The new PROSTAFF Target EFR (Extended Focus Range) 3-9x40 is designed and engineered for .22 LR, Air Rifle and other applications where the versatility of focusing at extended ranges-both close and distant-is desired. The Target EFR features an adjustable objective lens that allows focusing from 10 yards to infinity and the new Nikon Precision Reticle. Like other riflescopes in the PROSTAFF line, the new Target EFR takes advantage of Nikon's latest optical and mechanical technologies and can be fully optimized for virtually any ammunition or load with Spot On™ Ballistic Match Technology.
Fully Multicoated Optical System
Provides optimum light transmission and maximum brightness from dawn to dusk.
To simplify field adjustments, Nikon has integrated this feature into all new riflescopes. Just sight-in as usual, then lift the spring-loaded adjustment knob, rotate to your “zero”, and reengage. Field adjustments are now as simple as dialing-in your subsequent ranges.
Nitrogen filled and O-ring sealed.
Quick Focus Eyepiece
Allows the shooter to instantly bring the reticle into sharp focus.
