Dead Air Detent Ring for KeyMo & KeyMicro Adapters – DA012 Black

Description

The detent ring is one of those parts nobody thinks about until it starts feeling tired. It is the little plate that gives your KeyMo mount that positive, ratcheting lockup when you spin the suppressor onto a muzzle device, and after enough mounting cycles and carbon buildup, keeping a fresh one on hand just makes sense. This is the genuine Dead Air replacement, part number DA012, so you are getting the exact same component the factory installs, not an aftermarket guess.

One Detent Ring, Most of the Dead Air Lineup

Here is the handy part: this single plate covers a lot of ground. It fits all DA428 KeyMo-HUB adapters and DA451 KeyMicro adapters, and it is the same detent plate that ships standard on the entire Sandman series and the Sierra-5 KM. If you run any KeyMo-equipped silencer, this is the part your mount relies on for that secure, repeatable attachment. Folks who own more than one Dead Air can often grab a couple of these and call it good for the whole safe.

Built Like the Rest of Your Dead Air Gear

All-metal construction with a black nitride finish means it holds up to heat, carbon, and solvent the same way the factory part does, because it is the factory part. At a hair over an ounce shipped and roughly 1.3 inches across, it takes up basically zero space in a parts bin or range bag pocket.

Why Keep a Spare Detent Ring Around

Dead Air designed this listing for people who like maintaining their own inventory of moving parts, and that mindset pays off. Suppressor mounts live a hard life under heat and fouling, and small wear items are always the first to go. Swapping in a fresh detent ring restores that crisp factory lockup and keeps your mount indexing the way it should. Cheap insurance for gear you have already invested plenty into.
