Swift 2x Pistol Scope

I was thinking about a 2x Swift for one of my Crosman 600s. I have been buying most of my scopes from Opticplanet for the last 5 years, but can't under stand this price difference? Maybe I am missing something? Has anyone on here ever done business with Thesportsmoneky?

Kev, I have two, the one works, the other one doesn't. I needed to get it rebuild and did not want to do it myself, so I just sent it to Mac1. Figured while they had it just as well have them put a scope rail/base on it. I am not sure exactly how he does it? One of my friends whom I sold a 2x Leupold to 10 years back, might sell it back to me, if not I will need a scope. The one thing I did notice on the specs for the Swift, was a 12" inch eye relief, that can't be right can it. How is yours? I think my Leupolds were 18 or so. I could kick myself, I had several scoped PB pistols & sold them about a decade ago and let the scopes go along. Still trying to figure the price difference, something can't be right.
