We've got a few of the 1" tubed 50mm VX-Ls in. Our rep was in the other day w/a 4.5-14x56mm. If you look in their catalog, this scope has turrets on it. However, their production model will not. The 6.5-20x56mm will, but not the 4.5-14x56mm /ubbthreads/images/graemlins/frown.gif /ubbthreads/images/graemlins/frown.gif /ubbthreads/images/graemlins/frown.gif. Great idea, I bet med rings will work on the 56mm!!! Kinda heavy though, the 4.5-14 weighed in @ 24 oz.
