When was Burris Optics founded?


The Burris Company was formed in 1971 and named after its founder Don Burris. Burris was a design engineer with Redfield, a Denver-based optics company, who believed he could build a better riflescope than what was currently available.

During his 12-year career with Redfield, he focused on product design and management and was responsible for many industry innovations such as:

  • The first constantly centered non-magnifying reticle in variable power scopes. a design used in 99% of all scopes today
  • The first 4-12x and 6-18x riflescopes
  • The Redfield Accu-Range trajectory compensating dual reticle scope
  • The Redfield Wideview riflescope

During the company’s first four years, Don Burris’ new company produced rings, bases, and open sights, but it wasn’t long before he was back to the design and manufacture of sporting optics. The company’s first optic was a riflescope called the Fullfield, which he began to market in 1975 and it has grown to be an industry icon that is still manufactured today.

Although Don Burris passed on in 1987 the company that bears his name continued to grow and be the first to market with a number of innovative products. It was acquired by Beretta Holdings in 2002 and became part of the Beretta family of companies. Today, the company’s product line includes hunting and tactical riflescope scopes, red-dot and reflex sights, and a complete line of rings and bases.

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

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.

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.

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.

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 like Burris use larger internal lenses. That gives the scope better optic quality but limits the travel more. All maximum adjustment travel specifications are clearly advertised and vary from scope to scope.

To illustrate: There are 2 tubes, one inside the other, which hold all 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.

Can I use heat cure Cerakote on my scope tube?

No, the high temperatures and vapors created can damage components on the optic.

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

Try to take your firearms or bows into your home daily 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.

Why does my reticle move down when my turret says UP?

When adjusting your turrets, focus on altering the bullet's impact point rather than your initial aiming point. For instance, if you're aiming low and adjust the elevation turret 'up,' the reticle should physically shift downward. However, this adjustment is made so that you have to raise the barrel to realign with the target. Raising the barrel moves the point of impact upward, bringing it back on target. This process may be perplexing during the initial bore sighting of the riflescope, as it's the only time when you need to consider physically moving the reticle. Yet, once you start shooting and concentrate on shifting the bullet holes downrange rather than adjusting the reticle, it becomes much more straightforward.
