The Arken SH-4 GEN II 4-16x50 FFP VPR MIL is a first focal plane optical sight engineered for long-range target shooting, PRS/NRL competition, and stationary hunting platforms. Built around a robust 34 mm main tube, it houses Arken's high-definition (HD) fully multi-coated glass and an etched VPR MIL reticle with red illumination across 6 intensity levels. The scope features a mechanical turret tracking system with 0.1 MIL clicks, an Arken Zero Stop (AZS) mechanism, and a broad 36 MIL elevation adjustment range capable of handling extreme long-range bullet drop.

Key Features

• First Focal Plane (FFP) VPR MIL Reticle: Reticle scale remains proportional across the entire 4–16x magnification range for consistent holdovers and ranging at any zoom level.
• High-Capacity 34 mm Tube: Aircraft-grade aluminium housing accommodates a wide 36 MIL total elevation travel and 10–14 MIL windage travel with 8 MIL per turret revolution.
• Arken Zero Stop (AZS): Integrated mechanical stop provides a positive, repeatable return to your set zero after dialling elevation changes.
• Side Focus Parallax: Adjustable parallax dial sharpens focus and eliminates reticle drift from 25 yards (22.8 m) out to infinity.
• Heavy-Recoil Construction: Nitrogen-purged, O-ring sealed waterproof and fogproof assembly tested to withstand recoil up to .50 BMG.

Who is the Arken SH-4 GEN II 4-16x50 FFP VPR MIL Rifle Scope for?

• Precision Rifle Series and NRL22 Competitors — Delivers 36 MIL of total internal elevation travel within a 34 mm main tube, giving precision rifle scope users the mechanical tracking and dialling range required for engaging multi-distance stages.
• Long-Range Tactical Target Shooters — Combines 4-16x magnification with a 50 mm objective lens and a 0.1 MIL click first focal plane reticle, ensuring accurate holdovers and target resolution at distances extending past 1,000 yards.
• Stationary and Varmint Hunters — Provides a heavy 35.6 oz (1,009 g) stable optic platform paired with illuminated red aiming marks, optimising bench, blind, or tripod-based shooting against small targets.

Less suitable for: Mobile backcountry and alpine stalking hunters requiring an ultralight setup under 20–24 oz due to the scope's 35.6 oz weight, as well as extreme close-quarters shooters engaging targets under 25 yards who require a dedicated close-range optic focusing down to 10–15 yards to prevent parallax optical blur.
