Product description
The CAA MCK Gen 2 conversion kit for Polymer80 v1 and v2 frames is CAA's answer to builders who finished their own 80% pistol. CAA's compatibility list names the PFC9, PFS9, PF940v2, PF940C and PF45. If your build uses one of those frames, this is the MCK version to order.
Builds vary, and CAA planned for that. The kit comes with two charging handles, one for Glock slides and one for Polymer80 slides, so you can match the handle to the slide on your frame. Installation needs no disassembly. Put the pistol in, lock it, and you're set.
This version comes standard with a polymer top Picatinny rail for sights and optics, plus side rails for accessories such as thumb rests. The rear door opens an extra 15 degrees for easier loading. It accommodates suppressor-height sights and suppressor diameters up to 1.38 inches. The front spare magazine holder uses a mag catch and release button, and the kit works with the MCK Gen 2 Brass Catcher. A flashlight, flip-up sights and thumb rests are not included.
Pick OD Green, Black, FDE Tan or Tungsten Grey. CAA produces the MCK in the USA. The 1-year CAA warranty requires registering with CAA no more than 30 days after purchase. Rules on conversion kits vary, so make sure your state allows one before you buy.
