A couple of months ago I got a chance to shoot a rifle with a high end tactical stock that had a quick adjust monopod near the butt stock. I don't remember the brand of the stock but it was sweet! I am looking to outfit a Savage rifle with a similar set up. It was adjustable by twisting the grip and had a fast adjustment rate. I would say that one rotation moved the screw up around 1/2" I have found the Accu Shot Precision Stud Mount Locking Monopod BT04QK | eBay that looks like it would work. Does anyone know of or have other recommendations for after market rear monopods?
