KEYMO MUZZLE BRAKE Reviews & Ratings

The KeyMo Muzzle Brake is your gateway to silence. When you’re ready for peace and quiet use the KeyMo brake to quickly attach your Sandman Series or KeyMo equipped suppressor to your rifle. If you’re not quite ready to turn up the silence, you can still employ the finest brake on the market and experience a flatter shooting rifle with minimal concussion compared to traditional muzzle brakes.

Dead Air’s sealed taper design is forward of the Keymo locking channels, allowing the suppressor to be easily removed without carbon-locking onto the mount.

NOTE: The DA101 and DA102 come with a pre-drilled hole for pin & weld at the 6 O’clock position. The DA103, DA104, and DA106 do not have a pin/weld hole and do not have the three port holes on the top wrench flat.

Dead Air Brake DA102

I'm running two of these 7.62 Dead Air keymount brakes. One is on a SCAR17 (with KBAC shoulder ring) and the other on a CMMG Mk3. Both installed fairly easily and were darn near dead on with my Saker cans when checked with a Geissele alignment rod. These do come with timing shims, although the O.D is considerably wider than the barrel diameter. With the SCAR17's unique barrel profile, I opted to use a set of AAC shims. Also, an FYI regarding the SCAR, this is one if the muzzle devices which will not fit thru the KDG MREX rail. With a bit of creativity and patience, however, both parts can be compatible. Regarding performance, it's your typical 3 chamber brake. Recoil impulse is straight to the rear with almost no muzzle rise. I've shot it indoors but I can't attest to its claim of less concussion because unfortunately I was the only one on the line. Overall, I believe this product is an excellent value at a competitive price range.
