Its not a Stock, I don't like using stocks as most of it is already made and most of the time Stock Sig makers use the stock as their one and only resource.

Anyway, the Stock isn't blurred, I don't see where its blurred at all, it must be our monitors... Sharpening is a bad idea, especially for this signature as it will make it separated, out of place and jagged.

The High Pass tip you gave me is nice, but theres no need for it on this signature, thanks for the tip, I'll use it in the future.
