DEAD AIR | KeyMo Zero | 1/2-28 KeyMount

The Dead Air KeyMo Zero is a compact, quick-detach muzzle mount designed to provide a lightweight, repeatable interface for KeyMo- and KeyMicro-equipped silencers. Its reduced profile minimizes intrusion into the suppressor’s blast chamber while the mount’s design resists carbon locking for straightforward removal. Constructed for durability, the KeyMo Zero combines a minimalist footprint with tool features intended to ease installation and removal.

Typical uses include range training where fast, repeatable suppressor changes are valuable, and precision or competition shooting where minimizing added length and weight at the muzzle preserves balance and handling. The KeyMo Zero is compatible with Dead Air KeyMo and KeyMicro adapter-equipped silencers and incorporates tool features for straightforward maintenance.
