ARKEN SH4GII-4160VPR VPR 4-16X FFP 34MM MOA - SHIPS FROM SPORTS SOUTH
ARKEN OPTICS SH-4 GENII 4-16x50 FFP RIFLE SCOPE — VPR ILLUMINATED / MOA TURRETS / 34mm
The Arken Optics SH-4 GENII 4-16x50 FFP VPR MOA (SH4GII-4160VPR) pairs the SH-4 GENII platform with the Variable Precision Reticle (VPR) and MOA-graduated turrets. The VPR is a first focal plane MIL grid for precise ranging, holdovers, and wind calls — a full-featured precision reticle designed for PRS competitors and technical long-range shooters. The turrets on this variant click in 1/4 MOA increments at 20 MOA per revolution. This is a cross-unit configuration: the VPR subtensions read in MIL, the turrets dial in MOA. When reading a correction from the reticle and dialing it, multiply the MIL value by 3.44 to convert to MOA clicks. Shooters who prefer to work entirely in one unit can consider the MRAD companion (SH4GII-4161VPR), which delivers a native MIL/MIL workflow with 0.1 MIL per click.
The SH-4 GENII delivers 36 MIL of total elevation travel and 14 MIL of windage travel in a 13.4-inch, 35.6 oz package. The AZS zero stop provides a mechanical anchor for return to zero, and the sunshade is included. This configuration suits shooters who use the VPR for precision aiming, ranging, and spotting in MIL while keeping turret inputs in MOA — either because existing ballistic data is already in MOA or because current data systems or dope cards are MOA-based.
The Variable Precision Reticle is a first focal plane MIL grid with subtension marks for ranging, wind estimation, and target leads. Subtensions are accurate at every magnification from 4x through 16x. A target sized to 3 MIL at 4x still measures 3 MIL at 16x. The FFP construction eliminates the need to apply a magnification correction to your subtension readings — the VPR is always live regardless of where the power ring is set.
This scope’s turrets click in 1/4 MOA increments: 20 MOA per full revolution. At 100 yards, each click moves the point of impact approximately 0.26 inches. For ballistic data already in MOA — from an existing dope card, a ballistic app set to MOA output, or prior data from an MOA-click scope — dial the output directly to the turret without any conversion.
When the VPR is used to read a correction directly in MIL and those clicks need to be dialed on the MOA turret, multiply the MIL value by 3.44. Common examples: 1 MIL = 3.44 MOA (14 clicks); 2 MIL = 6.88 MOA (28 clicks); 3 MIL = 10.3 MOA (41 clicks); 5 MIL = 17.2 MOA (69 clicks). A ballistic app that displays holds in MIL and dials in MOA handles this automatically.
The VPR MOA setup is practical when the VPR is used as a precise aiming and spotting grid — reading holds and wind off the subtensions in MIL — while all dialing is driven by a ballistic app or existing dope card with MOA outputs. It suits shooters transitioning from MOA-click platforms who want to add the VPR’s precision grid without overhauling existing data. For new shooters building from scratch, the MIL/MIL companion (SH4GII-4161VPR) is typically simpler to manage.

The SH-4 GENII elevation turret increases elevation with counter-clockwise rotation, consistent with the Arken EP and SH series. Confirm direction during your first zeroing session — this is opposite to many common production scopes where clockwise is up. The AZS zero stop is reached by rotating clockwise back to the stop after dialing up.
When reading a VPR correction in MIL and dialing MOA turrets: MIL × 3.44 = MOA. Common conversions: 1 MIL = 3.44 MOA (14 clicks); 2 MIL = 6.88 MOA (28 clicks); 3 MIL = 10.3 MOA (41 clicks); 5 MIL = 17.2 MOA (69 clicks). A ballistic app configured to display both MIL holds and MOA dials can handle this in the field automatically.
The sunshade threads onto the 50mm objective bell to reduce glare in direct or oblique sunlight. Useful during dawn and dusk or when shooting across open terrain into low-angle light. Attach or remove without affecting zero or turret settings.
Frequently Asked Questions
This scope has a MIL reticle but MOA turrets — is that an issue?
It is a cross-unit configuration, which requires a conversion step when reading a correction directly from the VPR reticle and dialing it on the MOA turrets: multiply the MIL value by 3.44 to get MOA, then dial. Whether this is a practical issue depends on your workflow. If you drive turret inputs from a ballistic app or existing dope card already in MOA, this scope works naturally — your data tells you how many MOA to dial, and the VPR gives you a precision grid for holds, ranging, and wind reads in the field. If you want a single consistent unit from reticle read to turret dial, the SH4GII-4161VPR (MRAD turrets) eliminates the conversion entirely.
What is the difference between the VPR and VHR reticles?
The VPR (Variable Precision Reticle) is a full MIL grid designed for technical precision work: ranging using MIL subtension measurements, precise wind estimation, and repeatable holdovers across a dense reference grid. It is optimized for PRS competitors and long-range shooters who read and apply corrections methodically. The VHR (Variable Hunter Reticle) is a streamlined design with bold holdover guides, intuitive reference points, and a floating center for rapid target acquisition — optimized for hunters and dynamic shooters who prioritize speed and clean sight picture over technical grid density. Both reticles are available in this series in MOA and MRAD turret configurations at the same price.
What rings fit the SH-4 GENII 4-16x50?
The SH4GII-4160VPR requires 34mm scope rings or a 34mm one-piece mount. Standard 30mm rings are not compatible. At 13.4 inches and 50mm objective, select ring height based on your barrel clearance requirements. A 20 MOA canted Picatinny rail is a practical pairing for precision applications, shifting the zero point lower in the adjustment range so more of the elevation travel is accessible 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.
