Just looking to see if anyone has used these guys for a aftermarjet stock for your CZ?
Staffordshire Synthetic Stocks - Firearms Custom Work

It looks like they have a mcmillan a style and aics style for any rimfire. Just wondering if they are stiff enough to support shooting from a bipod?

The only thing I found on them is on a british airgun page and that they run 320 bucks or so.
