I may be wrong but my understanding is that no matter what type of gas is used it's sole purpose is to eliminate any moisture as it is assembled from the factory. I'm not sure that whatever type is used actually stops fogging in itself. So in my way of thinking it really shouldn't matter whether nitrogen or argon is used so long as the process eliminates any moisture at the assembly process. I do, however applaud Leupold for tying something new to help the problem of internal fogging regardless of whether it is significantly better than the old standby of plain old nitrogen. One of the things I do that I think helps when hunting in extremely cold temps is to keep my rifles and bino's outside in a vehicle which I think that what Leupold is referring to when they advertise "thermal shock" meaning taking your scopes and bino's from a warm hunting camp directly into extremely cold temps. I think that this helps more so than whatever type of gas that is used to seal the optic.

hope no-one knows your addresses! I found out the hard way, leaving expensive guns outside is a good way to lose them, weather they are in a locked vehicle or not! |

Argon is an element and compared to elemental nitrogen, has almost three times the atomic mass. Argon also has one more electron shell and as already mentioned, is inert and non-reactive. Nitrogen is very reactive and this may be the reason for argon purging. Other than that, I am clueless on the reason. I also applaud Leupold for using Argon. |

I keep mine outside in extreme cold, too. This is for both the optics and the "high tech" lubricants. If argon helps in this regard for optics, I'm all for it. I would like to see actual experience with it. I would never leave a gun in my car in downtown Detroit. I digress, though. |

Nitrogen atoms are very reactive. Nitrogen molecules (which is what nitrogen gas is made of) are very stable. And are bigger in size than argon atoms. I posted this earlier in the thread. ILya |
