I'll pass the info on to our newly appointed team leader for our newby unit. He'll probably difer to me on this since I'm a dept range officer and armorer but he's the grand-pooba.
However, I have several Mag-pul products installed on my own rifle and I'll never say it enough. buy as many of the enhanced followers as you can. Best thing to ever happen to the AR. I was able to salvage several magazines that had feeding problems. Some of the tolerances in mag width play havoc with the traditional followers and produce more frequent tilting (at least as far as my own experience goes). The new enhanced followers just don't care.
I also have the enhanced trigger guard. Looks awesome and cures the bite of the traditional guard. The MIAD grip I haven't gotten yet, but it's next on the list.
I'll push my team leader to get off his can and contact you.
