I have two of these - this one was on a .22 rimfire rifle I'm getting ready to sell. I don't have to sell it so low ball offers will be ignored. That said, this is a First Focal Plane (FFP) optic. The tube diameter is 34mm. The objective is 56mm so it lets in a LOT of light. This one has the EBR-7C (MOA) reticle. Parallax will adjust down to 15 yards so it makes a great small bore scope. It also comes with a sun shade. Retail on these is 1,149.99.
NOTE: Vortex offers a no B.S. lifetime warranty so it doesn't matter that you will be the second owner - anything happens they will replace it no questions asked.
