I had the Keymo module get super stuck on muzzle devices a handful of times after high round counts and letting everything cool before removing. Think that’s the only suppressor mount I’ve had to clean, though. Quick squirt of CLP, 2-3 minute soak, then a wire brush for 30-60 seconds fixed the issue. I had a Plan A get a bit difficult to start threading on after about 4Kish rounds on my 11.5” SBR with no cleaning. How do you think ASR compares to the Griffin Plan A stuff?Īre any of these systems any more or less prone to carbon fouling?

With any mount the blast chamber depth, mount length, and muzzle device length have to fit. Which kind of side steps the utility of a modular back end. It may or may not be a good fit but people tend to buy into one family & stick with it. Keymo sells because of good PR and an army of gumbies talked it up, bought it up, and DA sells a shit ton of cans creating aftermarket support to meet demand when Dead Air can’t. In most cases a good flash hider is fine, the stellite blast baffle on the Omega is quite durable.
#Keymo alternative application series
Miwa Lock's electric lock iEL FeliCa, FKL series can be locked. If you don’t like ASR then Xeno, Griffin Plan A (multiple mount lengths & huge muzzle device selection), or Rearden Atlas/muzzle devices are lighter, less expensive, mostly shorter, more versatile options. KEYMO is an application for moving the key data in a card or tag used as a key to a smartphone and using the smartphone as a key. Tighten by suppressor body, loosen by mount body/ring. Works best with Dead Air’s cans with welded keymount.ĪSR requires making sure it’s fully threaded and collar locked.

And with a thread in keymount there’s a risk of the mount unthreading. Keymo makes it longer and heavier for the purpose of dumbly tucking a suppressor into a handguard. There were just a few random combinations people noticed that happened to work without using the QD Adapter Ring.You bought a short (with flat front cap added), relatively light suppressor. Regardless of all that, the easiest thing to remember is that all KeyMos from Gen 1 through Gen 3 regardless of KeyMo muzzle device choice (and all other 1.375x24 Omega pattern QD mounts) fit the Helios QD no problem when you use the QD Adapter Ring. Gen 3 KM (does not fit without using QD Adapter Ring) Gen 2 KM (fits without using QD Adapter Ring) Gen 1 KM (does not fit without using QD Adapter Ring)

Here are some pictures of the different KeyMo generations: As an example, people that had thread fitment inssues with the Gen 2 KM (which fit) sent their Gen 2 KM back to Dead Air to be replaced/fixed, but they were then sent the Gen 3 KM (which didn't fit) as a replacement for the Gen 2 KM because the Gen 2 KM was no longer being made at that time, so when they tried to assemble the Gen 3 KM and saw it didn't shoulder up in the Helios QD they were confused. What I wrote about on r/NFA was in response to peoples concerns about KeyMo fitment issues due to the different versions of KeyMo that were being released. The newest KeyMo mount (which I'll call Gen 3 KM) had ~.05" of material added back in front of the threads, and that extra material prevents the KeyMo from shouldering in the Helios QD because that extra material bottoms out on the internal taper shoulder of the Helios QD. Fitment issues were also occuring with other manufacturers silencers. We know it's not an issue with the CGS side of the equation since all of our parts are checked with thread gauges, and because they were rechecked when we took the parts back to see what the issue was. Soon after releasing Gen 2 KM, Dead Air then changed the design of the KeyMo mount again after there were issues reported here and elsewhere of KeyMo mounts not fitting various silencers due to male thread issues on the KeyMo mounts. The Gen 2 KM paired with the KeyMicro brake allowed you to use that specific combination of parts on the Helios QD without using the QD Adapter Ring that's included in the Helios QD kit. 275" of extra material in front of the threads (which I'll call Gen 1 KM). Dead Air released a new KeyMo design maybe four months ago, the version with no extra material in front of the threads (which I'll call Gen 2 KM), which replaced the old KeyMo design, the version with.
