Pri Fixed Front sight with thumb Wheel is constructed of T6 6061 hard coat black anodized aluminum.  Front post height is 1.4" from top of the Picatinny rail that is at the same elevation as the receiver.  The Front circle housing eliminates the shadow cast optical sights and the full circle hood increases speed of target pick up.  Front post works on a thumb wheel with retention clicks.  Our front sights are also compatible with our rear sight and the A.R.M.S family or rear sights.
