Thankyou fellas, got an email back from Heym USA last week, the bloke there said april 1983. Not sure about Rebel's JFE? bought it from Inverell, northern New South Wales. Was on used guns. Have always wanted a 5.6x50 Magnum, as a kid had a magazine that had European calibres and liked the sound of it. Don't have anything in the 22's, other than a ZKW 465 Hornet. Foxes and roos a little bit too smart for the hornet now. Do all my shooting, of late every night with a 204 Ruger, but like the idea of something a bit different. Hence the 204, everyone has a 222, 223, etc. Just bought a Zoli 6mm Remington as well for a little more firpower.
