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.

Ideal for range work, hunting, and mid- to long-range shooting where control and repeatability matter most.
TOR | Extreme Competition
A dense 16 MIL holdover grid designed for maximum elevation holds without dialing.
-
0.2 MIL subtensions: Higher-density reference spacing for enhanced wind and impact correction
-
0.05–0.08 MIL floating center dot: Optimized for extreme-distance target definition
-
Fully illuminated reticle: Improved visibility and aiming precision
Built for PRS/NRL competition and rimfire precision shooting where extended elevation range and fine aiming control are critical.
Dial with Confidence
Precision-machined tactile turrets deliver repeatable tracking you can trust shot after shot.
