Dead Air Sierra 5
The Dead Air Sierra 5 is Dead Air's dedicated 5.56mm suppressor — purpose-built from the ground up for the 5.56 platform with no barrel restrictions and full-auto capability. Welded Cobalt-6 (Stellite) baffles in a stainless steel tube deliver exceptional sound performance, flash suppression, and durability under heavy firing schedules. The Sierra 5 features a 1.375×24 HUB mount socket for maximum mounting flexibility (KeyMo, Xeno, direct thread, and third-party systems), ships with a flash hider front cap that is fully interchangeable with all Dead Air R-Series / Sandman front caps, and includes knurling on the exterior tube for a positive grip with heat wraps. Available with Xeno ($859) or KeyMo ($929) configurations. Dead Air Lifetime Warranty.
