This is a very high-quality scope. I got a real deal on these that I’m passing along the savings. 6 x 24 with a 50 mm objective lens and a 30 mm tube. Locking turret, so your zero won’t change, but you still have full adjust ability for windage and elevation. The reticle is a circle with a dot inside that can be illuminated red or green with mil dot markings. I love mine I’ll probably regret selling these. For more complete specifications, go to the Shepherd web site and look up the rouge series scopes. I have Leupold, Vortex and Nikon scope on some of my other rifles and I would rate this scope as good or better than those scopes. I have this same scope on 1 of my rifles and love it. The glass is clear all the way to the edge with excellent light gathering properties. Locking turrets. Just a great scope overall.
