ARKEN EP-5 5-25X56 Gen-II FFP TOR MIL Reticle 34mm Riflescope

Building on the success of Arken's flagship EP series, the EP-5 GENII 5-25x56 FFP delivers upgraded glass, refined mechanics, and enhanced performance for precision-driven shooters at any distance.

Premium Japanese XED Glass & Refined Optical Architecture

With Japanese Extremely Extra-Low Dispersion (J-XED) glass and a refined optical system, the scope delivers exceptional edge-to-edge clarity, contrast, and fine detail throughout the 5-25x magnification range.

Instant Target Acquisition with a More Forgiving Eyebox

A larger ocular eyepiece provides 3.5″ of eye relief. The nearly 1.6″ lens and forgiving eyebox enable faster target acquisition and a consistent sight picture from virtually any shooting position.
