I’ve got an ARC CDG in a Manners LRH mini chassis, Hawkins CIP length M5 DBM, and my MDT 300 PRC mag won’t latch.

I know, obviously I need to adjust something, but what is easiest? Chassis, bottom metal, mag?
 
Not sure if the Long action is the same as the Short, but you may need to shorten your mag latch to get them to go.

If you hold the mag in, does everything feed well?

If so, Use some dry erase marker on the mag's catch then put it in. Take it out and see how much you need to take off the latch.
