Bushnell AR Optics 4.5-18x40

• 4.5-18x magnification range: This zoom span covers everything from close-to-medium target work to more deliberate shots at distance, so the scope remains useful on AR-platform rifles set up for varminting, rimfire precision, or general range use.
• Side-focus parallax adjustment: Adjustable parallax from 9,14 m to inf helps keep the target and reticle on the same focal plane, which makes precise aiming easier as distances change and reduces aiming error at higher magnification.
• Fully multicoated optics: The lens coatings improve light transmission and contrast, giving a clearer sight picture in mixed light and helping the shooter pick up small targets or aiming points more confidently.
• Tactical turrets with 50 MOA travel: The exposed-style turret layout gives quick access to elevation and windage corrections, which suits shooters who dial for distance instead of relying only on holdover marks.
• IPX-7 waterproof, fogproof, shockproof build: The sealed 1-inch riflescope body is made for field use in rain, temperature changes, and repeated recoil, so zero and visibility are easier to maintain in practical outdoor conditions.

About the Bushnell AR Optics Series

Bushnell AR Optics was developed around the needs of AR-15 and AR-10 compatible modern sporting rifles, with an emphasis on a low-profile design and a wide field of view. Within Bushnell’s lineup, the series sits as a practical bridge between basic sporting optics and more specialized tactical models, giving shooters a purpose-built riflescope family for carbines and precision-oriented AR setups. The range covers everything from 1-4x to 4.5-18x, so the series supports fast handling at short distance as well as more measured shooting from the bench or in the field.

Across the line, Bushnell offered multiple reticle patterns and focal-plane configurations to match different cartridges and shooting styles, including BDC-oriented designs intended to simplify elevation holds. The series is also known for fully multi-coated lenses and Bushnell’s use of high-definition glass in the family, helping deliver a clean, usable image without adding unnecessary bulk. A defining mechanical detail in the series is the Throw Down PCL power-change lever, which was designed to make magnification changes faster and easier when the rifle is shouldered or when shooting positions change.

About the Bushnell AR Optics 4.5-18x40

The Bushnell AR Optics 4.5-18x40 is the higher-magnification end of the AR Optics family, built for shooters who want an AR-platform riflescope that can stretch beyond short-range carbine work. Its 4.5-18x magnification range gives enough low-end flexibility for general target engagement while providing the top-end detail needed for small targets, rimfire precision, and varmint-style shooting where exact shot placement matters. The 40.00 mm objective lens keeps the scope compact enough for practical rifle setups while still supporting a bright, usable image across the zoom range.

This model uses a second focal plane reticle, which keeps the reticle’s apparent size consistent as magnification changes. In practice, that gives a familiar sight picture at every power setting and can make fine aiming less visually busy at high magnification. Because the reticle is non-illuminated, the scope stays mechanically simple and well suited to daylight range use and hunting in normal light conditions. The side-focus parallax adjustment is especially important on a scope with 18x top magnification, as it helps sharpen the image and reduce point-of-aim error when moving between nearer and more distant targets.

The mechanical layout also supports deliberate shooting. Tactical turrets with 50.00 MOA of elevation and windage travel allow visible, repeatable corrections for distance and wind, while the CCW rotation direction will feel familiar to many shooters who prefer that dialing pattern. A 90.00 mm eye relief helps maintain a comfortable head position, and the fast-focus eyepiece speeds up reticle sharpening to the shooter’s eye. With its 25.4 mm tube, IPX-7 waterproof construction, fogproof sealing, and shockproof build, this Bushnell riflescope is configured for regular use on modern sporting rifles without becoming oversized or overly complex.

About Bushnell

Bushnell was founded in 1948 by Dave Bushnell. The company grew from optical retail roots connected to a photographic shop in Pasadena, California, and it went on to become a well-known name in sports optics and outdoor equipment. Bushnell’s catalog has long covered the core categories that matter to hunters, target shooters, and field users, including binoculars, riflescopes, red dot sights, rangefinders, spotting scopes, and trail cameras.

In practical terms, Bushnell’s reputation in this segment comes from offering a broad spread of optics for different budgets and applications rather than focusing on a single niche. Its product families include Legend, Prime, Elite Tactical, and AR Optics, showing the brand’s reach from general outdoor observation to more shooting-specific platforms. Bushnell has also developed proprietary optical features such as EXO Barrier, a lens coating intended to shed water, oil, dust, and debris, reflecting the company’s emphasis on field durability as well as usable optical performance.
