Sons of Liberty Gun Works NOX Flash Hider


SOLGW NOX Flash Hider: The NOX Flash Hider is one of the top muzzle brake/ flash hiders on the market. Designed to reduce concussion while controlling both flash and muzzle rise. The NOX is also a suppressor mount for the Dead Air Sandman and Nomad suppressors. The NOX is designed for a right-handed shooter, pushing the rifle down and into the support (left) hand. The NOX can also be timed for a neutral or for a left-handed shooter position as well. This can be accomplished turning the device 45 or 90 degrees (respectively). The NOX will also bring 13.7” builds to a perfect 16” OAL when permanently affixed to the barrel (As per ATF instruction).

    Was running a PWS 5.56 comp on my 16 in rifle. Got tired of the huge fire ball and finally didn’t something about it. Did my research. Have high Respect for sage dynamics and gave a great review. So try it out. Was highly impressed. Flash was down to none, and with amazing sound reduction. Can tell massive recoil shing left handed, but the device is right handed timed. Might test neutral. Will update the review when I get my sandman out of jail.

    This is a premium part, use the Purebred 13.7 inch barrel with a good gas block and tube.

    Haven’t had the chance to shoot it yet but shipping was quick. Once received the fit and finish was great. I bought it for a 13.7 build that I plan on pin and welding. So i appreciate the the pin hold they pre-drill. Can’t wait for my sandman to get out of jail so i use the nox for what it was really meant for.

    The NOX is the real deal. If you plan to run suppressed, or you’d like to run suppressed eventually, this is the right muzzle device for you. Makes shooting indoors pleasant, offers some compensation, and gives you a great suppressor mounting platform for down the road. Double bonus, long enough to take your 13.7” muzzle device past 16” when pinned.

    Haven’t gotten a chance to shoot it yet but pinned to my 13.7 purebred its a bad mamma jamma (looks wise). Shipping was fast other than UPS regular BS.

    Looks fantastic, wish the ambidextrous version wasn’t released right after I bought it though. Haven’t shot it yet, but love everything about it so far.

    Super fast shipping and a great finisher for the 13.7” Barrels!

    Very fast shipping , looks amazing on my mk18 cant wait for my deadair sandman S to get outof jail 😅…………

  13. Conrad (verified owner)

    Heads up 13.7 is for 556 only. The 30 cal is for 13.9. The NOX also doesn’t fit the nomad. I think the NOX is great and Rosco is fantastic but I’m giving it 1 star for attention.

  14. Lyle

    Wish I’d read Conrad’s review before purchase. Does not fit with my Nomad. They should update their description, device doesn’t fit. I cannot get KeyMo to engage because device hits first baffle and cannot be tightened. Could not get through on CS number.

    Great product, can’t wait to install on my Rosco barrel!!

    I bought this SOLGW NOX Flash Hider specifically to go wth the 20″ Wylde Rosco barrel I used for my DMR build up. With a long tube there wouldn’t be much flash but I want to eliminate as much as possible so I installed the SOL version.
    I can tell you that not only does it eliminate ALL flash, but the downward impulse allowed me to watch the projectile strikes on the target as the optic never left the center of the POA. Yeah, these are worth every single penny regardless of barrel length so get you some. I’ll get more for EVERY new build and some of my older builds as well.

    Great company and products!

    Great look and fit for my build. Fast shipping

    Great quality device. It installed and timed easily with the provided shims. My sandman goes on and off well, and wear marks show that the bevel is seating/sealing well.
