Bisley SP1 Fixed Spirit Level for Scope Mounts brand_-American Hunter 22 calibre cartridgesThe Bisley SP1 is a fixed spirit level designed to fit 1" (25mm) scope mounts made by Sportsmatch. It bridges over the top of the mount and fixes to the lower mount cradle, giving an instant visual check that the rifle is level rather than canted. Canting, even a slight lean of the rifle off vertical, throws windage and elevation off at range, so a quick glance at the bubble before the shot helps keep the rifle true and supports consistent long range
