The sight arm has vibration absortion properties and allows fore and aft movement for balance and tuning. The most notable feature is the Rapid Adjust Knob and Quick Release that slides the sight up and down. Push the Rapid Adjust Knob in to activate the Quick Release for rapid up and down movement or turn the Knob for precise fine-tuned yardage settings. Axcel extended the amount of windage travel on our super-precise dovetail bar. It has individual windage adjustment lock and an adjustable elevation lock. Pointers can be used for a quick reference when using a multi-pin scope or with a single pin when using the top of the level vial as a second aiming point. Each sight includes 8 metal tapes with 16 scales. The first, second and third axis adjustments are each true, easily, and independently adjustable.
