The granddaddy of all backup sights, the MBUS Sight – Front provides lightweight, rugged polymer reliability for those times when your primary optic gives up on you. It’s ambidextrously activated by a push-button or levers on the side of the sight’s body. The elevation post is quickly adjustable with the included adjustment tool or a standard A2 sight adjustment tool.

Made in the USA.
