Description
The Rattler-C V2 50-640 is the 640 × 512 resolution member of AGM's second-generation clip-on family. The 12-micron VOx sensor and sub-20 mK sensitivity give it some of the cleanest thermal imagery AGM has shipped, pulling heat signatures out of darkness, fog, smoke, dust, rain, snow and brush at ranges up to 2600 meters. Stadiametric ranging, hot tracking, scene modes and automatic or manual flat-field correction are all built in.
Mounting is the easy part: the included ADM quick-release Picatinny mount sits the unit at a 1.5 inch centerline directly in front of your scope, so you keep your zero and your glass. To attach the clip-on directly to the objective of a day optic instead, add the optional Front Q-R Adapter (sold separately). Each unit ships with two NE-4400 rechargeable batteries for up to 9 hours of continuous use on a charge, and the USB-C port accepts any 5V power bank for all-night sits. The onboard Wi-Fi hotspot streams live video to the AGM Connect app and lets you pull recordings off the 16 GB internal storage without cables.
Featured Highlights

Day scope to thermal in seconds
The ADM mount clips the Rattler-C V2 onto any Picatinny rail ahead of your scope with no tools, and comes off just as fast so the same rifle runs day and night.

Sub-20 mK 12-micron core
The 640 × 512 VOx detector resolves small temperature differences, so animals stand out from cold ground and tree lines at distance instead of blending into noise.

Record, stream, share
Shot-activated recording saves the moment automatically. Video, audio and photos land on 16 GB of built-in storage, and the Wi-Fi hotspot streams live to your phone.

Built for the field
IP67 sealing, a 1000 g recoil rating and an operating range from -22°F to 131°F keep the unit working through rain, cold and heavy calibers.
