I have a 243 win and a 6.5 Creed that are both being converted to accept AICS style mags. I’m not super familiar with the magazine options out there. Can I buy some .308 based AI fit mags and have the mags work with both of my cartridges?
AICS mags are easier to tune than PMAGS. I have 2 PMAGS that will run in my rifle but it took a lot of file work to get them there. AICS you can just polish and bend the feed lips. I have the MPA tool for the feed lips and like it. Well worth what I paid for it.
