HIVIZ rear sights are machined from solid steel and feature fiber optic LitePipe inserts for increased visibility and faster sight acquisition in all conditions. The Rear portion of the steel sight is serrated to reduce glare. Finish is matte black. Designed for Taurus PT 1911. Gunsmith installation is recommended by HIVIZ. The dovetail portion of the sight is slightly oversized to allow for variance between firearms and fitting will be necessary.
