Flame ot of ejection port
5/28/2012 5:05:28 PM
Some background first. I went to the range on Friday and was cleaning my gun afterward and noticed the bolt rings were mangled. Best discription of how they looked were like circular fish hooks or suture needle. They were also bent. Ordered some replacements from Bravo Company online plus other replacement parts, and then went to the local Class 3 here on Saturday to get some rings so I could shoot today. In speaking with the owner/armorer at the shop we attributted the blown rings to my gun being over gased. We replaced the rings and installed a H2 buffer in place of the standard buffer. The gun is currently in a AR pistol configuration while waiting on my stamp to SBR it. It has a pistol buffer tube installed at the moment vice a standard length mil spec tube.
Now fast foward to today - I have three new bolt rings rings and an H2 buffer installed and it FTE's on the first round combined with a FTF. Prior to replacing the rings and buffer it was running fine with no issues. It occurred with a P-MAG with green tip 855. I cleared it and it ran ok for a few rounds and then another FTE and FTF. Had one more FTE later in the that mag if I remember right. After that I inserted a 60rd Surefire mag with XM193 and had no further issues. Left after the 90 rounds so I could go clean and inspect. The bolt rings are fine. In that parts kit coming from Bravo Company I ordered online I have their BCM extractor upgrade kit coming. Currently there is no o-ring under the extractor. Also for background with the previously installed standard buffer it was kicking the brass out to the 1:00 - 2:00 pos to 8 or 10 feet. Now with the heavier H2 buffer they are consistent at 3:00 pos at about 4 - 6 feet.
At McDonalds after the shoot my wife said she was not sitting next to me at the bench because it was shooting fire out the ejector port. Almost choked on my big mac. I was thinking because of the flying brass. Any thoughts?

Yep exactly according to the wife. I didn't notice it while shooting.
