Dead Air KeyMicro Legacy Adapter

Dead Air DA452 KeyMicro Legacy Suppressor Adapter - HUB 1.375x24

Get access to Dead Air's proven KeyMicro quick-detach mounting system on suppressors you already own — the Dead Air KeyMicro Legacy Adapter lets you convert non-Dead Air pistol suppressors from brands like Rugged and SilencerCo over to Dead Air's hassle-free mounting interface.

Simply replace your existing fixed mount or booster housing with this adapter to convert common 1.375x24 threaded suppressors over to the KeyMicro quick-detach system — the same proven mounting technology found in Dead Air's Sandman and KeyMo systems, sized down specifically with weight savings for pistol silencers. Once mounted, your host firearm needs a compatible KeyMicro muzzle device (sold separately) to complete the quick-detach interface.

Built from 17-4 stainless steel with a corrosion-resistant Black Nitride finish, this adapter is genuinely durable for regular suppressor swaps between hosts. At just 4.11 oz and 1.660" in length, it adds minimal bulk or weight to your existing suppressor setup. Keep in mind that exact fitment depends on your specific suppressor, since smaller blast chambers are typical of suppressors optimized for pistol cartridges — this adapter is designed first for Dead Air's own KeyMicro muzzle devices, though it will also work with some full-size KeyMo muzzle devices depending on the suppressor.

Whether you're looking to bring a non-Dead Air suppressor into a KeyMicro quick-detach setup, want the convenience of fast suppressor swaps across multiple hosts, or need genuine stainless steel durability for an adapter that sees regular use, the KeyMicro Legacy Adapter gives you real mounting flexibility without buying an entirely new suppressor.
