Bolt face stuck

[Flashbanggoodbye]

Had a piece of brass jam the bolt face from turning back, jammed against the barrel lands, any suggestions on how to get it to turn back to release? I've removed barrel nut, tried small brass punches to get it to push forward, but not budging..

Pics.   Show us the jam.

Eh, one of these days, you'll post a real pic of the malfunction - then we can really see what it is. Your description isn't very telling. 

Whenever you post up- and get a real pic of this jam - we'll figure it out quick. 

No pics = not much to go on, based on what you described.  Get a real pic of this jam up here, and we'll solve it. 

I'll wait.

Hard to get a great pic, basicly the bolt lock is pressed back against the feed grooves. Not turning back to release the receiver. Firing pin is free moving, 

[jtallen83]

Did you try mortaring it?

 

[Flashbanggoodbye]

Way more complicated then a simple morter solution, the exploded brass in the barrel chamber pushed the bolt face up against the feed lands of the barrel so any force applied down is against barrel steel, and any force applied forward is against exploded brass in the barrel. I somehow have to turn the bolt lock to clear the bullet feed grooves and get it to free up.

The cam pin turns the bolt off the lugs as it moves unless I am not understanding your verbiage when describing the issue. You say "exploded brass" could you elaborate on the explosion?

[Flashbanggoodbye]

Yes, the cam won't turn due to it being pressed back against the barrel feed langes, not sure about exploded brass as it's still in there, but casing before jam was split at base and primer gone, 

Sorry, trying to explain the best i can, if i can get the bolt cam to turn back a little,,, right now it won't move to rotate, either way, i think the brass forced it back so far it is up against the barrel feed, i have the barrel loose and it moves back and forth about 5/16 or so with the receiver, sorta like two cars stuck together in a rear end crash.

Wow.  PIcs don't tell much.  You stuck a piece of brass in the chamber.  If you have a collapsible stock - then collapse it all the way down to closed.  Stand the gun upright, and SMASH the charging handle with a dead-blow hammer, until you unlock that thing.  Yeah, no kidding - you're sacrificing a charging handle, possibly.  Whack it hard, too, numerous times.  You'll unlock that piece of brass.

There is no other way around that ^^^.  Smash it.

So, live round in the chamber too, or explosion and then closed on just brass shrapnel?

[Flashbanggoodbye]

No live round, it fired and jammed. Totally disassembled now, problem found, just trying to figure out how to fix it. Lol.. 

[Knuckledragger]

Like to know what ammo blew up in this. 

[Flashbanggoodbye]

Not sure which brass it is yet, but load was federal match primer, 43grs sw tactical powder, and Hornady spbt 150gr

Not a hot load by any means, i usually load 44.5 grs of IMR4046 with 168 Amax without any problems

Once fired brass, or multiple trips down the road and back?

[Flashbanggoodbye]

Twice fired, from same rifle,  i never load brass more than 3 times, no matter how well it looks. 

AOL was 2.173 i shortened it down a smug due to soft point bullets, i usually aol at 2.174 + - .0005

Well after hours of banging, oil, twisting, the only thing left to do is cut the upper receiver open and get it out. Dam, 2nd receiver this year, first one had machining flaws,

Send it to me. Just finished up @aadavis94 bolt with hopelessly stuck ejector,  ready for the next project.

Maybe it’s all in the name. Flash. Bang. Goodbye.

Put the receiver in a vice with the barrel pointed up. Put a metal bar in the BCG where the hammer comes up to hit the firing pin. Smack metal bar with a big hammer. Worth a try before you cut up a receiver.

[Flashbanggoodbye]

I'm going to try that, thanks, I'm also going to try to take a small dremal bit and make a edge on bolt cam, and get at it with a chisel punch to turn the groove back in line, hopefully it works, if not cutting the receiver is the only way to get to it. Then to figure out why or how this happened, 

[Matt.Cross]

I would see if I could use a standard "L" style anchor bolt in a creative manner to force the BCG rearward via threads.

I would try this or a rod down the barrel? as long as you can confirm cartridge has fired? maybe a tight chamber? or crap peice of brass. good luck. I would also suggest wood as a backer not in a vice. have a second set of hands over a couple blocks.
