Throw levers are especially useful in a number of different scenarios including but not limited to precision shooting competitions and cold weather hunting. Our Pro Series Throw Levers are printed using one of our HP Multi Jet Fusion 5210 printers. This allows us to get the surface finish of a modeled part with the strength and durability of standard polymer levers. Our levers are proudly printed in the USA from durable Nylon 11 material, and feature a metal thread insert for increased strength when tightening. Easily installs in a minute or less. Nylon 11 does not have the tensile strength of aluminum, but is extremely durable and will flex and yield under hard impact rather than damaging or marking your optic. This feature can be useful in a number of situations including shooting competitions and hunting when a throw lever may snag. Our levers feature a lifetime warranty.International buyers ? please note: Import duties, taxes, and charges aren't included in the item price or postage cost.
