How difficult is putting a retractable stock in an m4?
 

Hey all i have a G&G gr-16 r4 with full stock and i want to change it to a retractable stock. Now i was wondering is there a site where it can show me how i can convert it and how i can re-route the internal wires for a ready mag battery?

can someone move this to the other forum i just relized it, my bad
