Craziest Failure I've Ever Seen (No Pics, Sorry)
So I figured I'd post a story from today's range session. I recently purchased a BCM carbine and sold my previous RRA carbine to my friend who's just getting into guns. He, literally, has never shot a firearm before so I took him through the whole safe handling spiel.
Well, he loaded up his magazine and inserted it into the rifle. He then grabbed the charging handle and gently pulled back the charging handle and gently rode the charging handle forward (instead of gripping and ripping like I had explained). He then hands me the rifle and says something is wrong. I look at it and notice the BCG is only 1/2 way forward. I can see a round had worked its way somehow ABOVE the BCG. I really couldn't tell what was going on so I locked the charging handle to the rear, pulled out the magazine, and observed the most F*ed up thing ever. The live round had WEDGED itself BETWEEN the upper receiver and the gas tube. The gas tube was somewhat bent downward and causing the gas key on the BCG to hit it thus preventing the BCG from going forward all the way.
I was dumbfounded....never seen this before. I removed BOTH takedown pins and was able to get the upper receiver off. From there I had to take a large flat head screwdriver and basically pry the round loose and it fell out. The bullet had shoved itself 1/2 way into the shell casing so it was ruined. I re-assembled everything and still noticed the BCG wasn't going forward all the way. I took the upper back off and noticed the gas tube was bent downward slightly so I applied some light pressure to it and was able to get it back in place. I also noticed that because the gas key was hitting the bent gas tube, the gas key opening was chewed up slightly but nothing too bad. After all was said and done, everything worked fine. He put about 150 rounds through the rifle without any issues.
It was related to him being soft with the charging handle and riding it forward which caused some sort of feed-related failure but damn...that was some crazy stuff. Anyone ever experienced this?
It should also be noted that I first attempted to mortar the rifle on the butt stock to dislodge that round but that didn't work. However, it did cause the butt stock to now be completely stuck. I think the spring loaded pin that locks it in place got bent?? It is the RRA "Operator" stock. No biggie because he has a Magpul MOE on the way but I want to figure out how the hell to remove it!
