Mounting Tips and Tricks

When it comes to securing your LH-6 to your firearm, getting it right the first time is crucial for accurate shooting. Here are some tips and tricks to ensure your scope is mounted correctly on your rifle.

We recommend using ARKEN OPTICS USA Mounts: Select mounts designed to complement ARKEN scopes, ensuring a seamless and stable connection between your scope and rifle. Clean and Degrease: Before mounting, clean the mounting surfaces on both the rifle and the scope. Remove any old oil or residue to ensure a solid connection. Torque Wrench is Your Friend: Use a torque wrench to tighten screws to our specifications. This ensures consistent pressure and prevents over-tightening. Properly Level the Scope: A leveling tool helps ensure the scope is perfectly aligned with the rifle. This step is often overlooked but is crucial for accuracy. Eye Relief: Position the scope to achieve the proper eye relief for your shooting style. This is the distance between your eye and the scope.

Bore Sighting: Before finalizing the mounting, perform a bore sight. This gets your scope on paper before you head to the range for fine-tuning. Recheck and Test: After mounting, recheck all screws for tightness. Take your rifle to the range and test for accuracy. Consider Recoil: If you’re mounting on a high-recoil rifle, ensure there’s enough eye relief to prevent scope bite. Apply Thread Locker Sparingly: Use a small amount of thread locker on screws and bolts to prevent them from loosening due to recoil vibrations. Consult a Professional: If you’re unsure, seek advice from a professional gunsmith. They can ensure your scope is mounted perfectly.

A well-mounted scope can make a world of difference in your shooting experience. Following these tips will help you achieve the best results with your scope.

Focusing the LH-6 / Setting the Diopter

1. Begin with the magnification ring set at 1X. 2. Keep both eyes open and ensure proper eye relief, ensuring there’s no shadowing around the edges of your view. 3. Gradually rotate the ocular ring to align the peripheral view with the internal view seen through the optic. 4. Continue adjusting until you achieve a flat, distortion-free image and a crisp, clear reticle. 5. Ensure there’s no deviation in the image from the peripheral to the internal view — this is the hallmark of a true 1X magnification setting. This calibration process ensures that your LH-6 delivers optimal performance, providing you with a genuine 1X magnification experience.

Variable Power Adjustment

1. Begin with the magnification ring set at 1X. 2. Rotate the magnification ring until the indicator aligns with the desired power level marked on the ocular housing. 3. Gradually increase the magnification for a closer view of your target. The LH-6 scope offers a versatile range from 1X for quick acquisition to 6X for honing in on distant details.

ARKEN LH-6 Throw Lever

1. Begin by locating the raised tab on the magnification ring of your LH-6 scope. 2. Take the provided Throw Lever and screw it into the threaded hole in a clockwise direction. Ensure it is snug but avoid over tightening, as this can lead to thread or slot damage. 3. With the Throw Lever in place, you now have an extension for your magnification adjustments. This enhancement allows for rapid and precise changes.

Windage and Elevation Adjustments

Making precise adjustments to windage (horizontal) and elevation (vertical) settings on your LH-6 scope is crucial for achieving accurate shots. Follow these steps to master this process: 1. Locate the Turrets: Identify the windage and elevation turrets on the scope body. Looking directly at the eyepiece, the windage turret is located on the right side, and the elevation turret is on top. The windage and elevation turrets are the only turrets that have caps on them that cover them completely. 2. Understand the Directional Movements: Windage: Turning the windage turret clockwise moves the point of impact to the left and counter clockwise moves it to the right. Elevation: Rotating the elevation turret clockwise lowers the point of impact and counter clockwise raises it. 3. Making Adjustments: Windage: Use the windage turret to move the point of impact horizontally, aligning it with your point of aim. Elevation: Utilize the elevation turret to adjust the point of impact vertically, aligning it with your point of aim. 4. Recording Changes: Keep track of the adjustments made. Scopes use Minute of Angle (MOA) or Milliradian (MRAD) measurements for precision. 5. Fine-Tuning: Fire additional shots, making minor adjustments as needed to achieve the desired point of impact. Remember, each click of the turret represents a specific angular measurement. Familiarize yourself with your scope’s specifications to interpret adjustments accurately.

Utilizing the LH-6 6X Magnification

1. Bore-Sighting Preparation: Begin by bore-sighting your rifle. This ensures that the initial shots are close to the point of aim. 2. Firing Initial Rounds: Fire a series of three to five rounds at the target. 3. Measure POA vs. POI: Determine the difference between the point of aim (POA) and the point of impact (POI). Use the reticle or a measuring device on the target. 4. Adjust Elevation and Windage: Using the adjustment turrets, make necessary changes to align the POA with the POI. 5. Confirmation Rounds: Fire an additional three to five rounds to verify the zero. Continue adjustments until the POA and POI coincide. Please note: Each click of the turret represents a specific angular measurement. Familiarize yourself with your scope’s specifications for accurate adjustments. Standard information required: Bullet weight, caliber, ballistic coefficient, muzzle velocity, and atmospherics. Zero to 50/200 Yards

Follow these steps to utilize the 6X magnification feature effectively: 1. Zeroing at 50/200 Yards: Begin by zeroing your rifle at a distance of 50 or 200 yards. 2. Utilize a Ballistic App: Employ a ballistic application to calculate the elevation adjustments needed for distances of 600 and 800 yards. Keep in mind the bullet’s Ballistic Coefficient (BC). Note: For bullets with a low BC, the true distance will be 600 yards. For those with a high BC, it will be 800 yards. Refer to the provided reference chart for guidance. 3. Adjust the Elevation: From the KLBOX center mass hold on the reticle, subtract the calculated MOA value for the respective distance (600 or 800 yards). Example: For 600 yards: Subtract -14.78 MOA For 800 yards: Subtract -26.12 MOA 4. Elevation Turret Adjustment: Based on the result obtained, make adjustments to your Elevation Turret: If the value is positive, **ADD** it to your Elevation Turret. If the value is negative, **SUBTRACT** it from your Elevation Turret.

Illuminated Reticle Adjustment Your LH-6 scope features a daylight-visible, externally adjustable illumination for enhanced visibility.

Here’s how to effectively manage it:

1. Locating the Illumination Turret: The illumination turret is conveniently positioned opposite the windage turret for easy access. 2. Battery Cap Placement: It’s important to note that the battery cap for the illumination turret is situated on top. However, rotating the battery cap will not affect the illumination settings. 3. Activating the Illuminated Reticle: To activate the illuminated reticle, simply rotate the external dial: **1 through 9** adjusts the intensity of the illumination. **0** represents the "off" setting. 4. Conserving Battery Life: When not in use, always ensure the scope is set to **0** to prevent unnecessary drainage of the CR2032 battery. 5 . Environmental Considerations: Keep in mind that lighting conditions and the environment can impact the optimal setting. In low light, excessive illumination may lead to unintended effects. The LH-6 uses a CR2032 battery, located within the illuminated reticle turret (opposite side of the windage turret). You’ll find the battery cap positioned atop this turret. To access, install, or replace the battery, rotate the cap counterclockwise. It will gradually come off, revealing the designated battery slot. Ensure that the positive side (+) of the battery is oriented towards the top. Replace the cap on top and turn it clockwise by hand to securely seal the battery. Be sure to tighten it appropriately, taking care not to cross- thread it. Use a comfortable level of hand strength for sealing. Battery Replacement

Setting ZERO:

1. Unscrew the LH-6 toolless retention center cap. Hold the outer body of the turret in place to ensure it doesn’t move during this process. Set the turret to "0": 2. Slide off the numbered cap. Rotate and align the "0" indicator mark of the numbered cap with the indicator mark on the scope tube. Slide the cap back onto the main body. Screw in the LH-6 toolless retention center cap. Take care not to cross-thread. 3.
