Police Trade-in ITT 2.5-10X56mm Scope. 30mm tube. These scopes came with a clip on night vision unit (not included). This Scope came from a law enforcement agency. It is used with a few small scratches and wear marks, it works great. Glass is very clear with no scratches or cracks. The 56mm lens lets in a ton of light and gives a wide field of view. We personally tested this scope on a PTR91 out to 700m and it worked great! Reticle is in MOA, .25 MOA per click. Sold as is, no returns.
