Sightmark latitude 10-40x60 - SightMark Latitude 10-40x60 F-Class Rifle Scope

Went into the store to buy a new vortex , sales man was good cond me into this sightmark. Got it home after having to buy new rings and base to fit the 34 mm tube. When I was leveling the scope I noticed the turrets where wrong. Mill turrets on an moa scope.(good catch QC ). So I shrugged that off and starting sending some down range. Horrible eye relief , parallax is way off. Any ways 3 shot group the size of a quarter out of my 300 rum at 200 yds . I thought ok I can deal with the imporfections. Moved out to 250 yds which is were I want this gun zeroed at. Make a couple slight windage adjustments and nothing. Made a couple more and nothing . One more time and wow jumped 6 inches off target. Tried to get it back and wouldn't ya know same results. Back and worth till I finally called it quits. 300 rum ammo is way to expensive to have a scope that acts like this. Called there customer service and wow what a joke. Taking it back to place I purchased it from to get my money back. Vortex razor gen 3 will be on it tomorrow. Which is what I originally wanted until I meet the used car salesmen and fell sucker for his bs. Won't happen again. Good luck guys and gals
