I currently have a DPMS 5.56/.223 complete rifle and I was wondering what to I have to do to the lower so I can use it with a 9mm upper? I'd love to take the AP4 to indoor ranges and, 9mm is cheap to shoot.
I'd like to switch back and forth between 5.56mm and 9mm between shoots. Does anyone else do this here? I do not have much skill with gun smithing so I hope it is not a complicated process.
