What it is best for

The TS50-640 is for long-range night hunters who need to detect and identify game well downrange. The 640 sensor and 50 mm lens deliver the detail and reach for open country, while the scope still doubles as a capable handheld scanner.

Trade-offs and who it is not for

It is the most expensive Rattler scope, and the 50 mm lens narrows the field of view versus shorter models. If your ranges are short to medium, the 384 model is lighter, wider, and cheaper.

Pairs well with

• If you want a wider, cheaper option: AGM Rattler TS35-384 Thermal Riflescope
• If you want to keep your day scope AGM Rattler TC50-640 Thermal Clip-On
• If you want a rangefinder built in: ThermTec Ares 650 LRF 2.0 Thermal Riflescope

FAQ

• Is a 640 scope worth it over a 384? If you shoot at a distance and need to identify game far out, yes; for shorter ranges a 384 is plenty.
