Check the listing for details. Vortex Diamondback Riflescope Throw Lever. Condition: New. Listed at 16.99 USD. Scope throw levers are devices that mount to the magnification ring of your scope. Instead of having to grasp the ring of your scope, you can grab the lever and quickly and easily get to the magnification you need without having to take your eye from the scope. These scope throw levers are 3d printed by me. They are designed for quick and efficient magnification transitions and one-piece constructed requiring only one bolt to tighten for quick installation. I test each design on the scope its intended for to insure proper fit. The levers are 3d printed using ABS plastic. ABS is superior to PETG and PLA that you will find in other manufacturers throw levers. ABS has a higher softening point than other plastics and will not degrade like the others in UV light. ABS is more difficult to print vs other plastics, and requires a much higher quality 3d printing process. This throw lever will fit the following scopes:- Vortex Optics Diamondback Tactical FFP 4-16x44 Riflescope- Vortex Optics Diamondback Tactical FFP 6-24x50 Riflescope
