The Centra Duo Vario for Walther (M18) is a precision-engineered adjustable front sight ring designed specifically for Walther rifles with an M18 front sight thread. Competitive shooters who demand versatile sight picture control will appreciate the Duo Vario’s ability to fine-tune the inner ring diameter, enabling optimal focus and target alignment under varying lighting conditions and range environments.

Unlike fixed sight rings, the Duo Vario allows shooters to customise the centring diameter, giving them enhanced flexibility and a personalised sight picture. This ensures a crisp and consistent aiming reference, whether you’re training at your home club or competing at high-level events.

In addition to its adjustable design, the Duo Vario is compatible with duplex iris elements and coloured filters (lenses), allowing for contrast enhancement and light control tailored to individual shooter preferences. Manufactured with Centra’s renowned quality and attention to detail, this ring is built for durability, repeatability, and precise performance that aligns with ISSF standards.
