Looking at putting together a rifle on a Curtis Axiom. It'll be in 6.5CM. I know the ARC mags are not popular because of reliability issues but I have 2 with AREA 419 bases that run flawlessly in my RPR. I like the low profile/high capacity I get with these. I'm looking for input from anyone running an Axiom with the ARC mags in an MPA or maybe an XLR chassis? I'll be using this rifle in PRS style matches. Thanks!
