So much better than the generic factory scope from excalibur - Hawke Sport Optics Hawke 1.5-5x32mm Crossbow Scope

To say that I'm very pleased with this product would be an understatement. It's performance far exceeds the generic, one size fits all, scope that came with my Excalibur GRZ II. This scope gives repeatable accuracy shot after shot, which wasn't the case with the factory issued glass. The Hawke is very clear from edge to edge, once I adjusted the ocular lens for my particular eyesight. The elevation and windage adjustments are precise, with nice audible clicks. The reticle is busy, but isn't so cluttered as to distract you while shooting. I can not attest to the attributes of the green/ red adjustable illuminated reticles as I have not used them while hunting and they weren't needed while dialing in my scope. The instruction manual was easily understandable and I was able to sight the scope in quickly. The flip-up lens covers were a nice bonus. The only con that I can find is that there isn't a lot of area for scope rings between the objective lens/turret/ ocular lens.
