Be careful. Your thinking that crossbows are easy on scopes is incorrect. I had the crosshairs on a 4X break. My Horton vibrates violently when shot and recoils much like an high-power airgun...and it is common knowledge that airguns are tough on scopes because of the forward recoil. I literally glued and loc-tighted everything. Scope mounts were constantly slipping foward. I even retapped several holes for larger screws to hold better.

I was very accuarte with my scope out to 40-50 yrds (practice) but most of my deer are shot at 10-15 yds. At this range I found the small field of view to be a great disadvantage. I use a single pin set at 20yds and feel this is the best set up for my hunting style. A scope does work but I would keep an eye on your zero to make sure the mounts aren't slipping or the scope isn't "going south".
