I'm running BDL on that one, but I cut down the mag box spacer and re-welded it before coating the barreled action. After the mag box mod, 2.45" isn't a problem now at all. I run 5 down in the mag with the 75AM, and it feeds beautifully.

But after using the Atlas and AICS mags a bit on this .243AI, I'm sure the .223 will get the same treatment at some point...
