Barnett 4x32mm Crossbow Scope

Important Safety Information

WARNING: NEVER look at or view the sun through the scope, as permanent eye damage will result. Ensure the crossbow is unloaded and uncocked before making any adjustments to the scope, including installation, removal, or sighting-in. Only shoot a crossbow at an approved shooting range and strictly follow all safety instructions provided with your crossbow manual. Mount the scope far enough forward to avoid contact with your eye or face during shooting due to crossbow recoil. Do not attempt to disassemble or clean the scope internally, as this will void the warranty and render the scope unusable. Keep protective lens covers on when not in use. Clean external optical surfaces with the provided lens cloth or optical quality lens paper. Remove dirt or sand with gentle air pressure and a soft brush to avoid scratching. In salty environments, wipe the scope with a damp cloth, then a dry cloth. Wipe metal parts with a silicone cloth to protect against corrosion. Do not spray with silicone lubricant aerosol. Store the scope in a moisture-free environment, avoiding vehicle passenger compartments or trunks due to temperature fluctuations that can affect internal lubricants and sealants. Failure to follow these instructions may result in serious injury and/or property damage.

Adjusting the Ocular Lens

The ocular lens housing features a fast-focus thread for quick adjustment to achieve a sharp reticle for your eyesight. Set the focus in similar light conditions and at the approximate range you expect to use the scope. The reticle should appear sharp instantly when you look through the scope. It may take several attempts to achieve perfect focus.

Adjusting Eye Relief / Field of View

Achieve a clear, level crossbow scope sight picture or field of view by holding the crossbow in your normal shooting position. A full field of view should be visible without straining your head or neck. This may require moving the scope assembly forward or backward on the crossbow's picatinny rail.

1. Support the uncocked/unloaded crossbow on a sturdy surface and loosen the scope ring base cap screws using the provided 7/64" Allen wrench.
2. Raise the crossbow to a standard shooting position and look through the scope. Adjust the scope forward or backward until a clear, unobstructed field of view is visible without straining your head or neck. Ensure your eye is not too close to the scope assembly to prevent injury from recoil. If your eye is too close, use the ocular lens adjustment to focus and move your eye further from the lens.
3. Rotate the scope so the horizontal crosshair is parallel to the string and limbs. Retighten the top ring screws and verify the scope has not moved from its optimal position.
4. Check the scope assembly for tightness every few shots and readjust/retighten as needed.

Initially Zeroing the Scope

Ensure your crossbow manual is read in its entirety and you have a safe shooting location with a proper backstop. Backstops are crucial for stopping errant shots and protecting property and persons.

1. Place a target approved for crossbow use on the backstop at a measured distance of 10 yards (30 ft / 9.14m).
2. Following all safety precautions and warnings, aim the top (20-yard aim point) reticle at the center of the target and fire a shot. Note the arrow's point of impact (POI) on the target.
3. Remove the caps from the windage and elevation turrets. Make appropriate adjustments to the turrets to move the POI closer to the point of aim (POA).
4. Establish the direction(s) the bullseye was missed. For example, if the shot was high, rotate the elevation turret clockwise.

Note: At 10 yards, both windage and elevation turrets move the POA 1/20th of an inch per click. Therefore, 20 clicks will move the POI approximately one inch.

After achieving the bullseye at 10 yards, move back to 20 yards (60 feet / 18.2 m). Repeat the zeroing steps for 20 yards.

Note: At 20 yards, both windage and elevation turrets move the POA 1/10th of an inch per click. Therefore, 10 clicks will move the POI approximately one inch.

Point of Aim (POA) vs. Point of Impact (POI)

Point of Aim (POA): The spot on the target where the shooter aims.

Point of Impact (POI): Where the arrow actually strikes the target.

Once POA and POI are established, follow the steps above to sight in your scope.

Arrow Speeds & Reticle Aim Points

Your crossbow scope features defined reticle aiming points, each representing a specific distance to your target. Arrow speeds vary between crossbows, affecting the trajectory and thus the distance each aiming point represents. For faster crossbows (over 400 feet per second), arrows have flat trajectories, resulting in tight groups up to 40 yards. In such cases, the aiming points might correspond to 20, 30, 40, 50, 60, and 70 yards from top to bottom. The aiming points are not evenly spaced because arrow drop becomes more pronounced at longer distances. For crossbows with arrow speeds between 350-399 feet per second, aiming points might represent distances like 20, 35, 45, 60 yards, and so on. It is crucial to determine the exact target distance that correlates with each reticle aiming point for your specific crossbow's arrow speed through range practice.

Shooting Aiming Point Gaps

For targets at distances falling between two aiming points (e.g., 38 yards), you can aim at the gap between the corresponding aiming points (e.g., 30 and 40 yards), depending on your crossbow's speed. This is known as "shooting the aiming point gap." It is highly recommended to carry a laser range finder during hunting and shooting excursions to minimize guessing yardage distances and increase success.

Illuminated Reticle

The 4x32mm scope has six reticle aiming points that can be illuminated in red or green. The illumination on/off switch and brightness control rheostat are located on the side of the scope. The system is powered by a CR2032 3V coin-style battery, located under the screw-on battery cover. Ensure the positive (+) terminal faces up when replacing the battery. The reticle offers 5 intensity levels for both red and green illumination, suitable for low-light and bright conditions. Rotate the dial clockwise or counter-clockwise to turn on the illumination and select the color (red or green). Continue rotating to increase brightness. To turn off illumination, rotate the dial back to the "B" position indicated at the base of the dial.
