Posted 7 Mar 2016 Not Mine: http://www.falfiles.com/forums/showthread.php?t=398089 2.) AR-57 5.7x 28mm upper for AR-15/M4 pistol. Has a 10" barrel and the distinctive AR57 proprietary flash hider. I've only fired 150 rounds through this upper. Comes with TWO original FN-made 50 round magazines. This is a Gen 1 upper, complete, with an unfluted barrel. Includes a set of black UTG rail covers. Bolt is the semi-auto type. These retail for $745.99. I'm selling this one for $675, postage paid to CONUS. No FFL required, but check your state and local laws. Sorry, no shipments for mag ban localities. Note that this upper can legally ONLY be installed on an AR-15 lower that is marked "PISTOL", or on a registered SBR lower! All NFA rules apply! Just one available. Share this post Link to post Share on other sites
