hunters the ability to match elevation adjustment to their favorite cartridge and bullet, making pinpoint accuracy easier to achieve.
Send us your cartridge information online and we’ll provide a custom elevation knob that matches your favorite load. PLUS, we’ll provide a customized Wind Map that shows, in MOA, a 10 MPH wind hold-off value for your cartridge at 100-yard increments. The simple­to-use C4 Wind MOA Reticle works seamlessly with your customized Wind Map, featuring MOA tick marks that extend out to 10 MOA in each direction, making it quick and easy to calculate hold-off for wind.
Let the C4 Plus riflescope take you one step closer to perfection!
The C4 Plus custom knobs eliminate the guesswork for holdover. Just dial in the known distance and use the MOA Wind Map to determine the hold-off for a 10 MPH wind. In the example above, at 400 yards you simply hold 2.9 tick marks into the wind for pinpoint accuracy.
Note: It is important that you provide Burris with the most accurate load and environmental information as possible. Burris warrants that each Custom Clicker and Wind Map will be calibrated mathematically correct for the data you provide. Burris is not responsible for any inaccuracy to the actual trajectory realized by velocity, ballistic coefficient, or environmental variances in field conditions compared to the data provided by you or an ammo/bullet manufacturer for preparing the Custom Clicker and Wind Map.

How to Receive Your Free Custom Clicker
and Wind Map
1. Determine precisely the load you will shoot - either a factory load or handload.
2. If choosing a factory load and if you have access to a chronograph, measure the actual velocity of the factory load. If you do not have access to a chronograph and/or do not provide a muzzle velocity to us, we will use the advertised velocity for your factory load.
3. If choosing a handload, either obtain the actual muzzle velocity or estimate the muzzle velocity based on your reloading manual(s).
4. Make note of the scope serial number on the bottom portion of the adjustment turret.
5. Log on to www.BurrisOptics.com, enter the Ballistic Services section and choose the C4 Clickers option.
6. Follow the prompts for providing Burris with all the necessary information for Burris to produce a perfected Custom Clicker and Wind map for you. Your first Custom Clicker and Wind map is FREE with the purchase of your C4 Plus Riflescope.

Installing Your Custom Clicker Elevation Knob
1. It is best to sight-in your riflescope prior to installing your Custom Clicker.
2. Being careful not to rotate the elevation knob, loosen the three set screws that hold the elevation knob in place. Lift the knob up and off of the scope.
3. Place the Custom Clicker onto your scope, aligning your sight-in yardage number to the reference mark on the scope.
4. Apply a small amount of downward pressure onto the Custom Clicker and then evenly tighten the three set screws. Turn your Custom Clicker about a half-turn counter-clockwise and then clockwise back to your sight-in distance to get a feel for the amount of resistance to turn the clicker. If you desire more or less resistance, loosen the three set screws and apply more or less downward pressure onto the Custom Clicker; retighten the set screws. Retest and reset the resistance until satisfied.

How to Use Your C4 Plus Riflescope
Calculating Holdover/Hold-Off
The C4 Plus Custom Clicker ensures that elevation adjustment perfectly matches the ammunition you are shooting, and when used properly eliminates the need to calculate holdover. Determining an accurate distance to your target is key, and Burris recommends using a rangefinder in the field for optimum accuracy. Once the distance to your target is confirmed, turn the dial on your Custom Clicker elevation knob to match that distance. For example, if your target is 250 yards away, turn your Custom Clicker until 250 is aligned with the reference mark on your scope. Since the scope is calibrated to your cartridge, dialing the yardage to your target allows you to use the center point of the reticle crosshairs as your aiming point – no holdover or under is needed.
To correctly determine hold-off for wind, first determine as best as you can the wind speed at your target. Refer to the customized Wind Map provided by Burris that shows, in MOA, the accurate hold-off value for a 10 MPH wind at a specific 100-yard increment distance.
Using this Wind Map as an example, if your target is 200 yards away and the wind is blowing 10 MPH, you will hold-off 1.3 reticle tick marks into the wind. The wind is blowing 20 MPH? Double the value and hold-off 2.6 reticle tick marks into the wind. It’s blowing only 5 MPH? Cut the value in half and hold-off .65 tick marks into the wind.

Installing the Wind Map
Each Wind Map is shaped such that it can be easily installed and used in multiple positions such as the Objective Bell Taper, the Eyepiece, or the Riflestock.
Our recommendation is to install the WindMap on the Objective Bell taper approximately 10° – 20° left or right of the top center depending on whether you shoot right- or left-handed. This position allows you to see the Wind Map with your “off-eye” while viewing through the scope. It also provides for a somewhat protected position against scratching.
Locate exactly where you want to place the Wind Map and clean the surface of any dust and oils with soapy water or rubbing alcohol. Peel off the adhesive covering on the back of the Wind Map and carefully install at your desired location.
Eyepiece Focusing
The eyepiece can be focused so that the reticle appears sharp and black to your eyes. Follow this procedure to adjust the focus:
1. Point the scope at the sky or a plain wall and take a quick glance through the scope. If the reticle appears sharp and black, no further adjustment is necessary.
2. If the reticle does not appear sharp and black, take
quick glances through the scope while rotating the focus ring until the reticle pattern is sharp and clear.
NOTE: Do not look through the eyepiece as you turn the focus ring. Your eyes will adjust to the out-of-focus condition.

Mounting the Scope
C4 Plus riflescopes are available with either 1” or 30mm body tubes; please be sure you choose the correct ring sizes for your model as indicated by the end label sticker on your riflescope box . We recom­mend using high-quality rings and bases, like Burris Zee Rings or Signature Rings. Quality components ensure that your scope will remain safely and securely mounted, and will provide the maximum accuracy. Use care when mounting your scope as damage can occur
Care & Maintenance
The C4 Plus riflescope is fully waterproof and fogproof. In the event that the lenses are subjected to dust, dirt or mud, follow these steps to clean and protect the lens surface. Failure to remove grit before final cleaning is sure to damage lens coatings.
Coarse dirt/debris must be removed from the lens surface. The most convenient way to clean a lens surface is to use a Lens Pen. Position the scope so particles will fall away from the lens, and then use the Lens Pen or soft brush to gently whisk away the debris, while blowing on the lens to dislodge the particles. For heavy dirt, like dried mud, use a spray of clean water or lens cleaning fluid to remove the dirt.
Your Burris riflescope will provide reliable performance given reasonable care and treatment. All moving assemblies are permanently lubricated. Only occasional cleaning of the outside of the scope and the exterior lenses is required. Never disassemble your scope. If you have any other problems with your riflescope, please return it to the Burris factory for repair.
