Revision II design for a stronger, more aesthetically pleasing product! Upgrade your Vortex Viper optic with one of our throw levers, speeding up magnification changes and target engagements without breaking the bank. The VTX A model fits Vipers with a hard magnification ring that has longitudinal grooves. Vipers with a stippled rubber magnification ring need the “VTX R” model, and a Gen II Viper lever is coming soon. Our levers are proudly printed in the USA from durable PETG polymer, and feature a metal thread insert for increased strength when tightening. Easily installs in a minute or less, and has a lifetime warranty.
