A2 receiver to A3 receiver
I have a Bushmaster AR-15 with a A2 style receiver, I would like to change it to the A3 flat top style to be able to mount optics lower to the barrel bore. Would I be better off to purchase the A3 style receiver and have it installed, or purchase all of the needed equipment and learn to do my own work? thanks for your thoughts.
