Backlash“ is defined as the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence i.e. a gap, in the context of a rifle sight, the moving parts which carry the peep hole, to which your iris would be threaded, give rise to positional movement which directly effects the accuracy of each shot. In former times this was mainly caused by tolerances in machining. To make matters worse, the constant adjustment of sights by their nature and recoil of the rifle give way to wear and thus increase the amount of backlash present
The new 598S have an innovative new adjustment spindle with internally pressurized springs which make for high precision sight adjustment and makes the sight completely „Backlash“ free
Made from the best possible materials (alloy and stainless steel) which guarantees an ultra light weight and extremely durable rearsight
Internal parts are covered in a special anti-friction coating with the use of Molybdenum Disulfide and Teflon
Precision machined out of solid aluminium with minimal tolerances on state of the art CNC machines replacing less efficient pressure casting
Attractively anodised in a top quality anti-reflective matt silver finish for prolonged weather protection
Front and rear threads allow the use of an iris on the rear and an anti-glare tube on the front
Precision adjustment gives 1.5mm bullet shift per click at 50m
Individually numbered
Adjustment: Height: 11mm, side: 10mm
Iris thread is for typical European 9.5mm thread size
