What are those? Mossys?
I once put a PG like that lower one on a Winchester Model 1200. I removed it immediately upon returning from shooting a half dozen rounds thru it configured in such a manner. Not only was it incredibly difficult to hit the broad side of a barn with such a PG, it had to be the most painful experience I've ever endured while shooting. A buddy shot it once, and he handed it back to me saying, "That's enough torture for me!" I did saw off an extra Model 12 stock I have for my Model 12, and with more of a bird's head type PG it's not nearly as painful and is quite manageable.
