The 416-SD was designed specifically to meet military requirements for CQC weapons and operations. AAC's patent pending Ratchet-Mount fast-attach mounting system provides reliable precision accuracy with minimal and repeatable zero-shift. Users have the ability to install or remove the silencer from the Blackout™ flash eliminator in seconds in the harshest military environment. The ultra-compact size and light weight have minimal affect on maneuverability, which proves crucial in CQC environments.
The 416-SD's extreme durability is maximized by CNC automated fusion welding of every high-temperature aerospace alloy component used in its construction - making 100% suppressed fire possible. The back-pressure lowering design of the silencer aids in shooter comfort, reduces weapon fouling, and minimizes cyclic rate increase. As a final step, EDM technology is utilized to ensure precise bore alignment resulting in enhanced accuracy. The reduction of muzzle report reduces the need for ear protection, preserves field communications, and masks the location of the shooter. Eliminating muzzle flash in combat saves lives.
