leupold mark 5HD, throw lever

BoneSpur™ throw lever & machined broach screw

Tired of large, big clunky throw levers? Do they get in the way of your field of view when locating your turret position or bubble level?

Our new BoneSpur throw lever is changing the way we view these products. Originally designed for Leupold's Mark 5HD ( U.S. Army PSR, M110 and MK22) military optic programs, this unique and precision engineered lever is now available for civilian use. Machined from skelotonized ultra-strong 7075-T6 aircraft aluminum, the "ringless" ultra-light throw lever boasts a non-obstructive window custom fit for the Leupold Mark5 magnification adjustment ring. The outer surface is machined with our Bone-Saw™ teeth which provide maximum grip for control in any conditions, bare handed or gloved.


• Bone-Saw™ outer spines to enhance grip for maginification manipulation

• Hollow-View™ design, for non-obstructed view of turrets, bubble level and other vegetation on your scope

• Provides optimum control with gloves in harsh conditions

• Ring-less mounting for minimal real estate and weightlessness

• Top access tool point for easy installation and removal

• Ultra-light high strength 7075-T6 aircraft aluminum

• Mil Spec hard anodized finish
