I've had two Nikons, a 2-10x and a 2-7x. I wasn't able to get a good zero with the 2-10x but I also couldnt get a good eye relief either and never figured out why. Never shot on the 2-7x, furlough kicked in and I needed some cash flow. I really like the clarity of my 1-4x and I like the reticle, I just need to get a day that I can go zero it. Plus the center dot is illuminated, if ever it is needed for zombies in the woods at night.
I don't think you will find a Primary Arms in a local shop unless it is a consignment. Usually you will find them direct from PA, Rainier Arms carries their stuff, or on AR15.com from private sellers. I do know if their product has a defect or malfunction due to the scope, Primary Arms will send a replacement before you send the bad one back, and if they show something in stock, it arrives within 3 or 4 days. On my budget, they are the best bang for the buck. As stated above, their red dot 1x optics get great reviews wherever you look.
