The Dead Air DA428 Key‑Mo Adaptor serves as a bridging interface between KeyMo-compatible suppressors and non-KeyMo muzzle systems. Constructed from hardened steel with low-friction nitride, it ensures durable performance and reliable torque retention.
Precision-machined to OEM tolerances and coated in matte black Cerakote, the DA428 adaptor ships with a detent pin and anti-rotation tabs for secure alignment and a solid, repeatable lockup. It enables shooters to mount suppressors like the Primal, Nomad, and Sandman-L directly to 5/8×24 threads, 3-lug setups, or booster-equipped rifles.
Weighing just around 1.5 ounces, it adds minimal weight while significantly improving modularity. The DA428’s rapid attach/detach design maintains point-of-impact consistency, making it ideal for field use and quick transitions between suppressed and unsuppressed configurations.
