Primary Arms ACSS 1-6x & 1-8x Throw Lever

Upgrade your Primary Arms optic with our Primary Arms ACSS 1-6x & 1-8x 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.

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.

    Great product! Wish I had ordered one before I finally decided to. Makes transitioning from 1x to 6x much faster and smoother. Price can’t be beat! Ordered on a Thursday, shipping notification within the hour, received on Saturday.

    I use this lever for my 3-Gun competition AR15 and it has worked flawlessly for years. Trust me when I say it does not get treated lightly. It is tossed into dump barrels, dropped, and slid across tables all day long, and the lever has never loosened or slipped. I can wholeheartedly recommend this product, especially at a fraction of what the other throw levers cost. The guys at MK Machining are awesome as well! Fast shipping, excellent service!
