Midwest Mk2 Acro Mount 1/3 Cowitness

The Midwest Mk2 Acro Mount 1/3 Cowitness is a precision optic mounting solution engineered for tactical shooters and law enforcement professionals who demand absolute reliability under operational stress. This mount bridges the gap between absolute and lower-1/3 cowitness heights, allowing your backup iron sights to remain visible and accessible while maintaining a low-profile sight picture through the Aimpoint Acro or similar compact reflex optics. Built for AR-platform rifles and specialized duty weapons, the 1/3 cowitness configuration has become the gold standard in modern tactical loadouts where mission-critical redundancy cannot be compromised.

Midwest Industries engineered the Mk2 series using precision-machined aluminum construction that meets military durability standards while maintaining a lightweight 1 lb package. The 1/3 cowitness height positions your optic bore axis at exactly one-third the distance between the upper receiver rail and iron sight height—this geometry prevents parallax-induced point-of-aim shifts that can prove fatal in close-quarters or dynamic shooting scenarios. Mounting directly to Picatinny rail systems, the Mk2 Acro Mount utilizes proven mechanical locking mechanisms that maintain zero through repeated deployment, recoil cycles, and environmental exposure typical of patrol rifles, precision carbines, and entry weapons.

Law enforcement tactical teams, military marksmen, and competitive operators benefit most from this cowitness configuration because it eliminates the "which sight am I using" cognitive burden during high-stress engagements. The 1/3 height works seamlessly with fast-acquisition reflex optics like the Aimpoint Acro or Steiner CQBL while preserving lower-receiver real estate for next-generation mounting systems. Installation requires standard gunsmithing tools and torque awareness; Picatinny compatibility ensures drop-in functionality across AR-15, AR-10, and modern tactical rifles without modification.
