Redding balance beam scale .Scott Parker is well known in the shooting world for tuning balance beams to get the very most you can from them . I can tell a difference of a kernel of Varget on this beam scale . I'm including my Logitech HD C525 Webcam with USB cable so you can monitor the scale from your computer monitor + a dust cover . This beam is in excellent condition feel free to ask any questions . 130.00 to your door in the USA.
