The Dead Air KeyMo Flash Hider SCAR 16 1/2-28 is a .22 caliber muzzle device from Dead Air Silencers (brand part no. DA306), threaded 1/2-28. Dead Air lists this pitch for the SCAR 16. It is machined from 4140 heat-treated alloy steel with a Black Nitride finish, and its mass-shifted, equal-length tines cool burning gas without the ringing ping of a traditional three-prong design. A SCAR 16 shooter can run it bare for flash reduction and keep the KeyMo suppressor option open.

Key Specifications

• The muzzle thread is 1/2-28, the pitch that decides which barrels this version fits.
• The through bore is sized for .22 caliber barrels, which matches the thread pitch it is paired with.
• Material is 4140 heat-treated alloy steel, chosen to hold up to heat and repeated suppressor mounting.
• The finish is Black Nitride, a hard surface treatment that resists corrosion and wear.
• Overall length is 2.70 inches, long enough to carry the tine design without adding much to the muzzle.
• Weight runs 4.00 to 4.08 ounces depending on thread pitch, a modest load on the end of a barrel.
• The tines are mass-shifted and equal in length, an arrangement meant to disrupt and cool burning gas before it ignites outside the muzzle.
• The design eliminates the audible ping that traditional three-prong flash hiders make, so there is no ringing when it fires.
• It belongs to the KeyMo mounting system, so it works on a bare rifle or as the interface for a KeyMo-equipped suppressor.

Frequently Asked Questions

Can I run it without a suppressor? Yes. Dead Air designed it to give strong flash suppression whether the rifle is run suppressed or unsuppressed, and it is part of the KeyMo mounting system if you add a KeyMo-equipped suppressor later.

What thread does this flash hider use? It is threaded 1/2-28 with a .22 caliber bore. Dead Air sells the KeyMo Flash Hider in several thread pitches, so match this one to your muzzle thread before ordering.

Will it ping like other flash hiders? No. Dead Air built it with mass-shifted, equal-length tines specifically to remove the ringing ping that traditional three-prong designs produce.
