  But, are argon molecules larger than nitrogen?

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.

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.

      Not sure what you mean about "broad daylight" hunting? I just go when it's time to go.  Wink  As to "temperature transition"  times, I take a similarly simple approach to it by not considering it at all.  I do make a concession with my Winter predator rifles by not bringing them into a really warm area after hunting in cold weather....more for condensation on the rest of the gun that any optical considerations, though.
    I'm not poo-pooing scopes being purged at the factory. But as long as some sort of dry atmosphere is introduced,  I'm not convinced it makes any difference what it is. And the 'purged state' of a scope is not a forever thing. Seals leak due to age, we move the occular in and out on threads that are certainly not air tight (despite whatever sealing method is used), we move objective lenses with similar threads or via a side mounted turret (with seals) there's expansion/contraction due to heat and cold, etc. 
     As long as we don't have some sort of massive sealing issue, these things just keep on working for the most part.
     Good shootin'. Smile   -Al
