be legal period.

  • Matt Wilder

    Oddly enough, not uncommon. I’ve seen some AR pistols from the factory or as pre compiled kits or uppers that make this same mistake, even without people having to make the mistake for themselves. My AR pistol kit came with a rail longer than the handguard by 1/2-3/4 of an inch or so, but then again, it also came with a “noise forwarder.” Yes, haha, it’s exactly and as silly as it sounds, and has no gas porting to the sides; it’s basically just an extended large diameter tube screwed to the front (MUCH more basic than even a Krinkov style brake) but it works. However, I can see people easily making this mistake, seeing as so many have when building, and posting pictures when they’re done. When people cruise around looking for inspiration, they see someone else’s BEFORE it’s failed, and they think, “Gee, that looks cool, I want to do mine that way too,” having no real working knowledge of the pressures involved. Next thing you know, you lose your rail, or worse yet, your freakin’ hand. Gas pressure is a scary thing sometimes, especially concerning those whom have no idea what’s coming. After all, even just several hundred pounds per square inch can ruin your day.

  • kcshooter

    Soooo by your logic, I’m not supposed to have a suppressor as a form of protest? No. That’s just sour grapes. Get over it.
    Whine about it and don’t have a suppressor, or suck it up, pay it, and have a suppressor. Those are your options. Pay up or cry. Pick one.
    Just because you don’t have one doesn’t mean your somehow more in the fight than I am. You’re not.
