Arken Optics SH4 GEN2 4-16X50 FFP Rifle Scope - Versatile Precision

In this review the Arken Optics SH4 GEN2 4-16X50 is evaluated for shooters seeking a versatile first focal plane scope that spans close to long range work. The bottom line is that this scope delivers clear glass, reliable adjustments and a rugged zero stop system for the price-conscious shooter who needs repeatable performance; its best attribute is the combination of a fully multi-coated 50mm objective and an AZS zero stop that together provide bright, accurate shots and a fast, dependable return to zero after field changes.

Key Features

• First Focal Plane Reticle: The FFP Christmas-tree style reticle maintains accurate subtensions across the 4-16X range so holdovers and holds are consistent at any magnification.
• AZS Zero Stop System: The simple, rugged zero stop mechanism allows a fast and reliable return to zero after dialing back from extended elevation adjustments.
• Fully Multi-Coated Lenses: Fully multi-coated optics maximize light transmission for improved clarity and low-light performance through the 50mm objective.
• Side Parallax Adjustment: The side knob parallax adjust offers visible range numbers and quick in-position correction for shooters engaging targets at varied distances.
• Durable Single-Piece Tube: Constructed from aircraft grade aluminum with O-ring seals and nitrogen purge, the single-piece 34mm tube is waterproof, fogproof and shock resistant.
• Illuminated Center Dot: The illuminated center dot provides precise aiming in low light while the fast focus eyepiece keeps the reticle sharp.

Who It's For

The SH4 GEN2 is aimed at hunters, tactical shooters and precision hobbyists who want a single scope that covers short to extended ranges without switching optics, especially those who value a first focal plane reticle for holdover use. It is also suitable for shooters who appreciate tactile, audible turret detents and a clear parallax scale for quick range adjustment.

Users who need an ultra-lightweight setup or who prefer minimal turret size for extremely compact rigs may want to compare other models, since some customers note the scope is on the larger side and has prominent turrets that add bulk and weight to the rifle.

Pros & Cons

• AZS zero stop and illuminated reticle combine for fast return to zero and precise aiming in varied light.
