Hunting piggies by the dark of the silvery moon? Don’t want to blow your night vision with a plume of visual purple-frying burning powder? Strike Industries’ Venom flash hider has a fix for that. Deets after the jump . . .

Own one of the world’s most effective flash hiders! The SI VENOM FH nearly eliminates 100% of your muzzle flash and quickly disperse the burning gases exploding from the barrel. In return this gives you a faster follow up shots. The four prongs on the end of the brake are designed to protect the muzzle crown and gives this flash hider a one of a kind custom look! This flash hider will significantly reduces muzzle flash to help preserve your night vision. The SI VENOM FH requires no modifications to the rifle for installation. Recommended torque is 15-20 ft-lbs.

Edit by Jeremy S. — An SI Venom will appear in the forthcoming “AR-15 Muzzle Device Shootout,” along with 34 other muzzle brakes, comps, linear comps, and flash hiders. We also have two Venoms to give away as prizes for things like the Weekend Photo Caption Contest! For the record, yes, it does seem to eliminate flash completely, as you’ll see in the slow-mo footage, and was one of the few muzzle devices not to show some fire from the 5.56.

  1. The real question is, will it ring?
    All of the pronged muzzle devices seem to have a ringing ‘problem’. Not a huge deal but it would be interesting to know if the unique cuts on the outside of each prong reduce vibrations.

    • It does a little. You’ll be able to hear it in the video from the muzzle device shootout. The other one that went a little “tuning fork” on me was AAC’s Brakeout 2.0. It’ll depend a bit on barrel length and ammo choice and whatever else. Isn’t particularly loud or anything, but you can hear them ringing sometimes.

    • If you want a pronged flash hider that doesn’t ring, get the Seekins Precision flash hider. It was designed to be slightly asymmetrical, eliminating the tuning fork effect. I have one, and can confirm that there is no ringing and minimal muzzle flash.

  2. “The SI VENOM FH nearly eliminates 100% of your muzzle flash”

    ‘nearly’ and ‘100%’ are not synonymous.

    Kinda like ‘nearly pregnant’…

  3. I’ve been wanting to build an AK pistol from the moment I saw the Sig Brace online, but the added flamethrower effect was a concern. Cool as hell, but not something I particularly want out of my rifles. The .308 chamber break would work for a 7.62×39 round right?

    • Yes, but the muzzle thread size and pitch is an issue. Most AKs are threaded 14x1mm LH and most AR-10 and other… let’s call them “U.S.”… .308s are threaded 5/8×24 (inches), which is what the Venom is threaded for. There are adapters available if necessary. SI does make a decent amount of AK stuff so maybe they’ll do an AK version of this eventually. There are (or have been) also some AKs made for the U.S. market threaded 5/8×24 but none of the brands come to mind at the moment, but if you’re truly building an AK pistol you could definitely get a barrel threaded that way for your build. It would open up your muzzle device options in a really big way.

  4. This forthcoming ar15 muzzle device shootout sounds interesting. Is TTAG performing the test?

    Would be nice to see a test across a variety of muzzle devices used across a variety of ammunition types/brands across a variety of barrel lengths.

    • Honestly… gathering 35 muzzle devices, creating a recoil-measuring sled, doing multiple shots for each brake (110 rounds of American Eagle 5.56 for all of that testing plus creating strong baselines with bare muzzle and A2 birdcage plus repeating bare muzzle at the end to ensure everything had stayed consistent), entering all of the data into excel to sort everything, create averages, find the extreme spreads and standard deviation info, generate tables and graphs (NotoriousAPP helped by creating some nice charts!), edit all of the video from two cameras together, take & edit photos of all of the brakes, measure them all for weight and length and diameter, then write all of this up and include my thoughts on machining and finish and design, etc etc, has been a fairly massive endeavor. I’m about 1/3 of the way through writing up the article — all of those other things are done — and hopefully I can finish it today (Sunday) for publishing early this coming week.

      It would be cool to have shot them all with a different type of ammo and done the entire test again through a different barrel length, but the level of effort is pretty darn big already and 110 rnds of 5.56 plus the other costs ain’t cheap. Yes, it was fun! …At least the shooting part was haha.

  5. Jeremy S
    Would this be useful in AR pistols (11.5″)? I get that it’s main function is flash-hiding, but if the flash is hidden then the resulting report should also be diminished, right? I currently have a brake that supposedly angles the report forward, but consequently turns the barrel into a flame-thrower. I’m primarily looking for a non-ATF supressor.
    PS- was just checking out your ultimate mosin build, coincidence!

    • What you’re really looking for is a linear compensator. There are two from HERA Arms and one from Black River Tactical in this upcoming “shootout” thing, plus there are quite a few other options on the market.

      The test will also include the FERFRANS modular brake with CRD (concussion reduction device), but I can tell you now (spoiler alert 😉 ) that it definitely isn’t going to solve your flame thrower issue. At least not with FERFRANS’ 3-port brake inside of the CRD… and since I’ve said that I’ll also “leak” the fact that the CRD fits on other muzzle devices from other brands, one of which happens to be the Strike Industries Venom FH.

    • Went to the youtubes, and found a comparison. The very first was the Vortex. I could see no difference between the two. Comes in about 0:45

      • I have a Vortex as well, and I see no diff at all between the two. The only thing the Vortex is missing is support for a QD suppressor…

  6. Seems that they have failed to learn from history when designing this rifle part! I view every weapon I own as a tool that may be needed in real combat. Wether that be in a gun fight with a criminal, or with an agent of a tyrannical government. That battle could take place anywhere, including a wooded area or a tropical “jungle like” environment. Research the evolution of the original Stoner M16 flash suppressor and you will find he also had a multi-prong design. This ended up redesigned with an outer ring added to the tip to prevent the foliage of shrubs and bushes from getting lodged in the prongs while trekking through the jungles of Vietnam. Can you imagine stumbling into an ambush and having to take time to pull the twigs out of the end of your weapon before engaging the enemy? Ask the oldest of the Vietnam Vets what that was like.

    • You realize that is such a small problem right. Socom currently uses the Socom flash suppressor these days. And that is a open prong design. I have used it in the jungle and it wasn’t a issue. If you got a twig stuck in it, just shoot it. And if you really are worried about patrolling with it, just tape it up.

    • Actually Gordon, that was the reason provided in the official report, but if you do a bit more digging into the history of the change, the reason for the switch was because GIs were using their pronged flash hiders as prybars to open heavy-duty crates, which bent the flash hiders.

  7. This may be a dumb question but my wife and I are new when it comes to night vision. What we are wondering is when using night vision is it necessary to use flash supression I’m shooting a stag m4 with a factory suppressor she’s shooting a remington model 742 woods master that doesn’t have a suppressor will we need to change mine on my m4 and install one if possible on the remington.
