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.
• Second Focal Plane Reticle
These Cuinfi® 3-9x40 riflescope features a second focal plane(SFP)reticle. SFP reticles are located within the riflescope near the magnification ring. This style of reticle will appear consistent throughout the entire magnification range.
Note: The Cuinfi® 3-9x40 riflescope reticle are calibrated at the highest magnification.For the hashmark's value to be true,you need to be on the highest magnification.
• Parallax Adjustment
The Cuinfi® 3-9x40 riflescope is non-adjustable for parallax correction and is set from the factory to be parallax-free at 100 yards(90 meters).When shooting at distances other than 100 yards, using good consistent shooting form and cheek weld will prevent most problems with parallax.
• Magnification Adjustment
The Magnification Adjustment Ring is used to change the riflescope's "power." The Cuinfi®i 3-9x40 riflescopes are variable powered optics with a 3x-9x 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® 3-9x40 riflescope is offered in Minute of Angle (MOA).
Note:The top of both the windage and elevation turret will state what unit the riflescope is laid out in.
• Minute of Angle (MOA)Adjustment
Minute of Angle is an angular unit of measurement commonly found in riflescopes. It is used to measure bullet drop, wind holdovers, and for measuring targets. Both the reticle and turrets will be laid out in specific MOA values. 1 MOA equates to 1.047"at 100 yards, 2.09"at 200 yards, 3.14"at 300 yards,etc.Being an angular unit of measurement, the value of 1 MOA will increase/decrease proportionally as you increase / decrease the distance you are shooting. For this reason, think about all of your adjustments in MOA, rather than a linear unit such as inches. If your turret, reticle, and drop chart are all laid out in MOA, adjusting your riflescope for bullet drop or Wind age corrections is extremely easy.
• 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.
• Capped Turrets
The Cuinfi® 3-9x40 riflescopes come equipped with Capped Turrets.This protects the turrets from accidental adjustment while out in the field,in transit,or in storage. You will need to remove the caps prior to making any adjustments on the turrets.
Note:The riflescope is still waterproof with the caps removed.
• To Make Turret Adjustments:
1. Remove the turret caps by spinning them counterclockwise.
2. Following the directional arrows,turn the dials 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,replace the turret caps.
Note: The reticle will move in the opposite direction of the turret dials. When you dial up,the reticle will move down, forcing you to aim higher, changing your point of impact upward.
• Riflescope Mounting
To get the best performance from your Cuinfi® 3-9x40 riflescope,proper mounting is essential.Although not difficult,the correct steps must be followed.If you are unsure of your abilities,it would be best to use the services of a qualified gunsmith.
• Rings and Bases
The Cuinfi® 3-9x40 riflescope feature a 1 inch 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.

The Dawn multi-coating is a specialized spectral treatment. While standard coatings reduce general reflection, our Dawn technology is tuned to enhance contrast in low-light conditions (dawn and dusk). This allows more usable light to reach the eye when the sun is low on the horizon, extending your effective operating time in the field.
Yes. This scope is built with a reinforced erector system and aircraft-grade aluminum. It is tested to withstand the heavy, sharp recoil of magnum calibers. The internal components are shock-mounted to ensure that the reticle and internal glass elements remain secure even after hundreds of high-energy shots.
This specific model features a fixed parallax set at 100 yards. This is intentional for a hunting-focused optic, as it simplifies the user experience by removing one more dial to manage in high-stress situations. At the 3-9x magnification range, the parallax error is negligible for standard hunting distances.
During assembly, the atmospheric air inside the tube is replaced with dry nitrogen gas. This gas contains zero moisture. When the scope moves from a warm environment to a cold one, there is no moisture inside to condense on the inner lens surfaces. This ensures your view remains crystal clear regardless of the weather.
The SFP reticle remains the same size visually regardless of the zoom level. While this means the hash marks (if using a Mil-Dot) only represent specific measurements at one magnification (usually 9x), it provides a very clear and fine aiming point that does not grow and "cover up" the target at high power, which is preferred by many traditional hunters.
