I have a 6 or 7 year old shotgun/muzzleloader heavy duplex on my mk85. Back then I really don't think it had a vx1 or vx2 designation. It is in my opinion the best muzzleloading scope out there. I bought it for around 249 from a company in Pa that is no longer in business or has changed their web site. My scope has great optics and is solidly built. I would believe the new ones are as good.If it were me I would go new from optic planets.
