Purchased this AR9 new in 2016 and it has less then 700 rounds through it. Complaining to the manufacture has gone nowhere, they claim it's a magazine issue. Most recently the rifle started having an issue with firing two rounds at once and then being out of battery. Performing maintenance at home i returned to the range a couple of weeks later the first 2, magazines ran fine. About half way into the third mag the rifle went full-auto firing four rounds. After clearing two spent casing wedged together I chambered another round without seeing it the bolt was out of battery and blew out the magazine. Initially i didn't think there was any damage except to the mag. upon further inspection during cleaning i see the ejector is now bent away from aligning with the magazine. Would gently bending it with pliers back into position work, or should it be replaced. Also installing Kaw Valley buffer/xp-spring.
