6 Months of Use and Abuse | Contractor 640
This 6-month review of the Armasight Contractor 640 thermal optic highlights its reliability, excellent zero retention with the KDG mount, and superior identification capabilities due to its 640-base sensor. The speaker details practical usage, including cosmetic wear, a torn objective lens cover, low battery behavior, and a persistent video file corruption issue. Recommendations are made for battery management and utilizing the turret locking feature.
