Description

CAA MCK 3.0 Features For the first time the MCK 3.0 accommodates slides with mounted RMR/micro red dots enabling shooters to aim directly through their zeroed optic. The built-in cleaning solution incorporates robust bristles that remove carbon buildup from the front of the slide during cycling all while protecting the finish of the firearm. The ambidextrous stabilizer/stock now supports both left- and right-side folding for maximum flexibility. With two adjustable height positions the stabilizer allows for optimal aiming whether using slide-mounted optics or top-mounted sights on the Picatinny rail. The front adapter shields the MCK s interior from carbon buildup and is easily removed for cleaning while the 4.6-inch aluminum Picatinny rails on the top accommodate a variety of optics and sighting systems.
