DEAD AIR ARMAMENT KEYMO FH FAL 9/16X24 LH

Description

The Dead Air Silencers KeyMo is a muzzle brake, threaded 9/16"x24 LH.

A muzzle brake redirects escaping gas sideways and rearwards to push back against recoil and muzzle rise. The gas it redirects has to go somewhere, so a brake makes the rifle louder and sharper for anyone standing beside it.

This part is threaded 9/16"x24 LH, which is not interchangeable with other pitches. Thread pitch has to match exactly – a near miss either will not start or will cross-thread, and a damaged barrel thread is a gunsmithing job.

A muzzle device fitted to bring a short barrel up to the legal 16 inches only counts if it is permanently attached – pinned and welded, or silver-soldered. Simply screwing one on does not change the barrel's measured length.

This is a part, not a regulated item. Mounts, pistons, caps and muzzle devices are not NFA-controlled and ship directly to your address – the suppressor itself is the registered item.
