it's pretty good, on/off all that.

by Jimmy, Verified Owner from PA, United States Written on December 24, 2025
It's solid, does what it's intended to do. Screws onto the thing and then you turn it around the things to lock it on. And it's great.

i put them on all of my intermediate to long range riffles

by Ringinthesteel, Verified Owner from TX, United States Written on November 19, 2025
I use them on anything I plan on shooting over 500 yards. They cut recoil in half, reduce muzzle flip, and help with follow up shots. Like any muzzle break they are obnoxiously loud but I always shoot suppressed so they act as a sacrificial baffle for me. I recommend them for SPR’s, large-frame AR’s, even bolt guns.

Quick and easy connections

by McQueen, Verified Owner from OK, United States Written on May 23, 2025
This item makes taking your supp on and off easy. No worrying about messing up threads and you're going to love the ratchet down part of connecting its marrying connection of your choice, mine was a flash hider.

Dead Air Armament Key-Mo

by Joe, Verified Owner from TX, United States Written on May 3, 2025
My recent purchase of the Dead Air Armament Key-Mo for my rifle set up was a great choice. At first I was undecided if I should use direct thread or use key-mo while using my suppressor. You pay a little more with muzzle break and key-mo set up but in the long run it’s easier to install your suppressor using .556 or 30 caliber rifle. I’ll definitely purchase again.

Review of Dead Air Armament Key-Mo

by James Williams, Verified Owner from OH, United States Written on March 25, 2025
This is a top of the line product. Once installed it works as advertised. With minimal effort you can switch you silencer from gun to gun. I would highly recommend this product to anyone looking for a QD for their silencer. Of course Optics Planet makes it even better with very quick shipment and one of the better prices out there.

Best System Ive Used

by UTVOL, Verified Owner from GA, United States Written on March 22, 2025
Plenty of options out there these days for hub mounting systems, but the Keymo is hands down the easiest and most efficient! Literally 3-4 clicks one directions to get it on. And literally three or four clicks the other direction to take it off. I just don’t see how it gets to be easier than that. Optics Planet two day shipping, then they actually have it in stock!
Pros:
  • easy to install
  • easy to install, exactly as advertised
Cons:
  • None for me

Best Suppressor Mount Available

by WildNorthman, Verified Owner from NC, United States Written on February 20, 2025
As per the installation directions, you need to buy a thread locker when you put this on a suppressor. DeadAir recommends a medium grade but I prefer and chose Rocksett which is rated for 2,000 degrees F. Don’t waste your money on inferior products like Loc-Tite or Vibra-Tite.

Once you’ve let the Rocksett cure for 24hours, the KeyMo works as intended and is perfection.
