You'd likely love the Kidon then!I've been running the MCK with my Canik...it does the job, just wish I could source the buffet tube adaptor or a pic adaptor so I could get a LONGER length of pull for my 6'6 gorilla frame
The other thing I should maybe mention is that to balance out the weight of the Shadow 2 I installed a standard buffer tube (instead of the solid plastic one) with an H3 weight and spring in it. That solved a bit of a front heavy situation I had before. I doubt this would be an issue with a "plastic" gun but the Shadow 2 is such a heavier frame. The B5 stock makes for a nice comfy check weld as opposed to the factory stock (which is just okay).
Screwing in a metal buffer tube into the plastic threads of the Kidon chassis was to say the least unnerving. A cross threading there would have been very expensive!
Also with the CZ attachment I can slide in a shadow 2, Shadow 1 or SP01 Tactical (not a Tact Sport) without changing anything. Just need the charge handle set for the longer gun which is the Shadow 2.
Photos show factory stock vs B5 stock. Note that photos were taken with the same factory solid plastic buffer tube installed. I also ditched the factory sights for my trusty Eotech.
