What it is best for

The TC50-640 is for hunters who want the best clip-on image and the most reach while keeping their day scope and zero. Ideal for long-range night shooting over open ground where detail at distance decides the shot.

Key features and specifications

• 640×512 high-sensitivity 12-micron thermal sensor
• 50 mm germanium lens for long-range detection
• Long detection range (the longest in the Rattler clip-on line)
• Mounts ahead of day scopes; QD Picatinny mount
• High-resolution OLED display, multiple palettes
• 16 GB storage, onboard recording and Wi-Fi
• Rechargeable battery with USB-C external power
• Waterproof, shockproof, 5-year warranty

Trade-offs and who it is not for

It is the most expensive Rattler clip-on, and the large 50 mm lens adds size and weight up front. If your ranges are short to medium, the 384 or 256 clip-ons are lighter and cheaper.

Pairs well with

• If you want a lighter, cheaper option: AGM Rattler TC35-384 Thermal Clip-On
• If you prefer a dedicated 640 scope: AGM Rattler TS50-640 Thermal Riflescope
• If you need a scanner too: Thermal Monoculars

FAQ

• Why choose a 640 clip-on over a 384? A 640 sensor shows more detail at a distance, which helps you identify game further out before the shot.
• Does a clip-on change my zero? No, mounted correctly, it works through your day scope’s existing zero and reticle.
• Is it effective for long range? Yes, the 50 mm lens and 640 sensor give it the most reach of the Rattler clip-ons.
