Flir pro pts233 - FLIR Systems Thermosight Pro PTS233 1.5-6x19mm Thermal Imaging Weapon Sight

Amazing quality both in thermal images and the sights overall construction. Loaded with features and options at very low price compared to competitors. Also, it appears all new production Pros have been upgraded to the faster 60 Hz video re-fresh rate. This is an excellent buy.

Negatives if I had to find any! The buttons on the unit need to be pushed pretty aggressively to function. Not easy with cold hands or gloves, but a minor inconvenience.
The mount, which is robust and awesome, has a rear release lever that is not AR charging handle friendly when the sight is placed to the rear most rail position. I was able to remove and reverse the lever to accommodate, but since this sight appears to be predominately designed for use on the AR platform it seems like this should be the standard set up.
