One of my friends got his Cx4 Storm in today, so we all went shooting. My friend was shooting and on the last round of the magazine, it double fed. I took care of that problem thinking nothing of it really since that's not a totally uncommon malfunction. Later on, I was sighting in my new red dot sight and on the fifth 5-shot group, my Carbon 15 Type 21S quit going "bang". I took a look and the bolt wasn't totally forward. I tried to pull the charging handle to eject the round in the chamber, but it wouldn't budge. I took out the magazine in case there was a misfeed, but that didn't appear to be the case. The bolt still wouldn't budge. I sat it on a table and took the lower and upper apart. After that, I tried to pull the charging handle back to remove the bolt carrier from the round (hopefully), but it's completely frozen in place. Any ideas on how to fix this? The bolt isn't totally forward (it's about 1/4" short of locking), but it's frozen solid as far as I can tell. Any help is appreciated. |

I had my .470 do that with a bad dummy round and no amount of banging on the butt stock worked. What I did was take a flat bladed screw driver and while padding the front of the ejection port with wood, I pried back on the carrier, NOT THE BOLT. BE VERY CAREFUL OR YOU CAN DAMAGE THE EJECTION PORT! The carrier moved back with little prying effort. I had beat the crap out the stock banging it on the ground to the point I was afraid it would split (wood stock) if I hit it any harder and I have never had to hit a stock as hard as I was hitting this one. Since yours is a pistol with not stock, I would be careful banging the buffer tube too hard. |

I had a blown primer lodge in the track the bolt carrier key rides in. It wasn't obvious what had happened at the time, but it produced the same thing you're describing. I did pretty much what you did, made damn sure there wasn't a live round in it and separated the upper and lower. I tapped the bolt forward from the back with a big rubber mallet and pulled it back with the charging handle. After enough fiddling, the primer dropped out and the bolt worked fine. If you have to pry, I suggest you do it from the bottom where the marks won't be seen. Good luck. |

Good news. With the help of you guys and a friend I have that used to be in the marines, the bolt is now clear. I took the upper & lower apart and used a flat blade to pry the bolt carrier backward about half an inch. After that, the charging handle was free and could move the bolt out for damage inspection (there was none) and cleaning. Fortunately, the screw driver didn't leave any marks. I guess that's one of the reasons why carbon fiber receivers are nice. No scratches at all, but even if there had been nobody would have seen it. The material is the same color all the way through. Thanks again, guys. |
Did you figure out what caused the jam? How did the cartridge look after you got the bolt and carrier to pull back? |
