Yeah that should be the same as the BP-02
What's warped on it? Or could it have been machined wrong? These are usually quality mounts. Can you exchange it from the place you bought it from?
Your "smith" doesn't know what he's talking about, he must be comparing these to the UTG ones which are low quality. I don't know of any other mounts for the SVD/PSL style rail, most are made for the AK rail.
The scope your looking at is nice for the price, you don't have too many choices in that price range.
