Dead Air Armament KeyMo Zero Features The Dead Air Armament KeyMo Zero is engineered as a quick detach mounting solution that reduces the mount s footprint in the blast chamber maximizing sound performance while minimizing overall weight. Its shorter profile means less intrusion into the suppressor s internal volume which helps the attached can perform closer to its rated sound reduction. The unique mass shifted equal length tine design also eliminates the ringing or ping sound some flash hiders produce under fire. Chambered for .30 caliber and threaded 1/2x28 it is a direct fit for rifles built around that common thread pattern. Constructed from 4140 heat treated chromium molybdenum steel and finished in black Nitride the KeyMo Zero is built to hold up to repeated mounting and dismounting without excessive wear. The mount includes a built in 3/4 inch wrench and socket feature for tool assisted installation and removal making it simple to service in the field or at the bench. Because it uses the KeyMo and KeyMicro interface suppressors attach and detach quickly without the carbon locking that can make removal difficult after extended firing. This makes the KeyMo Zero a practical durable choice for shooters running the Dead Air suppressor lineup.
