2 month old AK replaced under warranty passed go no go gauges right out of the box ..........2 months later some miss fires [ammo checked ] and doubling [90 rounds out]. Now the carrier will not close on a go about a quarter inch from trunnion same as no go gauge ,chamber brush cleaned and looks good along with barrel rivets . It is on its way back to riley again for another new one but any thoughts. Ammo ,gauges etc work fine in my zap m 70 . Seems i am cursed with the riley BUT blessed too ......its more than 2 years out of warranty and they have not charged me......yet
