Well OPBN ask the question and I was the guinea pig

First step was to check what was preventing the two from mating
as you can see they are close but material needs to be removed for the AGD frame to fit




i cut the back off the stock because it was in the way of the rear screw on the frame




as I refit and cleared away more material from the stock the frame became easier to insert






I wanted to maintain the channel the posts on the frame ride in, but on the crossman frames the geometry is slightly different.
I took a used cutting wheel and cut the channel straight back. I used the painters tape as a guide






i cleaned up the front and checked alignment again, and marked a spot for the new hole from stock to frame






using a hand file and sandpaper i cleaned up the back




Drilled and tapped the hole 10/32






...and BOOM!!!
