Hey guys, I have a buddy who wants to sell off his collapsible stock with the PDW-length recoil spring. I don't actually own a PDW, but I probably will eventually, and it's a good price.

I want to know if I can put the stock on my full-sized PTR to see how it feels when firing, because the reason my friend is selling it is because he hates it. Am I going to damage anything?

I'd be worried you might cause roller marks with extended use.
