ARKEN SH4J-6241VPR VPR 6-24X FFP 34MM MRAD - SHIPS FROM SPORTS SOUTH
ARKEN OPTICS SH-4J 6-24x50 FFP RIFLE SCOPE — VPR ILLUMINATED / MRAD TURRETS / 34mm
The Arken Optics SH-4J 6-24x50 FFP VPR MRAD (SH4J-6241VPR) is the pure MIL/MIL configuration of the SH-4J VPR series: a first focal plane Variable Precision Reticle paired with MRAD-graduated turrets clicking at 0.1 MIL per click. The VPR reticle subtensions and the turret inputs share the same unit — there is no conversion required. Read a correction in MIL from the reticle grid and dial that same number directly: a 3.2 MIL correction is 32 clicks, read and applied in the same unit system without multiplication or rounding to a different increment.
The SH-4J platform brings Japanese ED glass standard, 34mm tube, 36.6 oz, and 32 MIL / 108 MOA of total elevation travel with an AZS zero stop. The VPR is a precision grid optimized for ranging, wind estimation, and methodical target engagement at extended distances. Red center illumination is provided for low-light aiming, and the sunshade is included for use in direct or oblique sunlight. At $329.99, the SH4J-6241VPR offers the SH-4J’s upgraded platform in the most natural pairing for precision rifle shooters who work in MIL throughout their entire workflow.
The Variable Precision Reticle is a first focal plane MIL grid with subtension marks for ranging, wind estimation, and target leads. In FFP, the VPR subtensions are accurate at every magnification from 6x through 24x. A target that spans 2 MIL at 6x still spans 2 MIL at 24x; no magnification-specific mental adjustments required. This is the defining advantage of FFP for precision work at variable power.
With MRAD turrets, every input from the VPR reticle goes directly onto the turret: spot a 2.5 MIL correction, dial 25 clicks. No multiplication by 3.44, no rounding to the nearest MOA click, no mental unit switching between the reticle and the turret. For competitive precision rifle shooting and methodical long-range hunting, this eliminates a systematic source of dialing error under field conditions.
The SH-4J’s 34mm tube delivers 32 MIL of total elevation adjustment — 320 clicks at 0.1 MIL each, across 4 full revolutions of 80 clicks per revolution. The AZS zero stop anchors return to zero: dial up from zero into elevation, use the optic at distance, then rotate back to the AZS stop. The stop returns the turret to zero without counting clicks back down.
The SH-4J upgrade from the base SH-4 includes Japanese Extra-Low Dispersion glass as standard. ED glass reduces chromatic aberration — the color fringing at high contrast edges that reduces resolution at high magnification and in low light. At 24x on a 50mm objective, the ED glass allows the SH-4J to resolve the fine VPR grid marks with clarity that supports confident ranging and correction reading at distance.

The SH-4J 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 scopes where clockwise is up. The AZS zero stop is reached by rotating clockwise back to the stop after dialing up corrections.
The SH-4J features an exposed, adjustable windage turret with 10 MIL / 34 MOA of total travel. Unlike the EP-L4 series’ capped windage design, the SH-4J windage is accessible without removing a cap. Most precision shooters zero windage at the range and use the VPR’s horizontal subtensions for in-field wind holds rather than adjusting the windage turret between shots.
The sunshade threads onto the 50mm objective bell to reduce glare in direct or oblique sunlight. Attach for improved contrast and resolution when shooting into the sun or across open terrain in harsh light. Detach when not needed; no effect on zero or adjustments.
Frequently Asked Questions
Why choose the MRAD variant over the MOA variant for the VPR reticle?
The VPR is a MIL-based precision reticle. Its subtensions — the hash marks and dots used for ranging and corrections — are calibrated in MIL. When the turrets also click in MIL (this scope, SH4J-6241VPR), every correction from the reticle reads directly onto the turret without conversion: spot a 2.3 MIL drop, dial 23 clicks. With the MOA turret variant (SH4J-6240VPR), a 2.3 MIL correction requires multiplying by 3.44 to get 7.9 MOA before dialing — an additional mental step that introduces rounding decisions under field conditions. For VPR users, the MRAD variant is the natural pairing. The MOA variant suits shooters who already have dope cards or ballistic data in MOA and want to add the VPR’s precision grid without converting their existing data.
What is the VPR reticle designed for?
The Variable Precision Reticle is a first focal plane MIL grid optimized for methodical precision engagement. Its primary applications are: (1) ranging using the MIL-dot method (target size in meters or yards divided by apparent MIL span, multiplied by 1000 for meters or a conversion constant for yards); (2) wind estimation by reading apparent drift against the reticle subtensions; (3) repeatable holdovers at known distances using the MIL grid as a reference; and (4) target leads for moving targets. It is used in competitive precision rifle disciplines and field applications where systematic reading of corrections is more important than sight picture cleanliness. For hunting scenarios where speed of acquisition and a clean sight picture take priority, the VHR reticle (available in SH4J-6240VHR or SH4J-6241VHR) is the alternative.
Does the SH-4J have a capped or exposed windage turret?
The SH-4J has an exposed, adjustable windage turret with 10 MIL / 34 MOA of total travel. The EP-L4 series uses a capped set-and-forget windage design; the SH-4J’s windage is accessible without a cap. Most precision shooters zero windage at the bench and use the VPR’s horizontal grid for wind corrections in the field rather than running the windage turret, reserving turret adjustments for known sustained crosswind conditions or positional offsets at the shooting position.
What rings fit the SH-4J?
The SH4J-6241VPR requires 34mm scope rings or a 34mm one-piece mount. Standard 30mm rings will not fit. For precision rifle applications, a 20 MOA canted Picatinny rail is a common pairing: it shifts the zero point lower in the adjustment range so more of the 32 MIL elevation travel is available above zero for dialing to distance. At 14.1 inches and 50mm objective, select ring height to ensure barrel clearance appropriate to your rifle’s receiver and barrel profile.
Is the battery included?
No. The SH-4J 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 precision scope without the battery in any light condition where the reticle is visible against the target.
