The New Standard In Long Range Night Vision - FLIR Apollo | FLIR Systems

FLIR ThermoSight C-Series
Thermal Imaging Clip-On System

ThermoSight C-Series eliminates the requirement of removing the existing day scope from your rifle, to replace it with a dedicated thermal sight (which would also involve re-zeroing). The ThermoSight C-Series simply mounts in front of a standard daytime optical sight. Factory bore-sighted to tolerances of less than 1 MOA, no re-zeroing required. The ThermoSight C-Series saves the operator time and money with versatility.

Total mission flexibility

Made for hunters, SWAT teams, and military marksmen who want to use the daylight sniper scopes they're familiar with, but add thermal night vision capability, ThermoSight C-Series scopes give you the best of both worlds.

Reliable, flexible, easy to use

From MIL-STD-1913 Picatinny rail mounts with quick-release mechansinsm to user adjustable imaging controls and on-board video recording, ThermoSight C-Series scopes give you all the features you need.

Built to last

Built out of CNC-machined aluminum alloy that can stand up to extreme mission abuse, ThermoSight C-Series backs up its claims with a limited 3-year warranty and a full 10-year warranty on the infrared detector. All this, and the peace of mind that comes from knowing it was made in the USA.
