Great things come in small polymer packages. The MBUS 3 Sight – Rear brings tool-less windage and aperture adjustment to a rear sight that’s ready when your primary optic isn’t. It stows at just 0.55” tall and 1.38” wide on your M1913 picatinny rail and includes ambidextrous deployment capability and two aperture options for different shooting scenarios.

Made in the USA.
