[QUOTE="bamban, post: 2846189, member: 17722"] We never really made any extra effort to do. I know a couple of custom finished barrel gunsmiths will charge you extra if you want the port timed. Anecdotal, I have 2 barrels in the shop I spun up for a friend. By accident the ports landed in the groove. Both were melonited and they lasted over 10,500 precision lives and probably would have lasted longer had I convinced coerced my buddy in swapping out. In the one with 10741, shooter posted 198-8 at 6 before I pulled the barrel. Another barrel returned from the JR program, had less 3000 rounds when it was pulled out due to severe drop in Xs at 600, and shots not on call. I have not inspected this barrel. During the M14 days, this subject was debated extensively. Hole in groove provided better precision, only to be debunked, then argued again. I do not have any preference for my own weapons. [/QUOTE]
