I have a Beretta AR70 that I really like, and have evenmanaged to stock up quite a few mags for it. It came with the then-standard 1:12 twist bbl, which as you know won't handle the heavier bullets. I understand the AR70/90 is made with a faster twist, but they're not available in the U.S. Does anyone have any idea of how I could get a faster twist bbl for this rifle?
