This is a very affordable P4 Sniper Scope for Air Guns and Rifles. The scope's magnification is 3x-9x and has objective DIA at 40mm and the Reticles illuminate in Red with multiple brightness settings. Why spend over $300 to buy a Rifle Scope when you only need to spend $35.00? You can upgrade this scope (please choose Option) to NcStar Model SEFB3940R which has Reticles that illuminate in Red with multiple brightness settings. The illumination will help you see better in dimmed area/situation.
