The Samson STAR SIG 522 rail is an excellent upgrade for the popular SIG 522 rifle. It makes no permanent modifications to the rifle. The Star SIG 522 quad rail is machined from 6061 T-6 aluminum and hard anodized black to match the finish of the rifle and protect the accessory rail from corrossion. The SIG 522 accessory rail has four MIL-STD 1913 Picatinny rails to take any of a vast number of accessories. Weight has been kept down by the drilling of vent holes that also allow the barrel to cool. The top rail forms a continuous length of rail with the receiver rail and is 19 inches long. The whole unit only weighs 17.7 oz. and is very easy to install. The SIG 522 accessory rail will make a great little rifle into a versatile weapon system.
