I'm looking at getting either an MCR or a wk180c. I know that overall the MCR is better quality, but I like that the wk180c has more parts available online. Is it possible to use ar-15 barrels on either of these? if so what about hand guards? Ideally I would like to have an 18.6" for some cqb courses my friends and I have built, and a 22" (or slightly longer) for longer plinking and some pest control. Is this possible to do on either of these? I understand the MCR has a 7.62x39 model, could this be used like an ar-15 to change calibres with the upper? thanks for any info
