Hell, I'll keep the barrel I've got. It's an Olympic 16" full-heavy, fluted, non-chromed, pre-ban. Probably got about 50 rounds through it. I was going to get the same thing in a chrome-lined Bushy and sell the Olympic, but I think I'll just stick with it. It was kind of a hare-brained idea anyway. I got the feeling several years ago when I shot it last that the barrel wasn't accurate. I think I need to go back to the range, take my time and just see how it shoots. At the time, I had another Bushmaster, a 20", that was a tack driver, and going from that to the 16" carbine with the short sight radius, I was all over the paper. I need to sight it in for the modified Battlesight zero anyway, and the sight is already re-set.
