Primary Arms Red Dots in cold/wet weather

[Severian]

Is there anyone running Primary Arms red dots (specifically the Adv. Micro Dot) in adverse outdoor conditions? NOT just an hour or two at a covered range. I actually use my rifles for extended periods outdoors in cold and wet mountain/forest conditions in the PNW, which may dip below freezing to zero at night. Rain, snow, fogging, creek crossings, ice, the occasional unfortunate drop, etc is typical and expected.

I'm wondering how well the Primary Arms optics hold up in these environments, compared to more expensive brands. I have Aimpoints on other rifles but I'm curious if I can get away with saving 1/3 of the optic cost on my latest AK build. The Primary Arms optics seem to get excellent reviews but I'm wondering how many of these people actually expose their rifles to more "real-world" northern conditions.

Manufacturer listed operation temperature ratings:

• Aimpoint T2: -45°C to +71°C (-49°F to +160°F)
• Primary Arms Advanced Micro Dot: 4 °F and 122 °F (-10°C to 50°C)
