Waiting to play!!

My 7mm is together but can't mount the stock because I am missing the threaded stock screw stud and nut. This is a QB 78 conversion 3000 psi tube, 7 mm 33" TJ barrel, and a Richards Microfit tac-driver laminate stock.. I haven't been able to shoot a string yet (only 3 shots)... I think it will shoot Bob Sterne BBT's 94 grains at about 880 fps.. Trying to find the stud and slotted nut for the stock is proving to be a pia!!
