Owner conversion consists of replacement of the magazine shell and follower with new components.
Conversion is easy and reliable.
Disassemble your M-14 magazine. Save the shell and follower as proof of conversion. At the top of the follower spring, the end of the spring sticks out to the side. This material normally hooks into the M-14 follower. If used with the AR-10 follower, this section would rub on the inside of the magazine box.
