I've always been a FAL guy but maybe want to add an AR-10. I have the cash for a scar 17 but do I need a $2800 gun to put the Zeus on? I ask here because I'm sure you guys are familiar the drill I'm doing.......Zeus on a rifle with a Cqbl, shooting tripod, shooting to 200. Cruising around in a ranger zapping hogs. Who's got one and how are they performing?
