semi catastrophic failure

[rabies]

sooo i will let the pics talk and you guys tell me what i should.

i heard a "pop" at the ejection port cover(not like a normal pop)

maybe the rd was fully chambered idk.

pulled this exploded casing out.

and whats next to it is what fell out of the bolt.

this is the bolt. you can see the mars shaped hole (missing piece that fell out)

now..i thought wow..that sux. gun is broke now..

dropped mag. functions check. all is well.

another mag. failure to fire...cleared, another rd chamberd.

fired and ejected and chamberd another rd..then fired...

worx jus fine...minus one detail.

when i drop the mag, and pull the charging handle back it wont pull a rd out.

a rd in the chamber only comes out if fired, then it ejects.

but no manual ejection... ?????

im guessing thats what broke and fell out?

can i buy this part? it looks broke in half

Will you please upload a bigger picture of the action directly to the forum

I blew the picture up and it looks like the back of a round blew out taking a piece of the bolt assembly with it. The front 1/2 of the firing pin is out, and a piece of the bolt structure. DON'T FIRE THIS GUN ANYMORE. Send it in and let them repair it.

im unable to make bigger pics, i can however take better pics,

the rd is split open at the rim area.

firing pin?

but it fires jus fine still.

send it to? walther? umarex?  hk? lol too many names.

maybe jus take it to a 30yr experienced gun smith? im sure he can find a new part.

the part that fell out came out of the hole next to the firing pin area.

im guessing extractor? gun functions %100 besides the manual (pulling the charging handle back) to get a rd out without firing it.

hard to explain. i can upload better pics after work. and il drop it off at a gunsmith i know and have him look at it and post back with what he says(im sure he will have a more intelligent explination that mine)

What brand was the Ammo that caused this?

[rabies]

standard federal red box.

i think it was from being real dirty, a round that possibly had a bent nose and it didnt fully close..thats my gues and it blew up outside the chamber.

anything bigger of a caliber the whole gun would have been ruined..

[rabies]

$26 for these little parts  >:(

was self explainatory to reassemble with the new parts

barrel made the whole job hard. hard to remove the barrel without hammering and damaging the soft aluminum

put these on

here it is all put back together

i fired around 200rds yesterday out of it. seems to work jus fine. no failures besides the velocity spring needs wound up more.

Is the Outer Barrel Sleeve pressed into the Receiver ?

[rabies]

about 1" it is. then the barrel nut sqeezes the barrel down onto the receiver.

however  ... :/ ..... in the middle of the barrel there is a lump.

and the barrel has to be pressed in and out of the sleeve.

like an idiot i used a hammer to get it in and out. it took quit abit of force

Ok, so this justifies building a Hydraulic Press even more to work on this Gun, if I have to, and all my AK 47's.  Thanks for all the info, hopefully I will never have to pull the Barrel apart.
