RC20, thanks for your input regarding the standard cambering. I assume you have been happy with yours and don't have any issues loading long to get out to the lands while still staying under magazine length?

I did the bead blasting for the looks and will make it easier if I decide to cerakote later.

I did have the muzzle end threaded since I shoot almost exclusively with a suppressor (Specwar 762). So long as I don't lose muzzle velocity with the new barrel I will be fine at 1,000 yards and figure the shorter barrel will increase rigidity, not to mention making it fit in the safe nicer.
