What mount is that Tim? Looks like a side mount only as per Bassett style, holds zero AOK? I'm interested in trying a Bassett as it would let me put optics on and off rapidly while maintaining zero (or very near) without leaving the mount on all the time, as I generally prefer irons but here and there a scope is fun.
Believe it or not, that is the much hated aluminum B-Square that I bought back in `96 for it. It heal zero fine for the 600 or so rounds I've put through it. I've upgraded the mount to an ARMS18 because it MUST be better. I am still up in the air about rings that will work with the fat ass Falcon Menace scope I want to put on it.
