Vortex Viper PST 4-16X50

Hello, 

I have a Vortex Viper PST 4-16X50 gen 1 rifle scope for sale. This has spent time on both my coyote rifle and my target 308. It tracks well and I have used it to 1000+ yards with my 308.  I don't have the original box as I purchased this scope well over 10 years ago. That said I recently purchased an almost identical HST version (the same minus the illumination) for my 22LR and will ship it in that box. The rings are MDT medium rings and retail for $175. There are some wear marks on the scope which I have tried to include as best as I could. The glass is still clear the illumination still works and the turrets still dial true and return to zero. I have installed shims for a "zero stop" (if you've used these scopes you know it's by no means a perfect zero stop) and I have spare shims as well. I'm asking $700 with the rings or $600 for the scope alone shipped.  The only reason I'm selling it is because a deal came up on a Schmidt and Bender that I couldn't refuse so those scope is now surplus to my needs. I would consider a trade for a range finder of similar value or a Garmin zero.
