I have a preban Olympic A2 in very good working order. Lower is circa 1990 production with SGW stop sign logo. Entire rifle rebuilt one year ago with 20" A2 kit from Olympic. A2 flashider, bayonet lug, FORGED lower. The upper receiver has been fitted to the lower, I just cleaned up the bottom with a fine file as the fight was really tight when I rebuilt it and wanted to take a little pressure off the rear pin. $700 to your FFL. This rifle is totally, 100% reliable and very accurate. Has at the most, 2k rounds through the new barrel and I doubt that many. Barrel is not chrome lined.
