The Burris® C4 Plus™ (Cartridge CalibratedCustom Clicker – plus WindMap) system givesshooters and hunters the ability to matchelevation adjustment to their favorite cartridgeand bullet, making pinpoint accuracy easier toachieve.

Send us your cartridge information online andwe’ll provide a custom elevation knob thatmatches your favorite load. PLUS, we’ll provide acustomized WindMap that shows, in MOA, a 10MPH wind hold-off value for your cartridge at100-yard increments. The simple-to-use C4 WindMOA Reticle works seamlessly with yourcustomized WindMap, featuring MOA tick marksthat extend out to 10 MOA in each direction,making it quick and easy to calculate hold-off forwind.

The C4 Plus custom knobs eliminate the guessworkfor holdover. Just dial in the known distance anduse the MOA WindMap to determine the hold-offfor a 10 MPH wind. In the example above, at 400yards you simply hold 2.9 tick marks into thewind 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 knob and WindMap 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 knob and WindMap.

How to Receive Your Free Custom Knoband WindMap

1. Determine precisely the load you will shoot- either a factory load or handload.

2. If choosing a factory load and if you haveaccess to a chronograph, measure theactual velocity of the factory load. If you donot have access to a chronograph and/or donot provide a muzzle velocity to us, we willuse the advertised velocity for your factoryload.

3. If choosing a handload, either obtain theactual muzzle velocity or estimate themuzzle velocity based on your reloadingmanual.

4. Make note of the scopeserial number on thebottom portion of theadjustment turret.

5. Log on to www.BurrisOptics.com, enter theBallistic Services section and click on theCustom Knob Online Order Form.

6. Follow the prompts to provide Burris withthe information necessary to produce acustom knob and WindMap for you. Yourfirst custom knob and WindMap are FREEwith the purchase of your C4 Plus riflescope.

Installing Your Custom Elevation Knob

1. It is best to sight-in your riflescope prior toinstalling your custom knob.

2. Being carefulnot to rotate theelevation knob,loosen the threeset screws thathold the elevationknob in place. Liftthe knob up andoff of the scope.

3. Place the customknob onto yourscope, aligningyour sight-inyardage numberto the referencemark on thescope.

4. Apply a smallamount ofdownwardpressure ontothe custom knoband then evenlytighten the threeset screws. Turnyour custom knob about a half-turn counter-clockwise and then clockwise back to yoursight-in distance to get a feel for the amountof resistance to turn the clicker. If you desiremore or less resistance, loosen the three setscrews and apply more or less downwardpressure onto the custom knob; retighten theset screws. Retest and reset the resistanceuntil satisfied.


Parallax/Focus Adjustment– Not available on all models –

Parallax is the apparent movement of the reticlein relation to the target when the eye is notdirectly in line behind the center of the scope.Images from different distances focus in front ofor behind the scope’s reticle. Parallax is morenoticeable with higher magnification scopes.

Parallax is adjusted by rotating the parallaxadjustment ring located on the objective bell.When the scope is set parallax-free for thedistance you are viewing, you should be able tomove your head side-to-side or up and downwithout seeing the reticle move appreciably inrelation to the target.

Windage/Elevation Adjustment Note: Custom knobs must be removed beforemaking any adjustments.The low profile adjustment knobs feature a fingeradjustment for both windage and elevation.Once you have successfully zeroed your scope,you can reset the zero on your dials with thesesimple steps:

1) With turret caps removed, grip knob top firmlyto keep knob from turning.

2) Put pen or othersmall object into thesmall hole locatedon the dial.

3) Keeping firm gripon the knob, use thepen to turn the dialback to zero, liningup the number zerowith the whiteindicator dot. Onlythe numbered dial should move – do not allowthe entire knob to move or else you will alteryour windage and elevation zero settings.

NOTE: You do not have to reset the zero on yourdials for your scope to function properly. Doingso can give you peace of mind that your zero isset, plus you can easily confirm if it has moved atany time, but this step is optional.

How to Use Your C4 Plus Riflescope

Calculating Holdover/Hold-OffThe C4 Plus custom knob ensures that elevationadjustment perfectly matches the ammunitionyou are shooting, and when used properlyeliminates the need to calculate holdover.Determining an accurate distance to yourtarget is key, and Burris recommends using arangefinder in the field for optimum accuracy.Once the distance to your target is confirmed,turn the dial on your custom knob to matchthat distance. For example, if your target is 250yards away, turn your custom knob until 250 isaligned with the reference mark on your scope.Since the scope is calibrated to your cartridge,dialing the yardage to your target allows youto use the center point of the reticle crosshairsas your aiming point – no holdover or under isneeded.

To correctly determine hold-off for wind, firstdetermine as best as you can the wind speed atyour target. Refer to the customized WindMapprovided by Burris that shows, in MOA, theaccurate hold-off value for a 10 MPH wind at aspecific 100-yard increment distance.


6

Using this WindMap as an example, if your targetis 200 yards away and the wind is blowing 10MPH, you will hold-off 1.3 reticle tick marksinto the wind. The wind is blowing 20 MPH?Double the value and hold-off 2.6 reticle tickmarks into the wind. It’s blowing only 5 MPH?Cut the value in half and hold-off .65 tick marksinto the wind.

Installing the WindMapEach WindMap is shaped so it can be easilyinstalled and used in multiple positions such asthe Objective Bell Taper, the Eyepiece, or theRiflestock.

Our recommendation is to install the WindMapon the Objective Bell taper approximately 10° –20° left or right of the top center depending onwhether you shoot right- or left-handed. Thisposition allows you to see the WindMap withyour “off-eye” while viewing through the scope.It also provides for a somewhat protectedposition against scratching.

Locate exactly where you want to place theWindMap and clean the surface of any dust andoils with soapy water or rubbing alcohol. Peeloff the adhesive covering on the back of theWindMap and carefully install at your desiredlocation.

Eyepiece FocusingThe eyepiece can be focused so that the reticleappears sharp and black to your eyes. Followthis procedure to adjust the focus:

1. Point the scope at the sky or a plain wall andtake a quick glance through the scope. If thereticle appears sharp and black, no furtheradjustment is necessary.

2. If the reticle does not appear sharp andblack, take quick glances through the scopewhile rotating the focus ring until the reticlepattern is sharp and clear.

NOTE: Do not look through the eyepiece as youturn the focus ring. Your eyes will adjust to theout-of-focus condition.

Mounting the ScopeC4 Plus riflescopes are available with either 1”or 30mm body tubes; please be sure youchoose the correct ring sizes for your modelas indicated by the end label sticker on yourriflescope box . We recommend using high-quality rings and bases, like Burris Zee Ringsor Signature Rings. Quality componentsensure that your scope will remain safely andsecurely mounted, and will provide themaximum accuracy. Use care when mountingyour scope as damage can be caused byimproper mounting.

Care & MaintenanceThe C4 Plus riflescope is fully waterproof andfogproof. In the event that the lenses aresubjected to dust, dirt or mud, follow thesesteps to clean and protect the lens surface.Failure to remove grit before final cleaning issure to damage lens coatings.

Coarse dirt/debris must be removed from thelens surface. The most convenient way to cleana lens surface is to use a Lens Pen. Position thescope so particles will fall away from the lens,and then use the Lens Pen or soft brush togently whisk away the debris, while blowingon the lens to dislodge the particles. For heavydirt, like dried mud, use a spray of clean wateror lens cleaning fluid to remove the dirt.

Your Burris riflescope will provide reliableperformance given reasonable care andtreatment. All moving assemblies arepermanently lubricated. Only occasionalcleaning of the outside of the scope and theexterior lenses is required. Never disassembleyour scope. If you have any other problemswith your riflescope, please contact BurrisCustomer Service.
