Windage Adjustment and Flip Design

The windage-adjustable mechanism lets you dial your rear sight to point-of-aim without permanent modifications. At 4.9 inches in length, this sight sits low-profile on your rail while still delivering fast target acquisition. Polymer construction keeps weight minimal—0.07 pounds—and resists corrosion in extended storage. Mission First Tactical engineered this for shooters who understand that redundancy matters, whether you're working with standard rifles or setups like those covered under PC §32100 exempt revolvers configurations.
