Bushnell’s Elite Tactical 3.5-21x50mm DMR3 Riflescope delivers excellent long-range performance in a small package. The overall optical design utilizes ED Prime glass equipped with FMC Elements and EXO Barrier Protection to deliver greater light transmission and protect from water or fogging. The 50mm objective lens produces superior image clarity and resolution, as well as a much more forgiving eyebox to promote faster target acquisition. The advanced optical design also offers a parallax adjustment of 25-yards to infinity, making the 3.5-21x50mm DMR3 Riflescope ideal for virtually any platform from rimfires to long-action magnum rifles. The elevation and windage turrets are exposed and feature bold, easy to read markings to allow the user to make quick adjustments in the field while under pressure or in low light environments. The elevation turret also features Bushnell’s exclusive RevLimiter Zero Stop for quickly and easily returning to zero after making adjustments. Another notable feature is the G4P Precision Reticle which was designed between Bushnell and G. A. Precision. It utilizes an ultra-fine floating-dot for a clean sight picture, with hashmarks and subtensions for accurately compensating for bullet drop and wind drift. In addition, the Elite Tactical 3.5-21x50mm DMR3 features a locking diopter to ensure you always have a sharp and clear picture of the reticle, and also prevents unintentional diopter adjustments.
