Have a post sample AK 74 built from a Bulgarian parts kit.

The first round suffered a failure to eject. There was a case separation during the extraction process.

The round was of Bulgarian surplus, steel with looks like a lacquer type finish.

Anyway, there is still some of the casing left in the chamber. After repeated attempts to extract the remnants, there is still enough to proclude chambeing a round.

Would attempting to ream the remainder out be the most logical option?

Running out of ideas. We have the barrel out of the trunnion.

Anyone experience this?

Thanks

My Polish Tantal rebuild works like a charm. Nodac Stud receiver. Split cases on surplus ammo is common, but I've never had one come apart. If the case separated from the base you could try a 'tap'. Screw into the shell until snug and tap out with a hardwood dowel. If it slips, screw in tighter. I did this with an M1 carbine and it work nicely.

they do make ruptured case extractors - a 5.56mm USGI type may work.  You might also try a broken screw extractor of the right size - they will often pick up the front end of a case as well - note they are LH thread, so you turn them the opposite way.  You also might try a larger bronze brush on a section of cleaning rod, and spin it with a drill - 6mm/ 270 size in this case.  That can also spin the neck out sometimes.  Now - this may seem a stupid question, but are you sure there is a case neck left in there ?  and that you are not just seeing the front of the chamber ?   Let us know how things come out - so to speak.....

Hi Guys,

There are fragments of a shell casing still in the chamber. We were able to remove fragments. As it now stands, all that is left is a residual of fragmented shell case.

We are not able to insert a round. One can see the fragments of the casing. Ill attempt to get some clear photos. The barrel has been extracted from the weapon.

Thanks for all of the replies...

Drop one of those Ebay Endoscopes($20) in there to see what you have going on. You should be able to scrub fragments out of the chamber.

Drilled and extracted...

Looks like a case rupture and stuck to the chamber, like a spot weld...
