NERO® Model 556: Hybrid Muzzle Brake & Compensator
Neutralizing Energy, Remain at Origin

We set off to create the ideal compensating muzzle brake by starting from a blank canvas. Our goal was to completely transform the recoil impulse of the AR-15 into a simple, soft rearward push with zero muzzle climb. Due to the NERO 556's performance characteristics, we highly recommend using a firm but neutral grip when firing (specifically - resist any instinct to pull down on the rifle anticipating muzzle rise).

To achieve our design goal of zero muzzle rise, we had to reject all design constraints and engineer the NERO 556 from the ground up using computational fluid dynamics and direct metal laser sintering (DMLS – also referred to as “3D printed metal”). Leveraging these cutting-edge technologies also allowed us to manufacture a device using Inconel, a nickel-chromium superalloy more at home in rockets and jet engines (learn more about Inconel here), all to produce a muzzle brake that had no peer. Whether combat or competition, the NERO 556 is designed to give you the absolute ideal level of controllability and speed.

Designed & Engineered to:

  • Reduce Recoil
  • Minimize Muzzle Climb
  • Manage Felt Concussion Relative to Traditional Muzzle Brakes

Additional Attributes:

  • Compatibility: AR-15 | IWI Tavor (in 5.56mm)
  • Threads: 1/2x28
  • Calibers: 5.56x45mm NATO | .223 Remington | .224 Valkyrie
  • Material: Inconel | Learn more about Inconel »
  • Overall length: Approx. 2.6 inches
  • Weight: 3.8 oz
  • Pre-drilled hole for pinning and welding to a 14.5” barrel
  • Coating: Ionbond DLC
  • Serialized for Quality Control
  • 1 Crush Washer Included

    I replaced the A2 birdcage with the Nero 556 on my Galil Ace. Completely changed the handling of the weapon. The Nero tames muzzle rise like no other muzzle device I've seen. It also dissipates backblast and does not punish people next to you shooting at the range. By redirecting the energy up instead of to the side, it allows to you make successive follow on shots and remain on target watching each bullet strike through the optic. I've been using this for two years now and can honestly state this is worth the price. Excellent product!

    Incredible Unit !!

    Between WDR website & Optics Planet website, I've ordered 10 of these Nero muzzle devices. 1 for my wife's build, 2 for other people's rifles I've built and 7 for my rifles. (Including 1 of the 7.62 NEROs for a 1941 M1 Garand) I am a true believer in how this thing works! Ultra-flat shooting, recoil comparable to a .22 Mag and incomparable for shooting pleasure. I do not find that the device gives off the concussion that some others have reported and no-one in the next firing lane has mentioned anything to me other than curiosity about the Nero and how I find them to work on my rifles. These things actually perform as Walker says they do, just do not try to anticipate any recoil or you will start pulling the muzzle down and your 2nd & 3rd shots will go in the dirt in front of your target! Just hold the rifle in a firm and neutral grip, let the Nero do its job of keeping the rifle on target and you do your part with smooth trigger pulls; then you will see those 2nd, 3rd & 4th shots staying on target and those follow-on shots will be faster than you had normally or pre-Nero!

    The last break you'll ever need...

    Until they somehow manage to improve on it! (I dont know how). Im running this thing on a 14.5 inch barrel and all I can say is when I fired the first shot, the second shot followed more quickly and naturally than any gun I've ever fired. The lack of recoil or rise was unbelievable. I actually had to check to make sure the bolt was fully closed. When you squeeze, the sight picture just blurs for an instant, and then you're back on target. Its simply perfect at being a muzzle brake. I'm a bit familiar with the physics used to design the NERO, as well as the manufacuring process. This brake has no doubt made all other brake designs obsolete. It is everything you can't do with simple stock removal/machining. The shapes inside are literally impossible to do on any scale of production without 3D laser sintering. The design itself wouldn't be possible without 3D computer modeling and fluid dynamics simulation. Its simply the first of the next generation of muzzle brakes...and maybe the last too. Probably not. :)

    I have used a multitude of brakes and very few had any appreciable gain... the NERO was completely different. While the 5.56 is not a heavy recoiling round, this virtually eliminates barrel rise and allows you to stay in the glass and at point of aim much easier. I would absolutely recommend this brake. As a gear nerd, how could you not buy this just because it is 3d printed Inconel? You won't be disappointed either way.

    Legit-ness.

    I'm just an old chunk of coal so dont take my word for it but by golly this thing shoots flat. Its no joke. 3d printed Inconel? Its wizardry, but it shoots flat.

    Absolutely amazing. It has zero bounce. It doesn't lift. The videos are accurate but it's great to feel in real life. Highly highly recommend it. Drew was great and took the time to talk to me about mine. This is a great product and I will buy more. If you are on the fence... do it! You won't be disappointed. It's a legit product and makes a great addition to your piece.

    Works great.

    This works great. By far the best muzzle device I own. I had a problem with my order that was completely my fault, WDR responded same day and fixed it for me. GREAT customer service.

    Mr

    Great product! Easy install, visible quality and feel. Brake does exactly as described - eliminates virtually all muzzle rise, stays right on target as advertised. Couldn't be happier with the product. Awesome to see advanced technology applications in material and design, perfect compliment for my IWI X95. Thank you!

    NERO 556

    I highly recommend the NERO 556, the difference in my muzzle rise is night and day. There’s almost zero rise.

    NERO 556

    First off, I do have one kink to mention about this... Installation did not work out with the provided crush washer for proper alignment, so I ended up going to a friend's gun shop to have this installed. (Thankfully, he did not charge me) This definitely gave me a sour taste off the bat prior to testing this on my AR-15, as I hoped everything would've been ready to rock right out of the box. Sob story aside, I finally was able to head out to the range to test this and all I can say is WOW! I'd compare the recoil closer to that of my .17 HMR rifle now. Muzzle rise is a thing of the past. I had a friend videotape me while I fired 7 shots downrange, and I cant help but watch the video over and over trying to find the slightest hint of muzzle rise off my 10.3" barrel. No issues staying on target while firing in succession. After about 160 rounds, my installation troubles were all but forgotten. This product did exactly what they said it was designed to do. Great product, Great Function, Great results!
