A specific Polarizing Filter End Cap with an integrated Polarizing Filter can be ordered. The

when sighting on bright, high temperature targets through the visual sighting port. The filter does not

achieve the desired visual attenuation.
Polarizing filter will not fit in the standard end cap. Do not look through the lens at
extremely bright objects with your eyes unprotected. Eye damage could occur.
