Arken Optics SH4 4-16X50 GEN2 FFP VPR MIL Illuminated Rifle Scope

The Arken SH-4 Gen II is a precision-built first focal plane rifle scope offering high-end features at a very accessible price point. With rugged construction, crystal-clear glass, and advanced turret tracking, it’s an ideal optic for shooters who want performance without overspending.

Offering a 4× to 16× zoom range, this scope is well-suited for everything from mid-range shooting to serious long-range target work. The 50 mm objective lens ensures excellent light transmission across the zoom range, and the first focal plane VPR reticle (available in MIL or MOA) allows accurate holdovers and range estimation at any magnification.

This model includes a red illuminated reticle with adjustable brightness levels, making it particularly effective in low-light or shaded shooting environments. The AZS Zero-Stop turret system ensures quick, repeatable return-to-zero function – ideal for shooters dialing for distance.

Turret adjustments are crisp and tactile, offering 0.1 MIL (or ¼ MOA) increments, with 8 MIL per revolution and up to 36 MIL of total elevation travel. The side parallax knob adjusts from 25 yards to infinity for fine focus, and the 34 mm tube provides generous internal adjustment range and enhanced durability.

Built from aircraft-grade aluminium and nitrogen-purged, the SH-4 Gen II is waterproof, fog-proof, and shock-resistant – capable of handling calibres up to .50 BMG. It weighs approximately 1,009 grams and measures around 340 mm in length, with consistent 91 mm eye relief across the zoom range.

Buyer Questions Answered

What kind of reticle does it have?
The VPR reticle comes in your choice of MIL or MOA formats, both illuminated and etched in the first focal plane – ideal for ranging and holdovers at any zoom level.

Can it handle heavy recoil?
Yes. The scope is shock-rated for recoil as strong as .50 BMG, and performs well on calibres such as .308, 6.5 Creedmoor, and .300 Win Mag.

Is the zero-stop reliable?
Very. The AZS Zero-Stop system allows for fast and consistent return to zero, helping avoid accidental over-adjustments.

Does the turret layout feel intuitive?
The turrets are clear and responsive. Some users note that 8 MIL per rotation takes getting used to compared to 10 MIL systems, but tracking is precise.

Is the eye box tight at higher zoom?
At 16×, the eye box is slightly more sensitive – common in this class of scope – but image quality remains high with correct positioning.

Is it suitable for tactical and hunting use?
Yes. The SH-4 Gen II is versatile enough for tactical training, PRS-style competitions, and hunting at varied distances. It’s built tough and tracks reliably.

Any mounting concerns?
The lower turret box may require slightly taller rings with certain monoblock mounts – easily resolved with the right hardware.
