Wilson Combat Back-Up Sight Set Features The Wilson Combat Back-Up Sight Set is machined from mil-spec hard-anodized aluminum in the USA giving both the front and rear sights the durability to withstand heavy range use and hard field conditions. Each sight folds down to a low profile when not in use and clamps onto any standard Picatinny rail making installation straightforward on virtually any AR-15 or AR-10 upper. A positive upright steel locking mechanism holds each sight rigidly in place once deployed ensuring consistent point of impact shot after shot. This rugged construction makes the set a reliable addition to a duty or competition rifle that needs a dependable backup sighting option. The front sight features a standard A2 front sight post with elevation adjustment and is compatible with most aftermarket front sight posts giving shooters flexibility to fine-tune their setup. The rear sight is designed with an anti-snag low-profile body that is finger-adjustable for windage and it offers a dual peep aperture with .200 inch and .075 inch openings to suit different lighting conditions and target distances. Both sights deploy manually and fold flush when a primary optic is in use keeping the top rail clear without removing the backup capability. Together they give AR shooters a proven American-made iron sight solution for when a red dot or scope goes down.
