Arken EP-5 GENII 5-25×56 FFP

Premium Japanese XED Glass & Refined Optical Architecture

The EP-5 GENII 5-25×56 FFP scope is built around upgraded Japanese Extremely Extra-Low Dispersion (J-XED) glass. Compared to the previous Japanese Extra-Low Dispersion (J-ED) glass, it further reduces chromatic aberration and preserves fine detail at distance.

Combined with a refined optical design, this scope delivers consistent performance across the entire 5–25x magnification range.

More Forgiving Eyebox, Instant Target Acquisition

Upgraded to nearly 1.6 inches, the new eyepiece paired with a 3.5-inch eye relief delivers a more forgiving eyebox, enabling faster target acquisition and improved stability under recoil.

A full sight picture is retained when shooting from prone, barricades, or off-angle positions with limited head mobility.

True Edge-to-Edge Clarity

A redesigned optical path reduces field curvature and edge distortion, delivering a sharper, more uniform image from center to edge, even at high magnification.

Choose Your Reticle: VPR / TOR

VPR | Classic Precision

A 12 MIL holdover grid designed for precise holds, wind calls, and faster follow-up shot corrections.

• 5 MIL subtensions: Clean reference spacing for fast, intuitive holds
• 04–0.08 MIL floating center dot: Low-profile aiming point designed for minimal target obstruction

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.

• 2 MIL subtensions: Higher-density reference spacing for enhanced wind and impact correction
• 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.

Arken Zero Stop: Repeatable Return to Zero

The Arken Zero Stop (AZS) system provides a positive stop after multiple full turret rotations, enabling a fast and reliable return to zero.

Every Detail Engineered for the Harshest Environments

6063 Aircraft-Grade Aluminum Construction: Machined from a solid block of 6063 aircraft-grade aluminum for the strength and rigidity needed to withstand years of hard field use.

.50 BMG Recoil Rated: Built to endure repeated punishment from heavy-recoiling rifles while maintaining dependable performance shot after shot.

IP67 Waterproof & Dustproof: Fully sealed against fine dust and heavy rain, maintaining reliable performance through muddy hunts, wet match days, and demanding field conditions.

Nitrogen-Purged Fog Resistance: Inert nitrogen filling helps prevent internal fogging and keeps the optical system clear in extreme temperature shifts and high humidity environments.

From Rimfire to Long Range

With parallax adjustment down to 20 yards and precision tracking for extended distances, the EP-5 GENII 5-25×56 FFP scope is equally at home on an NRL22 rifle, a PRS competition rig, or a dedicated long-range setup.
