Initial Set Up
• Reticle Focal Plane (Second Focal Plane vs First Focal Plane)
All riflescope reticles can be termed either first focal plane (FFP)or second focal plane(SFP),with respect to the reticle's internal location within the erector system. An SFP reticle is visually consistent in size and weight across the magnification range; however the subtension values are only accurate on one magnification, typically the highest.In contrast,an FFP reticle will scale with magnification, and their subtensions used for ranging, holdovers, and wind corrections will remain constant. The reticle size will appear larger at higher magnifications, and smaller at low magnification.
• First Focal Plane Reticle
These Cuinfi 5-30x56 Rifle scopes feature a FFP reticle. FFP reticles are located within the rifle scope near the Wind age and elevation turrets.This style of reticle will appear to grow and shrink as you change the magnification.
• Ocular Focus -Fast Focus Eyepiece
The ocular focus is typically a onetime adjustment used to focus the reticle for maximum sharpness. This adjustment is slightly different for every shooter.A clearly focused reticle is a critical component for accurate shooting. When setting up a riflescope, this should be the first adjustment you make and should only need to be changed from user to user, or if your eyesight changes over time.
• Ocular Focus-Fast Focus Eyepiece Adjustment
The Magnification Adjustment Ring is used to change the riflescope's "power." The Cuinfi 1-6x24 rifles copes are variable powered optics with a 1x-6x optical design. To adjust your optic's magnification, rotate the Magnification Adjustment Ring clockwise, or counterclockwise, to increase or decrease the magnification to your desired level.
• Adjusting the Reticle Focus to your Eye
1. Turn the Magnification Adjustment Ring to the highest power.Looking through the optic, turn the Fast-Focus Eyepiece counterclockwise until the reticle is slightly blurry.
2. While looking at a white wall or a clear blue sky, taking short glances through the optic, turn the Fast-Focus Eyepiece clockwise until the reticle is clear and crisp as soon as you look through the optic. This may take several attempts.
Note: You do not want your eye to focus to the reticle,rather you want the reticle in focus to your eye instantly when looking through heoptic.Looking away and letting your eyes refocus is important ingetting the Fast-Focus Eyepiece set correctly.
Once this adjustment is complete, it will not be necessary to refocus every time you use the riflescope. However, because your eyesight may change over time,you should recheck this adjustment periodically.
• Parallax
Parallax results when the target image is not on the same optical plane as the reticle within the riflescope.This can cause an apparent movement of the reticle in relation to the target if the shooter's eye is off-axis behind the optic.
• Adjustable Parallax
The Cuinfi® 5-25x56 riflescopes come equipped with a Parallax Adjustment Knob located on thelefth and side of the turret housing. When the parallax is properly adjusted, the shooter should experience no parallax error.
Dial the Parallax Adjustment Knob until the target image isas sharp as possible. The yardage numbers on the knob should be used as general reference points only. Check for parallax error by moving your head up, down, left, and right without influencing the gun. The parallax is correct if there is no apparent shift between the reticle and the target image. If you notice any shift, adjust the Parallax Adjustment Knob slightly until all shift is eliminated.
Note: If the reticle and the image are not both simultaneously in focus, readjust your Fast-Focus Eyepiece.
• Magnification Adjustment
The Magnification Adjustment Ring is used to change the rifle scope's "power."The Cuinfi® 5-30x56 riflescopes are variable powered optics with a 1x optical design. To adjust your optic's magnification, rotate the Magnification Adjustment Ring clockwise,or counterclockwise,to increase or decrease the magnification to your desired level.
TURRETS
The Cuinfi® 5-30x56 riflescope is offered in Milliradian (MIL).
Note: The top of both the windage and elevation turret will state what unit the riflescope is laid out in.
• Milliradian (MIL)Adjustment
MIL, which is short for Milliradian and another unit of angular measurement, is defined as 1/1000th of a radian (6.2832 radians in a circle)and 1 MIL equals to 3.438 MOA and 3.6 inches at 100 yards, 7.2 inches at 200 yards, and to 36 inches at 1000 yards. 1/10 MIL per click takes 10 clicks to move point of impact 3.6 inches at 100 yards. Knowing the click value and the number of clicks needed for different distance is critical to dial in elevation and wind age adjustments based on the rifle ballistics and wind velocity.
• Elevation and Windage Turrets
Use turrets to adjust the bullet's point of impact. The Cuinfi®5-30x56 SFIRY riflescope uses a 1/10 MIL turret adjustment on both the Windage and Elevation Turrets. Each click will move the bullet's point of impact roughly. 36"at 100 yards. The turret on the top of the riflescope is the Elevation Turret, which is used to adjust the bullet's point of impact up and down. The turret on the right-hand side of the riflescope is the Windage Turret and is used to adjust the bullet's point of impact left and right.
• Exposed Turrets
The Cuinfi® 5-30x56 riflescopes come equipped with exposed turrets.This allows the shooter to quickly dial in their elevation and windage adjustments.
• To Make Turret Adjustments:
1. Pull up on the turret so that it is no longer in the locked position.
2. Following the direction arrows,turn the dial in the direction you wish the bullet's point of impact to change.(If you hit high,dial down.If you hit low,dial up.If you hit right, dial left. If you hit left, dial right.)
3. When finished adjusting,push down to lock the turret in place.
• Illumination
The Cuinfi riflescopes use a variable intensity illuminated reticle to aid in low-light performance.
To Turn Illumination On
To activate the illumination, rotate the lllumination Control Knob in a clockwise direction.
To Adjust Illumination Brightness
Once the illumination is on,continue to rotate the lllumination Control Knob clockwise to cycle through 6 levels of brightness. To decrease the brightness,rotate the lllumination Control Knob counterclockwise.
To Turn Illumination Off
To turn off the illumination,rotate the lllumination Control Knob all the way in either direction to dot.
Note: When the illumination is off,the reticle will appear black.
• Battery Installation/Replacement
To install/change the battery, unscrew the lllumination Control Knob's cap and install a new CR2032 battery with the positive side (+facing out.
• Replacing the Battery
1. Hold the Parallax Adjustment Knob and Unscrew the lllumination Control Knob cap by spinning counter-clockwise.
2. Remove the CR2032 battery.
3. Replace with a new CR2032 battery with the positive side (+facing out
4. Reinstall the battery cap by spinning clockwise until tight.
• Riflescope Mounting
To get the best performance from your riflescope,proper mounting is essential.Although not difficult,the correct steps must be followed.If you are unsure of your abilities,use the services of a qualified gunsmith.
• Rings and Bases
The Cuinfi® 5-30x56 riflescope feature a 34mm main tube. Be sure to select a base and matching rings appropriate for your riflescope's mount according to manufacturer's instructions.
Tip: Selecting the proper ring height to provide appropriate clearance between the riflescope and any part of the rifle is paramount.The proper height will also allow for a comfortable head position and aid in establishing a solid and consistent shooting position.A ring's height will not have an adverse effect on accuracy and overall range or performance.
• Eye Relief and Reticle Adjustment
After installing the bottom ring halves on the mounting base,place the riflescope on the bottom ring halves and loosely install the upper ring halves.Before tightening the riflescope ring screws,adjust for maximum eye relief to avoid injury.
1. Set the riflescope to its highest magnification.
2. Move the riflescope fore and aft in the rings until you achieve a full,unobstructed sight picture.
3. Without disturbing the fore-aft placement,rotate the riflescope until the reticle is level. Use a leveling tool(s) such as feeler gauges or bubble levels and a plumb bob to aid in this process.
4. After leveling the reticle,tighten and torque the ring screws down per manufacturer's instructions. Use caution and do not over-tighten ring screws.
