Ever rebarrelled an AR? Here's some of what goes into the process of rebarrelling an M14/M1A Match gun. Pics taken during a recent trip up to get some AR-10 and M14 barrel work done. Some of the pics related to the AR-10s are posted on another thread here. The top photo is the soon-to-be barrelled M1A receiver and the bolt that needs to be fitted and headspaced. The bottom pic is the beginning of the long, slow and torturous step of hand reaming the final few thousandths of the chamber. Ream, clean, reassemble bolt, receiver and headspace gage, recheck, and repeat. Over, and over, and over again.
