Anybody know where I can find a mount for a bipod on my HP 25 standard

If your rifle is the one on the picture, I would find a tube that can lose be over the cilinder, and try to fix it with rubber in the middle among the tube and the cilinder. The tube can be adapted to receive a swivel that could receive the bipod.

I do not know a piece in the market to fit your rifle.
