ARKEN SH4GII-4161VPR VPR 4-16X FFP 34MM MRAD - SHIPS FROM SPORTS SOUTH
ARKEN OPTICS SH-4 GENII 4-16x50 FFP RIFLE SCOPE — VPR ILLUMINATED / MRAD TURRETS / 34mm
The Arken Optics SH-4 GENII 4-16x50 FFP VPR MRAD (SH4GII-4161VPR) combines the SH-4 GENII platform with the Variable Precision Reticle (VPR) and MRAD-graduated turrets in the cleanest possible configuration: MIL reticle, MIL turrets, no conversion between the two. The VPR is a first focal plane MIL grid for precision ranging, holdovers, and wind calls. At 0.1 MIL per click, every correction read from the reticle goes directly onto the turret — a 4.5 MIL elevation input is 45 clicks, end to end in the same unit.
The SH-4 GENII delivers 36 MIL of total elevation travel — 360 clicks across 4.5 revolutions of 8 MIL each — and 14 MIL of windage travel, both figures that exceed many 6-24x counterparts at this price point. The AZS (Arken Zero Stop) system anchors return to zero, and the sunshade is included. At 4-16x magnification and 35.6 oz on a 13.4-inch platform, the SH4GII-4161VPR is a compact, capable package for precision rifle shooters, hunters who run ballistic data in MIL, and competitors who need repeatable, methodical long-range performance without the weight penalty of a larger tube platform.
At 0.1 MIL per click across 4.5 full revolutions of 8 MIL each, the SH4GII-4161VPR has 360 elevation clicks from stop to stop. This is a substantial travel budget for a 4-16x scope, exceeding many 6-24x platforms. Shooters running a 20 MOA canted rail can reserve all or most of this travel for above-zero dialing, keeping the full range accessible without chasing zero into the middle of the adjustment.
The VPR’s MIL subtensions and the 0.1 MIL turret clicks share the same unit throughout. Range a target, read a drop, dial the number. A ballistic app set to MIL output feeds directly into the turret without conversion. For competitive precision rifle, where round-count per stage demands fast and accurate dialing, eliminating the MOA conversion step reduces one consistent source of field error.
With 14 MIL of windage adjustment available, the SH-4 GENII MRAD can accommodate extreme offset zeroing on heavily canted rails, significant crosswind adjustments, or mounting in rings that are not perfectly aligned. Most precision shooters zero windage at the bench and use the VPR’s horizontal subtensions for wind holds in the field, but the available windage travel provides substantial headroom for any configuration.
At 4x low power, the SH-4 GENII delivers a 30-foot field of view at 100 yards — useful for transitions, moving targets, or situational awareness in tight terrain. At 16x, the 50mm objective provides the light-gathering to support a clean image on a VPR precision grid for methodical long-range engagement. The 13.4-inch length and 35.6 oz weight make this one of the more compact 34mm FFP precision platforms available at this price.

The SH-4 GENII elevation turret increases elevation with counter-clockwise rotation, consistent with the Arken EP and SH series. This is opposite to many common production scopes where clockwise is up. Confirm direction during your first zeroing session. The AZS stop is reached by rotating clockwise back to the stop after dialing up corrections.
The AZS system provides a positive mechanical stop at the elevation zero position. After zeroing the rifle, set the AZS stop to lock that position. Dial up as far as needed for distance work, then rotate back clockwise to the stop to return to zero — no click counting, no under- or over-running. The stop is toolless. Zero reset is also available to re-mark the turret face without disturbing the AZS stop setting.
The sunshade threads onto the 50mm objective bell to reduce glare and lens flare in direct or oblique sunlight. Particularly useful during dawn and dusk engagements or when shooting across open terrain with the sun low and behind the shooter. Attach or remove without affecting zero.
Frequently Asked Questions
What is the SH-4 GENII and how does it differ from the SH-4J?
The SH-4 GENII (SH4GII) and SH-4J are separate SH-4 series variants from Arken Optics, each offering different specifications to suit different applications. The SH4GII-4161VPR is a 4-16x scope with 36 MIL of elevation and 14 MIL of windage, in a 13.4-inch, 35.6 oz package. The SH-4J is a 6-24x scope with 32 MIL elevation and 10 MIL windage at 14.1 inches and 36.6 oz. The GENII offers more elevation and windage travel despite being a lower-magnification, shorter, and lighter platform. The SH-4J offers higher maximum magnification for targets where 16x is a limiting factor. Both carry the AZS zero stop, 34mm tube, and Arken’s FFP construction.
Why does this 4-16x scope have more elevation than some 6-24x scopes?
Total elevation travel is a function of the scope’s mechanical and optical design, not directly of magnification range. The SH-4 GENII’s 34mm tube and internal layout deliver 36 MIL of elevation and 14 MIL of windage. A 4-16x scope with more internal travel than a 6-24x is not unusual when the optical designs are engineered differently. For shooters who prioritize maximum dialing range — particularly at distances where 16x is sufficient — the SH4GII-4161VPR’s travel budget can be an advantage over higher-magnification options with less adjustment range.
What rings fit the SH-4 GENII 4-16x50?
The SH4GII-4161VPR requires 34mm scope rings or a 34mm one-piece mount. Standard 30mm rings are not compatible. At 13.4 inches and 50mm objective, ring selection should account for barrel clearance appropriate to your receiver height and barrel profile. A 20 MOA canted Picatinny rail is a common pairing for precision applications, shifting the zero point lower in the adjustment range to maximize the usable portion of the 36 MIL elevation travel above zero for extended-distance dialing.
Is the battery included?
No. The SH-4 GENII uses a CR2032 coin cell for center illumination of the VPR reticle, which is not included. The sunshade is included. The scope operates fully as a non-illuminated FFP scope without the battery in any condition where the reticle is visible against the target.
What is the difference between VPR and VHR on the SH-4 GENII?
The VPR (Variable Precision Reticle) is a full MIL grid built for precision work: ranging using MIL subtensions, precise wind estimation, and repeatable holds across a dense grid. It is the choice for PRS competitors and technical long-range shooters who read and apply corrections methodically. The VHR (Variable Hunter Reticle) is a streamlined reticle with bold guides, intuitive holdover points, and a floating center for rapid target acquisition. It is optimized for hunters and dynamic shooters where speed of acquisition and a clean sight picture matter more than a full precision grid. Both reticles are available in this series in MOA and MRAD turret options.
