FAB Defense FBS Front Back-Up Sight Black Folding

Description

Product Overview

The FAB Defense FBS Front Back-Up Sight is a low-profile auxiliary front sight designed for AR-15 / M4 / M16 rifles. It mounts securely to any 1913 Picatinny rail and provides quick, tool-less front pin elevation adjustment. The ergonomic front shroud helps center the sight image when used with a wide range of rear sights, and the low folded profile helps prevent snagging on gear, webbing, and brush. A spring-locked deployment mechanism keeps the sight positively in place when deployed.
