Also posted to DGJ forums. The only "work" I did on this was to pull out my wallet. I don't know who did the work nor when but someone put a lot of effort into this. The stock was originally a military one. You can see the cheekpiece was added as it does not have the same 'tiger striping' as the butt. The pistol grip was added and, in hand, one can barely make out a seam in the checkering. The finger grooves were also filled in and checkered but I haven't been able to find a seam in either one.

Probably the most unusual feature is the magazine. The clip release lever in the trigger guard was changed to a 'bottom metal release' and the loaded en bloc clips are loaded in from the bottom. It's a little clumsy but the work is first rate.

Sorry---trying to figure out how to resize. Will edit if and when I do.
