Diana 4-16x40 AO IR — parallax-adjustable scope for air rifles

The scope has a one-piece 25.4 mm tube made of anodized aircraft-grade aluminum with a matte finish. Thanks to precise sealing and nitrogen filling, the optics are fog-resistant and weatherproof. The solid construction and compensating mount allow use on high-powered spring air rifles. Lenses are coated with an anti-reflective layer that improves light transmission and provides a bright, sharp target image, even in low-light conditions. The eyepiece features a ring for precise focus adjustment. The scope also has variable magnification 4-16×, allowing the shooter to choose between a wide field of view or a zoomed target image. The 40 mm objective ensures good brightness and comfortable shooting in low light.

Diana optical scopes — reliable scopes for air rifles

The Diana 4-16x40 scope uses a popular Duplex reticle consisting of 4 thick posts that transition into thin hairlines in the center. Duplex is one of the most popular reticles, allowing both precise and rapid shooting in varying lighting conditions. The reticle is adjusted with capped turrets with a click value of 0.25 MOA. The reticle can be illuminated red or green. The 40 mm objective ensures good brightness and comfortable shooting in low light. Adjustment clicks are clear and audible, allowing precise and efficient reticle correction.

The objective features a ring for smooth parallax compensation from 9.6 m to infinity. Parallax correction allows precise focus adjustment depending on the shooting distance. The scope comes with high mounting rings for an 11 mm rail, polymer lens covers, and an Allen key. Diana 4-16x40 AO IR can be used on spring-powered air rifles, CO₂ rifles, and ASG replicas.
