Whether your hunt takes you to sub-zero temperatures in the Arctic or the heat and humidity of the Everglades, you never have to worry about your Aimpoint sight fogging up.
On any caliber
Since every Aimpoint sight is made for use in the real world, they can be mounted on virtually any type of firearm in any caliber that you can imagine.
