Dead Air Armament’s Key-Mo Mounting System

Dead Air Armament’s recent announcement and release of the Key-Mo replacement mounting system for the SilencerCo Saker and Omega rifle suppressors is bound to ruffle some feathers. It’s no secret that the top men of Dead Air are former SilencerCo employees with little love lost between them. However, like it or not, there is room for improvement in SiCo’s MAAD mounting system, and the Key-Mo is designed to be a drop in solution.

Unfortunately, I have been a victim of the senseless stuck Saker syndrome (ok, that’s a bit dramatic). The mounting system itself is designed to be modular, with the ability to swap between different manufacturer’s muzzle attachments. The difficulty sometimes comes when using the MAAD system with SilencerCo’s own Trifecta muzzle devices – the silencer can be difficult to both attach and remove.

Built in two versions, the Key-Mo upgrades the Saker and Omega to use Dead Air’s brake and flash hider.

I’m not one to pick sides, but I’m considering an upgrade to the Dead Air system. As robust as the Saker is (I refer to it as an ‘end-of-the-world’ silencer), the intermittent issues I’ve had with the MAAD mount and trifecta flash hider have lead me to question the need for a quick detach system. Maybe the Key-Mo will revive my lost confidence.

I will post a review if I decide to make the switch.

    Very interesting. I’ve got an Omega, but I am not sure if I am a fan of the ASR mounting system. This merits investigation.

    “It’s no secret that the top men of Dead Air are former SilencerCo employees with little love lost between them.”

    I had no idea. Most of us don’t know the individuals involved in these companies, nor have time to follow all the vagaries of the industry. Just saying.

    When I first got my Saker, the mount was EXTREMELY tight. I placed the muzzle brake inside the mount to test out the locking lugs, and it got stuck. I didn’t want to mar the finish trying to take off the mount portion with the included wrench (believe me, I tried) so I finally went to Home Depot and bought a rubber strap wrench which worked beautifully, and I was able to separate everything.

    After browsing the Silencertalk forum, I bought a jar of Permatex Nickel Anti-Seize (#77124) which is the lubricant the experienced folks there recommend. I lightly coated the moving parts in the mount, and haven’t had any further problems. I really think it’s just due to the very tight tolerances, and emailed Silencerco recommending they lube the mounts before shipping to avoid frustrating first-time buyers like myself. I would recommend trying it Pete and see if it gives you any further problems after applying some anti-seize.

      Sorry, I’ve written about it a few times, but you’re right. I didn’t mean it as a “talk down” sort of way.

      http://www.thefirearmblog.com/blog/2016/06/24/mod-outfitters/

      I use the Nickle Anti Seize as well, but still have minor issues from time to time.

      Thanks Justin

    ruffle some feathers

    This is 0% different than the 51Tooth and YHM mounts SiCo has had for years letting their cans take different mounts.

    I don’t remeber industry disrupting from AAC or YHM, it would be pretty ridiculous to assume SiCo would even shrug at the same thing from deadair.

    If DeadAir had volume numbers in the wild this is product SiCo could make themselves. It still forces a SiCo can to be sold in order to use this product.

    • Pete – TFB Writer

      It’s 100% different.

      SiCo manufacturers those MAAD adapters for the AAC and YHM muzzle devices.

      Dead Air is manufacturing the MAAD module and the muzzle device.

      • JumpIf NotZero

        Ok… They’re making an adapter to fit someone else’s silencer to their own muzzle device where SiCo made adapters to fit their silencer to other muzzle devices.. Kind of opposite but the same… or you know, the same.

        “ruffle some feathers” could not possibly apply without hypocrisy on SiCo’s part.

        • Pete – TFB Writer

          The ruffle part has more to do with former SiCo employees making the mounts.

          • HSR47

            Actually, it might not ruffle any feathers: Silencerco already knows that there are problems with their ASR and Trifecta systems, and the public largely knows it too.

            Que Dead Air, stage left, with a new QD mounting solution for the Omega and Saker, which solves virtually all the problems with the mounting systems available for those mufflers.

            This makes the Saker and Omega MORE competitive, not less, and it doesn’t take much of anything out of Silencerco’s pocket. Sure, they may lose some accessory sales, but it keeps their customers happy. If they’re smart, and don’t want bad PR, they won’t take it badly.

  • Xtorin O’hern

    cuz ya know, gotta name that mounting system after a cancer treatment right?

    • Zach Robinson

      It’s the treatment for the Saker’s cancerous trifecta mounting system, so, yes.

      • HSR47

        ZING!

  • BillC

    It’s bot the MAAD system, it’s the ASR.

    • Pete – TFB Writer

      I mean the MAAD ASR module, but correct.

      • Drew Coleman

        Are they going to have a separate module for the omega? The Omega uses a different mounting module than the Saker series.

        • Pete – TFB Writer

          Correct two separate modules.

        • HSR47

          Yes. Dead Air is currently making two different adapters: One for Saker-series mufflers, and a different one for the Omega.

  • kalashnikev

    We don’t need more new mounting systems, we need more adapters for the existing designs. I would like to see a Griffin Optimus mount in ASR format.

  • KestrelBike

    The Omega was my first silencer and since I was on a budget of sorts, I didn’t buy more cans, but just outfitted many of my rifles with their ASR-system flash hiders (and one muzzle break for my 3-gun rifle). I probably have 6 of those mounts total.

    The system seems convenient, but the ASR mounts can be a pain in the butt because it’s definitely not foot proof. If you don’t properly tighten the silencer down, it can get loose on the muzzle device while shooting. When you sufficiently hand-tighten the silencer to the muzzle device, after shooting (and sometimes even not having shot the weapon, if there had been carbon-fouling on it) you need the wrench to remove the silencer for several reasons:

    1) the silencer body is very smooth and gets stupid-hot (obviously) after firing any caliber- this is not a design problem, it’s just physics. However, this means that it’s difficult to get any kind of grip-purchase to twist off the silencer if it’s got some carbon fouling, but maybe if you had one of those fancy rubber-like ovenmitts (that don’t melt) this could be done immediately after firing.

    a) the problem with this is that easily half the time that you manage to torque the silencer enough to defeat the carbon-stick (and I can do this after the silencer has sufficiently cooled, then I have to put the rifle between my legs and twist with both hands on the silencer body), what happens is that the silencer body comes loose from the silencer mount which still adheres to the muzzle device. I contacted SiCo about this and they told me to twist the silencer off from the knurled locking ring by hand. Well, that locking ring seems to be about .5cm of grip-width and my white-collar hands can’t do it most of the time.

    b) What I end up having to do is use the SiCo-supplied crescent wrench directly on the mount to torque it off the muzzle device. I end up laying the rifle on the range-bench, then having to lean my body-weight on the wrench until the silencer finally gives way to be able to twist it off. Being required to use that much force to get the mount off the muzzle device means that in the battle between tightness of connection in silencer/mount and mount/muzzle-device, silencer/mount will always lose, so I never go shooting without the wrench. Unless I’m doing something drastically wrong, I can confidently say that the ASR system leaves much to be desired.

    I wonder how much better this DeadAir Kymo system would be, but I’d be very wary of spending what I guess will end up being $200 for a mount + flash hider to try. Why don’t more companies utilize a system like the HK tri-lug mount, which doesn’t involve threads which can be fouled, but a lug-locking system?

    • HSR47

      The Dead Air mount system doesn’t involve threads on the muzzle device or inside the mount. On these adapters, there are threads to connect the mount to the can, and threads on the interface between the locking collar and the mount.

      I haven’t shot one, but I imagine that it won’t stick quite as badly as many other designs do.

      Personally, I have a few AAC 51T cans, and they occasionally get stuck on guns; When that happens, I usually just take them to the range and pop a few rounds through them: The heat (thermal expansion) and concussion tend to loosen things back up quite a bit.

  • Oaf

    Is no one going to mention how often Sakers launch down range?

    • HSR47

      They shouldn’t with this. The Dead Air mounting system has two sets of tabs that keep the can from coming off the muzzle device, and there’s no way to get it to tighten down without being properly indexed on the muzzle device.

      I’m getting ready to start paperwork on a Saker, and I’m going to get one of the Dead Air mounts for it next year, when I’m a bit closer to stamp day.

    • Dave D

      Other than the initial Saker demo, I haven’t heard problems with Sakers launching. I only used to hear the “launching” stories from AAC fanboys and doesn’t seem like their around much anymore.

  • AndyHasky

    Oh my god YES!

    • HSR47

      I know, right? This is totally awesome.

  • John

    I may have to get myself an Omega or two now.

  • JG

    I already picked one of these up. I didn’t realize until I got it that my Omega, one of the earlier ones doesn’t have any cut outs for the wrench on the end of it to tighten it down. so I have to tighten this by hand, and the cut outs for the wrench on the dead air module are not deep enough for me to get the wrench indexed with it (the wrench is too wide). I may send dead air an email asking them about it. I can’t get it tight enough by hand to keep the omega from threading off the mount when I go to remove the suppressor from the muzzle device… Kind of annoying, I may have to get 2 strap wrenches to get this thing tightened on there.

    • Rodney Backus

      My name is ROD BACKUS with Dead Air customer service i’m sorry to hear you’re having an issue with one of our products. I would like to get this issue resolved for you can you please contact me either by phone 435-783-9191 or by email Rodney.backus@deadairsilencets.com look forward to speaking with you soon

  • Dave D

    Don’t plan to make the switch until I run into problems with the MAAD mount or get a Dead Air can someday. Just hope they work out the disparate finish issues. The pics I’ve seen all have a huge finish difference between the new mount and the can. I’m guessing the finish would even out over use.

    Always good to have options and maybe someday I’ll end up with one over these.
