Shadow Valley Weapons SVCOMP



Here’s an AR15 compensator that I’ve never seen before, I recently stumbled upon the SVCOMP from the folks at Shadow Valley Weapons. It reduces muzzle rise and recoil like most other muzzle brakes on the market but has a few other features that others don’t. It has what Shadow Valley Weapons calls a 12 O’clock port void (no chambers/openings on top) to avoid muzzle flash from interfering with the shooters sight picture.┬áThe SVCOMP also has a glass breaking point at the tip as well as a wire cutting channel. It’s currently available in 5.56 with .308 and 300 BLK options coming soon. It retails for $85 at Check it out in action below.

CAL: 0.223″
OAL: 2.25″
DIA: 0.850″

    Actually kind of interesting. I’d like to see this go up against some of the other popular compensators.

  • Duray

    What makes it an “AR-15 compensator?” Wouldn’t it fit any barrel with suitable that’s?

    • Duray


    • Dracon1201

      Yes. But considering those threads are almost only on ARs and some bolt guns. You might as well appeal to your largest customer base.

  • Jack Morris

    I’m sure there is a valid reason for not just shooting the glass out if you need to break glass while holding a rifle. Could anyone help me out here?

    • Dr Sick

      Arresting people inside ?

      • Vitsaus

        Not with the current shoot first arrest later policy we’re seeing so frequently.

    • sam

      Yep, a reason that comes to mind would be in order to still be able to break the glass even if the glass does not happen to be in front of some other thing or things that one wants to shoot or is ambivalent about shooting.

      Also if one has to do a number on a piece of glass, one may well not be in a shooting range or a large secluded open space, therefore touching off a round may result in people being upset, questioning, fines, being forced to wear a punitive clothing item, etc.

      • Dracon1201

        Agreed, however, shoving an AR15 through someone’s window does also tend to draw unwanted attention.

        • sam

          Yeah, I should have said maybe increased tendency for people being upset, over the already high tendency of it happening due to holding a gun and breaking a window.

  • Joe Liberty

    Did he really just shoot that wire? Wow. That does not seem smart.

    • Esh325

      Definitely a certified mall ninja accessory.

    • lucusloc

      There has to be a better way to do that. Like wire cutters. Probably faster too.

      • Squirreltakular

        For speed, I bet wire cutters are faster. Add in a shop towel or something similar and it’s quieter, too. Much, much quieter.

        • lucusloc

          Yep, and while you may not be ably to keep your hands on your weapon with that method, you can keep your eyes open, which is just as important (did anyone else cringe like the shooter did when he pulled the trigger? I know I did. . . ).

        • Cal S.

          This is why I carry an old-fashioned bayonet with wire-cutting scabbard.

    • Rob

      Im sitting here thinking…..what about being sneaky thats usually why folks bother with cutting wire….if they need to go fast they usually throw a massive charge that blows everything up for 10 feet

      • Rooftop Voter

        Or throw a massive person over the wire and everyone steps on him to get through.

    • Pure STG58 style.

    • Zebra Dun

      It was taught at one time with M-14 and M-16 rifles.

  • Esh325

    Honestly, with all these muzzle brakes on the market it gets to the point where they have to come up with gimmicks because their brakes don’t offer any new recoil controlling abilities over the brakes on the market. The first two videos are pretty contradictory. He’s saying the brake is so controllable that an AR SBR can be shot with one hand on full auto, but in the second video he has a longer and heavier 16 inch AR15 and has such an aggressive stance and hand on the rifle you would think he’s shooting an M14 in fully automatic.

  • John Yossarian

    And this device can also be used to perform Se7en’s “Lust” murder?

    • Mystick

      Was that the one with the…. “device”…. with straps?

      • John Yossarian

        Yes – It’s the first image when you Google “lust se7en”.

        And that’s what popped into my mind when I saw this vicious shwanz of a muzzle brake. Give me a break with the brakes!

  • Vitsaus

    No one’s gonna say it? This is just an AK slant brake with holes in and sexied up with sharp edges.

    • Cal S.

      With about 45 degrees less slant?

  • Drapetomanius

    This looks like a reasonably effective muzzle device. I would pay as much as $35 for such a device.

  • Uniform223

    looks highspeed low drag. still prefer a flash hider though.

  • USMC03Vet

    Finally a muzzle device I can use to open all of these coconuts I bring with me during my ops.

    • Uniform223

      coconuts are a good source of hydration and nutrition. after said coconut is used as food. coconut hollow empty coconut shell can be used as blunt instrument against OPFOR. When cut in half coconut can be used as highspeed field expedient container for food. When worn upon head, coconut can stop low velocity hand thrown ballistic devices. The coconut is a highspeed operators best friend.

      • Tassiebush

        Coconut halves can also be used as deception device to mimic cavalry sounds.

        • Uniform223

          Monty Python Search for the Holy Grail reference… win

          • Tassiebush

            Thanks! It also occurred to me that they could be used as part of a cunning disguise when used with women’s clothing.

    • Zebra Dun

      Coconuts are a natural laxative.

  • Cal S.

    Yawn. Call me when they integrate a full-length bayonet and wi-fi booster.

    Honestly, though, if you’re going to carry this rifle in any kid of slide-in carry system, it’s just going to get torn to shreds with that glass-breaker point. I have a YHM breacher muzzle comp and that’s hard enough.

  • hami

    I have a feeling glass will break if I smash it with the muzzle of my rifle too

  • Spencerhut

    It’s a modified Spikes which is a cheaper version of a Battlecomp. I’ll be glad when the “Comp Wars” are over.

  • morokko

    I strongly suspect that real purpose of
    all those accessories is to boost sales of gloves. I suspect some clandestine cartels at work. When you mount all these spikey muzzle brakes, quadrails and grips with enhanced stipling there is no way to hold the rifle with bare hand without shedding your own blood. And simple gloves wont do, because all those vital accessories are Mil-Spec, outfitted with tritium inserts and made of scandium, titanium or space age proprietary polymer. Hence the gloves have to be tactical, reinforced and heat resistant. To think that people were once annoyed by sharp edges on plain AK…

    • iksnilol

      Kalash has sharp edges? That’s news to me.

      • John Yossarian

        I’ve been pinched pretty bad by a safety lever once or twice – Enough to wear gloves now if I’m running one heavy enough.

  • Zebra Dun

    Back in the old days we young bucks was taught to cut wire with a bullet and regular flash suppressors, hard to get the wire to sit still while shooting it though.

  • Judas Priest

    I’m sold. Where do I get it.
