I've read several posts that the CTR mags run more smoothly, others have been prone to hiccups, and don't want to purchase different mags if I have one that the rifle is designed to work with to begin with primarily.Chassis wise, not too many are setup to run the ctr mags. Manners does some of their stocks for the ctr mags(I just traded one). Why do you want to stick to the ctr mags?
There are some other options for stocks and chassis systems that allow the use of the CTR mags such as McRee and Bell & Carlson. I'd really like to utilize a chassis system but the options are limited in that regard if you want to use CTR mags.I would say if you want to go chassis, switch to AI mags now. If you dont mind a stock like manners or McMillan than you can stay ctr mags. I had a ctr with a manners t6a ctr inlet and ended up selling it and getting a mpa chassis. I know some guys like the ctr mags for longer oal on their reloads.
