Give your rifle a huge boost in accuracy with the Barska 1-6x 24mm Level HD FFP Rifle Scope. The rifle scope features a First Focal Plane (FFP) Illuminated HRS MOA Reticle, which allows for accurate MOA measurements throughout all other magnifications for quick target acquisition. This Illuminated HRS MOA Reticle (IR) on the rifle scope can also be switched to either a red or green reticle with adjustable brightness settings for accurate targeting in any lighting situation with impressive viewing clarity. This rifle scope is purged with argon gas to prevent internal fogging, even in extremely cold weather, and is coated with phase 3 hard anodizing to prevent scratching. The rifle scope's solid mono-tube construction helps protect the internal optics from shock and impact. This rifle scope is built to withstand recoil from AR-15 sporting rifles up to large caliber hunting rifles.
