Take your aics 223 mag apart. Take some masking tape and place it on the outside of the feedlips marking them at 0.400" wide, this serves as a simple visual reference of how much you need to take off/remove. Take a mill if you have one or a dremel, like I did
and tkae your time and open it up. When this is done drop a 6br round in from the bottom, you will see that the mag narrows at the top before the round gets to the feed lips. This area needs to be sanded/ground open enouogh to allow the cartridge to get to the feed lips, sand this out at the same angle the feelips are at, go slow and keep checking with your test round.
This should only take you 15-20 minutes, it's a quick fix and if I was going to do any more I would modify these mags before a 5rd 308 mag just because it is easier and you end up with more capacity.
This last section has to do with how the mag sits in your bottom metal, with my 6br this was the key to what made it feed without flaw.
The last thing you need to do is insert the mag into your rifle, after it has latched grab the mag and see how much up and down slop there is, on my badgger m5 it fits tight as it should, however on my surgeon dbm there is a lot of up and down slop, enough that I would get stove pipe type jams, I tried this on both my surgeon dbm's with equal amounts of slop, imo this needs to be fixed by remoming the "tbar" release on the surgeon and welding more material to the top of the release then grind it down to where it needs to be. The other way to fix this is to take a bit of devcon and add length to the release catch on the magazine, once it's set up file it square. Make it so the mag seats easily but without much up and down slop. By doing these things my 6br fed great, better than it ever has.
Good luck guys,
