Impressive optic even when mounted to a caliber it wasn’t designed for. Shot solid silhouette shots at 500 meters with a RT-S3 4.5×18 from a 7.62 bolt action platform. Since it did so well at 500, we pushed it out to 1000. Guess what it did? Hit, Hit, Hit, Hit and Hit. 5 for 5. It’s had over 200 rounds put through it, and reticle is rock solid, but the damn scope is built like a M1A1 battle tank. You’re not going to break this optic…not in this lifetime. Hell of a job RITON!
