has anyone heard of this before? i was under the impression the only mil spec versions were based off of the f1 models, but i came accross one for sale online. what actually makes it milspec?
The Mil-Spec is a completely different product line. There are more construction changes than just a glued in reticle, as well as a more extensive QC process than even a normal NXS gets.
There are Mil-Spec 5.5-22xs out there, mainly for use on the Mark 13 .300 WM rifles.
