Does anyone have any diagrams on how to switch out buttstocks?
I have an A2 buttstock on my 20", but I'm going to be getting a collapsable one pretty soon and I don't have the first idea on how to switch them out.
The information button top right of web page has a listing for the manuals. Take a look at the m16/M4 one. Some info in early part of the 2 section and in the 3 section of the manual.
