Burris Synergy Knob Standard Features The Burris Optics Synergy Knob Standard is built around Burris s Knob Synergy system which lets shooters seamlessly swap between elevation and windage knob styles on compatible Fullfield riflescopes. Because the knob attaches to the existing scope rather than requiring a new optic a hunter can adapt the same riflescope to different hunts or disciplines simply by changing the turret. Spinning the custom elevation turret to the distance being shot and then squeezing the trigger replaces the need to estimate holdover or calculate MIL or MOA corrections in the field. That simplicity is exactly the point of the Knob Synergy platform putting precise elevation control in the shooter s hands rather than in a mental calculation. Machined from aluminum and finished in a matte black that matches the rest of a Fullfield riflescope the standard turret is spun in Burris s Greeley Colorado facility alongside every other custom knob the company produces. Its matte finish resists glare in bright field conditions keeping the shooter s attention on the target rather than a shiny turret. Upgrading just the knob rather than the whole optic is a cost effective way to add custom ballistic dialing capability to a scope already in a hunter s collection. The Burris Optics Synergy Knob Standard is a straightforward purpose built upgrade for Fullfield owners available at GrabAGun.
