The Dead Air KeyMicro Legacy adapter (brand part no. DA452) puts KeyMicro quick-detach muzzle devices on suppressors with a legacy pistol socket. Dead Air Silencers lists it for SilencerCo, including the Alpha, Rugged and similar suppressors, rather than for its own P-Series cans. It is the legacy counterpart to the P-Series KeyMicro adapter and uses the same mounting technology as the KeyMo system, sized down for pistols. It is machined from 17-4 stainless steel with a black nitride finish.

Key Specifications

• The socket is the legacy pistol socket, found on suppressors from SilencerCo, including the Alpha, and Rugged.
• It is compatible with KeyMicro muzzle devices, the pistol-sized version of the KeyMo mounting system.
• Material is 17-4 stainless steel, a durable alloy for a part that is installed repeatedly.
• The finish is black nitride, a hard coating that resists wear.
• Overall length is 1.660 inches, as Dead Air lists for the Legacy version.
• Weight is 4.11 ounces, which Dead Air lists for this version.
• It is covered by Dead Air patent 11441867, the quick-attach mounting system.
• Dead Air notes that smaller blast chambers are typical on pistol suppressors, so fitment with full-size KeyMo devices depends on the suppressor.
• It was designed first to pair with KeyMicro muzzle devices, though it will work with some full-size KeyMo devices.

Frequently Asked Questions

Is this adapter for older KeyMicro suppressors? No. Dead Air lists it for the legacy pistol socket used by suppressors like the SilencerCo Alpha and Rugged. Its own Wolfman, Mojave and Ghost-M use the P-Series adapter.

Does it work with KeyMo muzzle devices? Dead Air says the KeyMicro adapters are compatible with KeyMo and KeyMicro muzzle devices, but fitment depends on the suppressor, because pistol suppressors usually have smaller blast chambers.

How does it differ from the P-Series version? The Legacy adapter is 1.660 inches long and 4.11 ounces, while the P-Series adapter is 1.650 inches and 3.70 ounces, and each fits a different pistol socket.
