Product Usage Instructions

Reticle Focus Adjustment

To adjust reticle focus, follow these steps:

1. Rotate the Reticle Focus Ring while looking at an unobstructed background.
2. Adjust in short bursts and look away between each adjustment.
3. Ensure the reticle is sharp and stable without appearing to move with small head adjustments.

Parallax Adjustment

To eliminate parallax, rotate the Parallax Adjustment Turret until all reticle movement within the eye box is eliminated.

Variable Power Adjustment

To adjust magnification, rotate the Magnification Ring to the desired power level indicated on the ocular housing.

Arken Zero Stop (AZS) & Turret Alignment

The AZS allows a quick return to zero. Follow these steps:

1. Loosen the AZS Set Screw with a 2mm Allen wrench on the elevation turret and raise the AZS Zero Stop.
2. Set the turret to zero by aligning the indicators and tightening the retaining screws.
3. Adjust the AZS by rotating it up for 2 clicks and then set it. Rotate back to zero for a firm stop.

Windage Adjustment

To adjust windage, follow these steps:

1. Unscrew Windage cap and hold the turret in place.
2. Unscrew the Toolless Windage Retention System to zero.

FAQ

• Q : How do I determine if my scope features MIL or MOA scale?
• A : Reference the top of the elevation turret. The scale indicated there will specify MIL or MOA.

The Subtension Scale: MIL or MOA

Depending on which version you have purchased, your SH-4 rifle scope will feature elevation/windage adjustments and reticles scaled in either MOA or MRAD (MIL). If you are unsure of which scale you have, reference the top of the elevation turret. Both units of arc scales are effective at ranging and/or adjusting for bullet trajectory. For best results, the user must understand either system being employed. We recommend understanding both. MRAD (Milliradian): 1/1000th of 1 radian of arc

• 1 MIL = 3.438 MOA
• 1 MIL = 3.599 inches @ 100 yards
• 1/10 MIL = 0.359 inches @ 100 yards

• MOA (Minute of Angle): 1//60th of 1 degree of arc
• 1 MOA = 1.047 inches @ 100 yards
• ¼ MOA = 0.261 @ 100 yards.

Reticle Focus Adjustment

To adjust reticle focus, rotate the Reticle Focus Ring while looking at an unobstructed background. The eye will continually refocus, so this should be done in short bursts. Look away between each adjustment. The reticle should be sharp and should not appear to move with small head adjustments. Once properly set, the eye should not have to work to get the reticle in focus

Parallax Adjustment
To eliminate parallax, rotate the Parallax Adjustment Turret. Proper adjustment will eliminate all reticle movement within the eye box.
Variable Power Adjustment
To obtain the desired magnification, rotate the Magnification Ring so that the indicator on the Ring corresponds with the magnification power level on the ocular housing.

Arken Zero Stop (AZS) & Turret Alignment
The Arken Zero Stop (AZS) allows the shooter to quickly and consistently return the elevation turret back to the sight in the distance (or zero). Please use the 2mm Allen wrench to loosen the AZS Set Screw on the elevation turret and raise the AZS Zero Stop.

Elevation

1. ‘Slip’ Elevation turret:
   Hold the turret in place to ensure the turret does not move during this process. Please use the 2mm allen wrench to loosen the THREE turret cap retaining screws on the SIDE of the turret. This will allow the turret to spin freely without rotating the internal components of the turret.

2. Set Turret to Zero “0” :
   Rotate the turret cap to align the “0” indicator mark of the turret cap with the indicator mark on the scope tube. Carefully, tighten the THREE retaining screws on the SIDE of the elevation turret cap.

3. Set the AZS (Arken Zero Stop)
   Rotate the turret UP 2 clicks. Gently, turn the AZS located on the TOP of the elevation turret clockwise to lower until you feel the AZS bottom out. Then, loosen the AZS a quarter turn to alleviate any tension. Finally, tighten the AZS Set Screw against the AZS.

4. Rotate the turret back to Zero “0”.
   AZS IS SET. You should have a firm stop that allows you to consistently return to zero.

Windage

1. ‘Slip’ Windage Turret:
   Unscrew the Windage cap.

2. Unscrew Toolless Windage Retention System: Hold the turret in place to ensure the turret does not move during this process.

3. Set Turret to Zero “0”:
   Slide off the numbered cap. Rotate/align the “0” indicator mark of the numbered cap with the indicator mark on the scope tube and slide back on the main body.

4. Screw in Toolless Windage Retention System finger tight: Hold the turret in place to ensure the turret does not move during this process.

5. Replace the Windage cap.
