On those mags, look at the front edge over which the cartridge travels during the strip and feed. I lowered mine by about 0.120" with a dremel b/c for the 6Arc geometry they tend to either scrape like yours, or get blocked from feeding, the edge of the case mouth hangs up on that front edge (there's some thread on this issue on here). You can then round that edge with a small file or some sandpaper. I think I'm using lowered front edges on all my 6Arc mags, no matter which rifle I'm shooting. There's a spot weld even farther down on the mag front to hold everything so shouldn't be an issue just getting that edge out of the way.
