Shrewd Optum Ring System for 35mm and 40mm Optum Scopes / No Pin

The Optum Ring System is the backbone of the Optum system and enables quick and easy configuration of the scope. Keep an Optum Ring System ready for 3D, Field and Indoor with different fiber sizes and colours and swap between them in seconds.

• Optum Ring System (ORS) for the 35mm and 40mm Optum Scope only (The 29mm Optum uses a different size ORS)
• This must be used in conjunction with an Optum Scope
• The ORS makes it possible for shooters to change pin positions, fiber color or fiber size by swapping between multiple rings

• Exterior fiber wrap that captures ambient light for a brighter pin
• Adjustable fiber cover allows precise control over fiber brightness
• Two 8-32 holes for installing a light in seconds
• Eight pin positions
• Threads on the target side for optional sunshades and lenses (only 40mm Optum sunshades will thread into the ORS)
• Removable pin in keyway slot for perfect alignment every time
