I have a Vortex Spitfire 3X on a .223, a Diamondback HP on a .308, and a Strike Eagle 1-8x24 on a .300 BLK pistol I just built. I can't say a bad thing about any of them. I'm in the process of putting together a .30-06 and it will also have a Vortex on top of it. I also just purchased their Ranger 1300 range finder. Their lifetime warranty even covers the electronic side of the range finder. They put a post on instagram showing a guys binoculars that he dropped in a fire and they replaced them without question. Also, if you have any kind of Public Service affiliation, Optics Planet will give you 40% off MSRP for Vortex. You have to call them to get this pricing.
