I don't personally know of any quality scope that comes with it's own mounts. How in the world could the manufacturer ever know what you intended to mount it on? Remingtons are different from Winchesters who are different from Rugers, who are different from Savage, etc., etc.
You buy the scope, and then you buy the mounts to fit the gun. The only variatin to the rule that I can think of is if you bought a package deal, gun, scope and mounts pre-assembled.
If you want a decent scope, I advise you to stick to the names that are and have been famous for years for their performance and reliability. Then get a GOOD set of name-brand mounts that aren't crap and have the both professionally installed.
Please don't buy junk. It is only a waste of your money, as you will be disappointed, and end up buying good stuff later on, anyhow after you've already wasted your money.
