ZeroTech Optics is offering a year-end promotion in which a purchase of a riflescope comes with a free pair of Vengeance 10×42 binoculars. The deal covers scopes bought on the company website or from dealers and leaves out the 3-9x and 3-12x models.

The code SNW20 takes 20 percent off the entire ZeroTech website, including items already on sale. Customers may put the binoculars value toward a more expensive pair rather than keep the free set.

Scopes begin just over 200 dollars and extend to models that use German SCHOTT glass.
