Good budget optic if you have good (20/20) vision - AGM Global Vision Rattler V2 19-256 19mm Thermal Imaging Rifle Scope

This is a good 'budget' optic. You arent going to ID animals hundreds of yards away, they will just be hot blobs out in the field. The menu icons are tiny so you will need to read the manual to see which buttons do what. These are meant for AR15 platform. I would say good out to 100 yds, 150-200 would be pushing it. If you have the money, get the 384 or 640. I returned mine after one night to get the 384 instead. Im also looking at the Adder for a dedicated bolt gun.
