Matech Back Up Iron Sights. BUIS. Rear Iron Sights. Solid, robust, and as accurate as your eyes and skill will allow. Elevation markings from 200 to 600 Meters. Adjustable windage.

Charlie's inspects each sight, and assigns a grade.  These are more toward the less than average side the grading scale, average to below average condtition.  100% functional, and have seen quite a bit or wear, and no damage. Generally, you can expect to find wear on the windage knob, and some wearing of the painted elevations, and occsional light rust. 

While not of the lowest grade of used milspec back-up sights, these are very well worn.  They will need a cleaning and some oil.  If we were to return to looking new, we would have take each piece apart, clean, sand and Parkerize, and the effort is not worth the commercial value, so we are offering these at a good discount.
