Rare Military and Police Rifle scope

This is a SEILER INSTRUMENT sniper scope formerly not available to the public. It has a 30mm tube   This scope is very robust in its construction and designed for rough handling. The eyepiece is quick detachable and can be replaced with a night vision assembly which I don’t have. I don’t know much about it and have had it on my 22 magnum with no issues whatsoever. I’m clearing out the stable somewhat. The rings are included and are very heavy duty as well.
