Change it up

The Optum Ring System (ORS) makes it easy to move between eight pin positions with the same ring or swap rings completely to suit your needs. Changing the ORS just requires two screws to be removed with the included hex key. With five pin sizes and three fiber colors there's a combination to suit every need and occasion.

Light Kit Ready

Adding a light kit couldn't be easier with the two 8-32 light ports built into the 29mm Optum. Thread a light into the fiber light port to illuminate the pin or for those who prefer a center-drilled lens or dot, use the angled light port on top to shine directly on the center of the lens.

User Friendly

The Optum is made to be customized to suit your needs. Strip off the fiber cover for maximize light collection, remove the pin and fiber to optimize your sight picture for a center-drilled lens, or thread in an electronic light to boost your pin brightness. With the Optum, you can have it all.

Build It Out

The Optum is threaded on both ends to accept sunshades and lenses. Choose from three sunshades and a variety of lens powers and models when building your Optum scope. With 40+ configurations, there's something for everyone.

Adaptable

Twist open the adjustable fiber cover to let in maximum light indoors or on cloudy days. When the sun comes out and your fiber starts to starburst, rotate the cover closed to limit light access.
