Maybe you can clue me in on how one can get some ramps cut in the bolt lug abutments... converting a right hand AR-30 into a lefty?
I was told a gentlman on the east coast makes barrels with an EDM for the Contenders, a slow process, 8 hrs I think was stated. He does others too if you want a one time job and don't need a reamer later if you plan on setting the bbl back and doing it again. He charges about $150 I was told.
My smith, Dave, he was making a brake with Ti last month for a big boomer he was building a guy.
