I have a few of HI's barrels and have been happy with them. I also called to get some more detailed information on port sizes on some of the 5" barrels a while back and the I got transferred to someone who walked into the back to drop gauges in the ports for me. FYI the 5" 7.62x39 barrel cycles subs perfectly with a can.

anyone test either of the 6.5 grendel barrels?
