Sig 556 Classic SWAT Patrol

As far as Sig 556s go, this one is the cream of the crop. It's got the factory railed handguard, Swiss folding stock, and rare diopter sights. I've got other Sig 556s as well and a plethora of parts and accessories if you've got one and are looking for anything, or if you would like to reconfigure this one for a different setup/price.
