AI feeding problem

I think I'm going to have to contact them. It also leaves rings on the brass and chamber looks rough.

I have the Choate Tactical Stock with CDI Bottom Metal on a 12FV .223. It also feeds intermittently as described above. Most rounds will feed just fine, although some may require a double-clutch of the bolt. It is almost like the bolt doesn't catch the round right. Then the last several will pop up and the bolt pushes them above the chamber at a steep angle. I'd thought maybe it was the MDT magazine, but sounds like it may be one of those "is what it is" things. Still vastly better than feeding a 4-round blind magazine in the factory stock.
