Gehmann 598S Precision Rearsight Dioptre

GEHMANN 598S PRECISION REARSIGHT DIOPTRE

The Gehmann 598S is a high-precision rearsight dioptre engineered for serious target shooters who demand zero tolerance and absolute reliability. Developed with an innovative adjustment spindle design, it features internally pressurised springs that completely eliminate backlash—the mechanical play that traditionally affects sight accuracy due to tolerances and wear.

Crafted from aircraft-grade aluminium and stainless steel, this rearsight is not only ultra-lightweight but also incredibly durable, with a premium matte silver anodised finish for maximum weather and reflection resistance. Internals are coated with a special anti-friction blend of Molybdenum Disulfide and Teflon, ensuring smooth operation throughout its lifetime.

Unlike older designs reliant on pressure casting, the 598S is precision CNC machined from solid billet with minimal tolerances. It includes standard threads to accommodate a rear iris and a front anti-glare tube, making it a truly versatile upgrade for your competition rifle setup.
