Arken SH4GII-4160VHR Matte Black 4-16x 50mm 34mm Tube Illuminated Red VHR MOA Reticle - SH4GII-4160VHR - 850083375102
Product Description
Precision long-range shooters often face severe optical compromise when balancing heavy elevation travel, structural maintube rigidity, and tracking repeatability against budget limits. Narrow 1-inch or 30mm scope tubes frequently restrict total internal elevation adjustment, forcing shooters to run high-incline scope bases or sacrifice extreme-distance dialing capabilities. The Arken Optics SH4 GEN II 4-16x50mm FFP Riflescope in VHR MOA (SH4GII-4160VHR) eliminates these elevation and tracking limitations by pairing a massive 34mm aircraft-grade aluminum maintube with ultra-reliable mechanical turrets and high-definition Japanese glass components.
Engineered for tactical precision, ELR bench-rest, and modern precision rifle matches, the SH4 Gen II features a First Focal Plane (FFP) glass-etched VHR MOA reticle with red illumination. Because the reticle scales proportionally across the 4x to 16x magnification range, reticle holdovers and windage subtensions remain mathematically accurate at every power setting. Built around Arken’s robust AZS (Arken Zero Stop) system, the exposed tactical turrets provide crisp, tactile click adjustments that return to your exact zero point without overrun or guesswork.
Finished in a durable matte black hardcoat anodizing, the SH4GII-4160VHR features side parallax adjustment from 25 yards to infinity, a wide 50mm objective lens for exceptional low-light light transmission, and nitrogen-purged waterproof, fogproof, and shockproof internal construction for unyielding performance under heavy magnum recoil.
*Armorer Bench Notes & Real-World Staging Guidance:
Mounting & Ring Compatibility Matrix: Requires 34mm scope rings or a 34mm one-piece cantilever mount. Ensure proper ring height clearance for the 50mm objective bell (typically Medium or High rings depending on barrel contour and rail inclination). Always verify eye relief and cheek weld setup prior to final torqueing.
Installation & Zero Stop Sequence:
- Mount the optic loosely into 34mm rings attached to your rifle's Picatinny scope base.
- Level the reticle precisely using a reticle leveling tool or plumb line, then torque ring cap screws in a cross pattern to manufacturer specs (typically 15–18 in-lbs).
- Bore sight the rifle at 100 yards, then perform live-fire zeroing using the turret controls.
- Once 100-yard zero is established, loosen the turret set screws, disengage the Arken Zero Stop (AZS) ring, set it firmly against the mechanical stop, and re-tighten the turret cap facing the zero index mark.
Key Features
