Re: AW Mags in an M2008/Manner combination
Ratbert,
Assuming the AICS mag fits and functions as is and the AW mag will not lock into the magwell, you will need to remove the mag catch and "shave off" a few thousands off the top and test fit until you have removed enough. I assume the M5 bottom metal will have the same tolerances and procedure. I did mine on an AICS stock that GAP machined for the M2008. If the M2008 footprint was milled a few thousandths lower in the rail, it might not have required any fitting of the mag catch for the AW mag.
I hope this helps,
Darin
