I would like to get a Magpul MOE+ grip and use one of the bolt/firing pin grip cores to hold spares in the grip. Anyone using the two together? I read on Magpul's site that they do not recommend the bolt/fp core to be used with the MOE + grip because the grip is slightly different than the MIAD and MOE grip due to the overmolding. I was thinking maybe I could get it to work by clearencing the inside of the grip or something. Thanks in advance.
