The 6-24x50 AO IR Blackhawk Rifle Scope by Barska has been designed to provide pin-point accuracy and rugged durability that you can depend on. Whether at the range or on the hunt, the 6-24x50 Blackhawk Rifle Scope puts your shots on the target with its precision optics. An Illuminated Red/Green Mil-Dot Reticle (IR) can be adjusted to 5 different levels of brightness, which allows the user to fine-tune the reticle for optimal performance in any lighting situation. An Adjustable Objective (AO) Lens allows for quick and easy Parallax Correction, while Fully Multi-Coated Optics help increase light transmission to produce an extremely clear image. Uncapped turrets allow for quick adjustments to the windage/elevation settings, which can then be locked into place to prevent any unintentional movement. The 6-24x50 Blackhawk Rifle Scope comes well-equipped with a number of advanced features at an unbeatable price, and is backed by Barska's Limited Lifetime Warranty.
