Sightron SIII Throw Lever

Upgrade your Sightron  optic with our Sightron SIII Throw Lever, speeding up magnification changes and target engagements without breaking the bank. Throw levers are especially useful in a number of different scenarios including but not limited to precision shooting competitions and cold weather hunting.  Our standard polymer Throw Levers are printed using one of our industrial oriented 3D printers. . Our levers are proudly printed in the USA from a custom made durable Nylon 6 material, and feature a metal thread insert for increased strength when tightening. Easily installs in a minute or less. Nylon 6 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.

Available in the following materials:

Black Nylon

FDE Glass Fiber Nylon

More Information About FDM Printing.

Fused deposition modeling (FDM), or called filament freeform fabrication, is a 3D printing process that uses a continuous filament of a thermoplastic material. Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the growing work. The print head is moved under computer control to define the printed shape. Usually the head moves in two dimensions to deposit one horizontal plane, or layer, at a time; the work or the print head is then moved vertically by a small amount to begin a new layer.
