Bushnell® AR Optics® 3-9x40mm Riflescope Drop Zone 223 SFP Reticle 1″ Maintube


SKU: BUSAR73940 Categories: ,

The classic 3-9×40 configuration meets the versatility of the AR Optics line in this do-all riflescope. It has target turrets and side parallax focus for precise adjustments. The scope features the Drop Zone-223 reticle, calibrated for .223 ammunition.

Bushnell’s aluminum 1” tube is the foundation for this rugged riflescope. Exposed turrets allow you to dial for windage and elevation adjustments quickly and accurately, and the 10-yard to infinity side parallax adjustment allows for fast and easy focusing. With an IPX7 waterproof rating, and fully multi-coated optics, this riflescope is an outstanding value.

  • Exposed Turrets

  • Side Focus Parallax
    • Side focus parallax goes down to 10 yards, so you’ll be able to take the close shots, as well as the long ones.
  • Waterproof Construction
    • Waterproof construction with a full IPX7 rating makes it so it won’t fog up, and you’ll always have a clear view.

  • The Drop Zone-223 Ballistic Reticle
    • Scopes equipped with the DROP ZONE-223 ballistic reticle are designed to be sighted-in at 100 yds, and provide aiming points in the shape of a dot every 100 yds, out to 500 yds. In addition, the top of the reticle’s bottom post (located below the 4th dot) represents a holdover point for a shot at 600 yds.
    • The Drop Zone 223 reticle is calibrated for use with 223 Rem/5.56 ammunition loaded with 55-62 grain bullets.  All AR Optics scopes must also be turned to the highest magnification setting in order for the reticle’s ballistic feature to function properly. The 4.5-18x 40mm models should be set at 18 power for proper ballistic reticle performance.
