I have my CZ550 custom 404 Jefferys priced to sell at $2200. on the AR classified...You cannot build one for that price..Its a nice gun with Lothar Walther barrel, English style stock, barrel band front sight and swivel, talley/Brockman QD rings and bases with a pop up peep when the scope comes off...Receiver was surface ground and bases hand fitted, steel grip cap...Real nic gun that shoots everything I have tried into an inch....
