I cant believe this I bought the Mini-14 222 I was asking you about.Took it out to shoot it,I have two five round nags that came with it.But when you fire the gun It fails to cycle.You have to manually pull the slide back to eject the spent cartridge and chamber another round. The gun looks brand new the rifleing looks as if it has never had a round put through it.And its not been shot enough to show any scrapes on the blueing on the slide.It shoots better than I can.I bought the gun used I guess as is.I dont think the owner was aware of the problem.But it has sure caused me a great deal of distress. I called Ruger and they said to make sure the clamp at the end of the hand guard was slid all the way back,and make sure that the four hex bolts were on tight.I havent had time yet to check it out.Does anyone have any suggestions in case Ruger was wrong.They concluded the discussion saying that it seemed that all the gas was escaping some where and not cycling the bolt. Any help would be greatly appreciated. Thanks in advance.
