Has anyone come up with a way to mount a rail for bi-pod to stock with integrity? I presently use the saber bottle adapter but with the weight of night vision equipment the bottle adapter extension lets bottle flex up to almost touch barrel. Eventually the cover plate screw get loose and damages its threads. It is a very handy and light 70ft/lbs gun. Money does not hold me back if I could get a redesigned stock i would have it made. Guess I'm trying to say I like my little rifle and want to keep it.
