Airsoftparts.ca also has the magwell spacer.
Ill ad to the mag fitment issue. One metal mag i have (unknown brand) and the gandp waffle mags i had also didnt fit correctly the front block needed a mm or so shaved off of each side or they are just too tight. Took 5 minuts sith a file to do 4 mags now they fit perfect.
Save yorself hassels and just buy lct mags they are nice!
Also if you plan on changing hop up rubbers and inner barrels do it befor puttin the magwell spacer in its a pain to remove without removing the gearbox and makes it imposible to remove the inner and hop up assembly
