Posted this in the troubleshooting section, but then realized no one posts/reads that section, so I am reposting it here. I bought an AK102 parts set from KVAR and delivered it to Global Trades to build it up. After a couple of months, I picked it up on Friday. It looks very nice so I took it home and went to do a function test and a .223 round will not fully seat into the chamber by hand. It feels like it is bottoming out on something. It needed about an 1/4th of inch to go before it would be fully seated. Thinking it needs the carrier to slam it home, I fully assembled it, loaded 5 rounds in the mag and did another function test. This time I pulled the cocking handle back and let it go allowing it to fully slam into the freshly stripped round. The carrier was at least a half inch from fully forward, actually more like 3/4 of inch. I then thought that maybe I was sent a 5.45x39 barrel so I hand loaded a round in and it wouldn't go very far at all so this is a .223 barrel. Anyone have any clues as to what would be causing this issue? I really thought that Global Trades would do a basic function test before allowing this one out. If I didn't do a function test, I could have had a really nasty day. |

Barring something in the chamber, debris, dirt gunk Etc, and if the is known good ammo - I would be back on GT's door step Muy Pronto. Do you have access to go-no guages for 223/556 - a quick visit to a gun shop or board memeber close by might help you assess the situation so that you are speaking to GT - with good information about your problem. |

It is clean and I don't have access to go-no go gauges (I really need to get some). I am definately taking it to Global tomorrow at 9:00AM (will be on their front porch waiting). I was just wondering if anyone has any ideas. It is very confusing as it feels like the round is bottoming out in the chamber, but I can't see anything on the outside that looks like it is hanging it up. |

Check the chamber for a separated case head. Get a cleaning brush ~.30 cal and a rifle cleaning rod. (NOT THE AK ROD!!) Stick the cleaning rod in the barrel WITHOUT the brush on the rod. Push it through the chamber and our the end. Screw on the brush and pull the brush into the chamber. If you can give the brush a turn as you do. Push the rod back out the chamber and see if there is part of a broken case on the brush. Sometimes they are very difficult to see by looking in the chamber. Sounds like the symptoms of a separated case. KyARGuy |

UPDATE Took back the rifle two days ago and now it is in my hands in perfect working order. Global Trades has a few different local builders do their builds and the one that assembled mine was Andre. Apparently, there was a miscommunication on who was to test fire and it was put in my hands prior to a test fire. Turned out that headspace was off and it was promptly fixed and returned. So long story short, Global made it right and did so extremely fast. |
Don't know.
I will try and get pics tonight. It's not always an easy task getting pics with a 2 year old running around like a crazed maniac. |
Well, this sounds not good to me. The headspace on this gun was waaayyyy off, lucky for you. Had the headspace been closer to spec, but still out prior to their testing, the bolt could have almost locked up and blown the gun apart when you attempted to fire it. Lawyers love this type of thing to jump on. Count your lucky stars that you are here to tell the story.......

Guess I spoke too soon... Today after work I took the rifle to the range for some testing and guess what? Still problems. Loaded up a magazine, pulled the charging handle, let it go and it fully chambered. Pulled the trigger, it fired, it ejected, but the carrier didn't fully go home. This happened in about 50 rounds out of the 60 I shot through two separate mags. It had about 1/4 of an inch to go when it stops. All it takes is a slight nudge with my index finger and then it will fully close OR depress the mag release and pull the magazine out just a little and then it will fully close. Sounds like the bolt is dragging on the magazine. It is going back again tomorrow... |
| Headspace is not adjusted on an AK like it is on many rifles. My understanding is that major headspacing issues can only occur with the barrel/trunnon/bolt are not matching. I would check all the serial numbers. If it was a matching kit, Its very concievable that they got the trunnion or barrel mixed up with another gun they were building. Hell, they could have given you a worng caliber bolt back etc. |

check your extractor and hammer,..when i built my ak-74 the extractor was a bit to big and dinded on the bolt causing problems,....once i got that fixed it was the g2 hammer binding to much on the bottom ot the bolt carrier,...a min or so with a file fixed both,.. before i even test fired my rifle i lubed everything up and worked the bolt back and forth at least a few hunderd time to get everything semi worn in and ready |

OH LORD! I took it back to GT today and it was a minor fix, BUT, when he shot the rifle he kept seeing split cases and said there is still something wrong with the headspace. I have no idea what is going on, but I am starting to get nervous about my build. I think one of the problems is my front end didn't come with a front trunion so I had GT use one of theirs. If it had come with the trunion already installed, I bet I would not have had any headspace problems. He said that he will try to have it ready by next Wednesday. I'll let everyone know how it turns out on the next episode of "As My AK Turns" |
