M16/M4 selector plate is what you're after. Cant remember the size of bushings used in the AGM MP44 off the top of my head - it's either 7mm or 8mm. Best to check before you order that the selector plate will clear them.
Fackin' hell. Just looked at that website. Nigh on 300 Euro for an AGM MP44. Bloody ripoff merchants.

they are 8mm bushings and i found the selector plate slightly thicker thana average selector plate.
Best to give Frank or John @ Firesupport an email - they'll be able to tell you the exact one required!
