Well if they're selling a $930 scope for $300, that's a pretty good price if the scope is genuinely worth $900+. I don't really know much about Weaver optics, so I'm not qualified to comment otherwise.
As far as a 56mm objective lens goes, there is a tradeoff to be had, much like the tradeoff when one goes from a 44mm objective lens to a 50mm objective lens. On the plus side, you theoretically gain some light gathering ability, although a higher quality 44mm lens will gather more light than a lower quality 56mm lens. If Weaver scopes are known for good glass (I honestly have no idea), then you should have a really bright field of view. (There are other factors too like clarity of the glass, and freedom from defects in the glass.)
The downside is the effect of the objective lens diameter upon the height of the scope over the bore. As a general rule, you'd prefer the scope body to be as low and close to the bore as possible without negatively affecting your ability to line your eye up with it. With rifles that have some drop to the comb, a lower scope is easier to deal with because the shooter's sighting eye is lower relative to the bore. With an AR and it's straight stock with no drop, the scope height can be higher. The scope height has an impact on bullet trajectory.
But most of this stuff is really theoretical, and unless you're a sniper making routine 1,000 shots, this won't affect you much other than as an issue of comfort behind the scope.
