I'm looking to slowly build a rifle part by part, on a very tight budget. From everything I've read and watch it looks pretty easy. My main concern is the barrel install, and head spacing. If the barrel and the receiver are already indexed how can you correct head space or would that be a faulty barrel/receiver? Or maybe I'll forgo the headache and find a gunsmith to install it, dose anyone know a rough price of a gunsmith? And I'm around the Columbus area. Thanks.
