I built an AR-9 Carbine using a Spike's Tactical lower that takes Colt Mags. I'm having failure to eject issues pretty much routinely - stove pipe or caught between the bolt straight in against the face of the receiver concurrent with a new round being fed. Current configuration consists of a standard carbine spring and Spike's T3 buffer with a spacer at the end of spring. The bolt is manufactured to run with either Colt or Glock magazines. I've also run a Colt Only bolt and had the same issues. I've tried adjusting the position/alignment of the ejector with some temporary relief from the FTE but it reoccurs. Any suggestions of spring/buffer weight combinations or other thoughts to help resolve the FTE issue would be greatly appreciated. Many thanks!
