Solid Rifle Scope by Tom, Verified Owner, May 6, 2025
So far so good. Built like a rock. This scope has very clear glass and a great reticle. The turret clicks are well defined. On the base of both turrets are up/down or left/right arrows. You can move your eye up from the scope a little and verify...
