As good as the TL3 action is, and it is very good, AW Magazines were designed to run with 3 lug actions not two like the TL3. They can run in a two lugger, but not as smoothly and bobble free. AICS mags on the other hand present the cartridge rim at the ideal angle for a two lug action. IMHO and YMMV
My TL-3 are AW cut but I run ARC mags in them. Filed the wings off the followers and polished the follower with steel wool afterwards. Runs like butter.
Why did you polish the follower and where did you do it? I have a surgeon action cut for aw mags and the ARC mags sort of work. Still have the problem of the round below another one getting drug forward and causing jams.
