Hi guys, this one came out nice, I did ours here with a Boyds Thumbhole stock.

The MDT mags have a sharp feed lip at the rear and we just bevel it off so the bolt will push the mag down when loading a new mag. The AI mags have a little different design and isn't an issue, the DBM needs to be compatible with both, so the MDT moves a little more than the AI does. Heres pic of the trim mod that makes it all good
