Guest Steven Lumbley Posted February 6, 2013 Share Posted February 6, 2013 Took the benelli m4 out yesterday to fire it for the first time and put about 100 rounds through it. Noticed towards the end my rounds were not ejecting but thought it was due to them being old reloads. Was cleaning it today and took apart the Argo system on the barrel and low and behold a busted O-ring. Customer service is sending me some new ones but has anyone else had the issue or know what the Oring size might be so I can put a temporary on.
