I have an AR-15 barrel I want to get turned down forward of the gas block to eliminate the ridiculous "gov't profile." Who can do this for me here in Oklahoma? I know about Adco and AR15barrels.com, but I would rather not ship it out of state if I can get it done somewhere around here for a reasonable price. I can re-parkerize it myself if need be, but it would be nice if I could have this done while it is in the shop as well.
