I have a Savage model 10 in a McRee chassis. The AICS mag functions fine.
The Ruger, at first, couldn't be inserted, it's too wide. There are reinforcing ribs on the body of the magazine that have to be removed at the rear of the mag. Once these are removed, you can insert the magazine.
There are extensions to the feed lips, I suppose to strengthen them, at the front. These are absent on the AICS. When inserted and removed, you can see marks on these feed lip extensions. I removed a little at a time to the point I'm getting almost no marks. The magazine appears to seat as far as the AICS.
I thought I was ready to try feeding cartridges. No go. The bolt picks up the top of the case rim, the cartridge begins to go forward slightly, then the bolt over rides the case. It's almost as if the spring is too weak.
Anyway, that's where I'm at. </div></div>
It is not that the spring is too weak, the magazine is not far enough up into the action, the DBM could be inletted deeper bringing the magazine into the action. The ride over is exactly what happened with the AI 223 mags until I got the magazine far enough into the action, then they feed fine and 308 (metal mags)feed very smooth with the same set up </div></div>
ive got the atlas worx bottom metal that takes aics mags, its similar to the badger in terms of compatibility. if i have my gunsmith inlet the rifle a bit higher, how much of a risk is it to mess the whole thing up and make it where other mags won't feed? also any idea if i have him do this if it would be reversible? id love to get these mags to work. i bought a 5 rounder and im going to try to figure something out.
any idea why the polymer mags seem to always need a higher inlet? seems strange to me </div></div>
see my posts,and others on the atlas works thread for inletting details including exact pillar lengths, IMO the steel 308 mags fed smoother when the DBM was inletted deeper
it is reversible?, yes just use epoxy/bedding to bring the DBM to a shallower position
no idea about polymer vs steel, I thought it was the smaller diameter of the 223 vs 308
