Coating on Optics

How are Burris optics coated?

All Burris scope lenses are precision ground and fully multi-coated. Every surface of the lens is coated, providing some of the best optics available.

My scope adjustments are maxed out. How do I obtain more adjustment?

This is typically an issue of alignment on the firearm itself, rather than a scope defect. Many variances can cause this alignment issue: bases, rings, drill-and-tapped holes, or threading-in of the barrel at an angle.

There are many ways to correct these alignment issues.

  • If it is a windage issue, use windage adjustable bases.
  • If it is an elevation issue, shim the base.
  • You can also use Burris Signature Rings™ to correct both windage and elevation issues. They will also hold 30% more service area of your scopes tube, and the inserts do not damage your scopes tube.

More information:

Many people notice this issue when upgrading from a lesser-quality scope on a rifle they’ve had for many years. Lesser-quality scopes have much smaller internal parts, allowing for more adjustment travel. Higher-quality optics use larger internal lenses. That gives the scope better optic quality, but limits the travel more.

To illustrate: There are 2 tubes, one inside the other, which hold all of the erector lenses. Moving the adjustments up or down eventually pushes the internal tube against the outer tube wall. See the illustrations showing how a lesser-quality scope can have more adjustment.

How do I mechanically center my scope?
  1. Turn the elevation adjustment dial all the way to the top. Do not force it.
  2. Now turn this same dial down, counting each click until you reach the bottom.
  3. Divide the number in half and click the scope back to that number. (So if you counted 100, click the scope back to 50.)
  4. Repeat these steps with the windage dial.

What should I use to clean my optics?
  1. Carefully remove any debris before cleaning the lenses, to prevent scratching.
  2. Use an air can or soft brush to remove dirt or dust from the lenses.
  3. Then use a cotton-tipped swab with rubbing alcohol applied to remove any debris remaining along the edge of the optics.
  4. With another cotton-tipped swab and alcohol, start at the center of the lens and make a circular motion. Increase the circle size each time until you reach the edge of the lens. Multiple swabs may be needed.
  5. Next use a clean cotton-tipped swab (with no alcohol) to remove any remaining residue from the lens.

For in-field cleaning, we recommend using the Burris lens pen.

Always use scope caps to protect from debris and scratches on the lens.

Can my scope be refinished?

Unfortunately, no. Ring marks are usually the reason owners want to refinish scopes. To prevent ring marks, we recommend…

  • Using Signature Rings™
  • Following the torque specs of the rings
  • Lapping to prevent ring marks

Storing in Vehicle

Can I store my weapon in my vehicle with a scope mounted?

Try to take your weapons into your home on a daily basis to prevent these issues:

  • Prolonged periods of time with fluctuating temperatures can affect your scope’s seals and lubricants.
  • Vibrations from bumpy roads can cause scope mounts and rings to loosen, creating point-of-impact issues.

Waterproof, Fogproof, Shockproof

Are all Burris scopes waterproof, fogproof, and shockproof?


How do I focus my scope?

There are 2 types of eyepieces on Burris scopes. One has a lock-ring system and the other is on the end of a European-style eyepiece. European-style eyepieces include: Euro Diamonds, Black Diamonds, Fullfield II™, Fullfield II Tactical, Fullfield 30™, Fullfield TAC30™, and XTR™.

To focus a lock-ring scope…

  1. Grasp the knurled eyepiece lock ring and loosen by turning the eyepiece counterclockwise.
  2. Turn the lock ring clockwise away from the eyepiece.
  3. Look through the scope at a white wall. Turn the eyepiece until the reticle appears sharp.
  4. Look away from the scope. Now look through the scope again. If the reticle is still in focus, go to step 6.
  5. If the reticle is not in focus, repeat steps 3 and 4 until the scope is in focus.
  6. When you are satisfied with your focus, tighten the lock ring firmly against the eyepiece.

To focus a European-style eyepiece…

  1. Look through the scope at a white wall.
  2. Grasp the rubber eye guard at the end of your eyepiece. Turn the rubber eye guard clockwise all the way against the eyepiece.
  3. Now turn it counterclockwise until the reticle appears sharp.
  4. Look away from the scope. Now look through the scope again. If the reticle is still in focus, the process is complete.
  5. If the reticle is not in focus, repeat steps 1 through 4 until the scope is in focus.

Your scope only needs to be focused once. However, each person’s vision is different, so a scope may need to be refocused when changing users.
