The InfiRay Clip T Series CTP13 Thermal Imaging Clip-On
is an ultracompact and waterproof day scope attachment. It fits any
Picatinny rail mount, and no re-zeroing is required. The clip-on needs
absolutely no light to function, so it allows you to turn any day scope
into a night vision scope with a simple throw lever mount. With the
CTP13, you can see your targets any time, day or night.
