Maven B.5 18x56 Mil B51856MILBLD4 Black/Grey binoculars (B51856MILBLD4)

Designed specifically for shooters, the Maven B.5 MIL is our largest objective binocular, built for target and competitive shooting. It features an integrated fixed MIL reticle that provides clear shot interpretation for both shooters and spotters. The reticle allows for precise range estimation on known targets or quick field judging in real time. With 18x magnification, it offers an unobstructed, detailed view of the target, enabling fast and accurate adjustments for follow-up shots.

The B.5 MIL retains all the key qualities of the original B.5 model, including a durable yet lightweight magnesium frame and an advanced Abbe-Koenig prism system. Its large 56mm objective lens delivers exceptional brightness and clarity, enhanced by premium fluorite glass — the same high-end glass used in our S Series Spotting Scopes. This makes the B.5 MIL the ideal choice for those seeking a high-powered optic to elevate their shooting performance.

The binoculars deliver tack-sharp edge-to-edge clarity, crystal-clear optics, generous eye relief, and a smooth, precise focus mechanism for effortless use.

The Maven B Series represents our elite line of optics, engineered for exceptional performance at a fraction of the cost of comparable premium binoculars. Each model combines modern sportsman-inspired design with state-of-the-art materials and technology, creating a rugged, high-performance optic without compromise.

Included with the B.5 MIL are a neoprene neck strap, lens caps, and a double-layered microfiber storage bag.
