MCK Gen.2 - Micro Conversion Kit made by CAA of lightweight yet robust construction. MCK Gen.2 has an improved design to make it easier to insert and easier to use even with a folded stock, increased opening for shell ejection and new cocking handle.
The conversion is made for the Gen. 5, 4 in 3 Glock 17/19 which fit perfectly and sit firmly inside. Fixed to the lower rail and secured with a guard at the rear of the handle, and the cocking system grabs it along the entire length of the slide, allowing efficient and safe cocking. On the sides there are plastic Picatinny rails, and on the top is an aluminum rail for optics and dots.
