Burris Synergy Advanced Capped Knob Features The Burris Synergy Advanced Capped Knob is built around the Knob Synergy modular turret system which lets owners of compatible Fullfield riflescopes change out elevation and windage knob styles to match their mission rather than being locked into one factory configuration. Its capped design covers the adjustment dial protecting zero settings from being bumped or shifted during rough handling in the field. The knob still provides mechanical zero-stop capability so a shooter can return the turret to a true zero quickly and confidently after dialing for a shot. Smooth repeatable adjustments under the cap keep tracking consistent across repeated use. Machined from aluminum and finished in a durable matte black coating the Advanced Capped Knob is built to withstand being thrown into a scabbard dragged through brush or otherwise knocked around during a hunt. Because it is a direct swap for compatible Fullfield riflescope turrets hunters can upgrade their knob system without buying a new scope outright. All Burris custom knobs are spun in Greeley Colorado reflecting the brand s continued investment in domestic turret manufacturing. For hunters who want to protect their zero in harsh conditions while keeping precise repeatable adjustments the Synergy Advanced Capped Knob is a worthwhile upgrade for sale at GrabAGun.
