Really happy I found one, completes my SIG collection. Cant wait to shoot it next weekend. For now this PA red dot will do, sadly it is better than the red dot SIG provides. Tossed on a Midwest 556 sight that I had from my 522. Will do for now until I get some MFI MAD sights and an Aimpoint Pro. Also fixed the wiggly handguard that plagues SIG rifles . Probably going to be my only complete purchase for the year. Got a AR lower and hope to grab a few more before Oct 1. This furlough thing is hurting my purchases
