Help! Ar BCG jammed.

[zombieflanders]

Took my ar 2 my friends house in Vegas 2 do a little 30rd blasting. About 15 rds into the first mag, she locks up. The bolt is stuck bout 1/4 or so from full battery. Can't rack the charging handle, forward assist does nothing. There's no visible obstruction that I can see. The bolt is just stuck there. I can't even crack her open 'cuz the bolt is part way into the reciever extension. Any ideas?

SPORTS first, Live round in the chamber?

Sounds like a primer popped out and lodged itself somewhere in the receiver. Remove the mag and look up into the mag well to see if anything is stuck in there. If you cant see whats causing the obstruction the move on to step 2.

If its a live round dont do anything if you are at home! If its not then I suggest the mortar drill. Pop the mag out, collapse the stock and pound butt into the ground HARD while simultaneously pulling on the charging handle. Its important that you collapse the stock first or you might break it.

Not sure if it's a live round or not. Don't know if the gun was ejecting or loading when this happened.

If the bcg is part way in the buffer tube, then you can try to remove the magazine, remove the front pivot pin and rear take down pin, then gently slide the upper receiver forward to see if it gets it out. I've had this happened to me because of double-feeding, and that's how I was able to get it out and remove the ammo.

Maybe a broken firing pin?

If you dont know treated as it was a live round ,better safe then KABOOM. As J Rock stated if your at home DONT DO ANYTHING. DUH I forgot the important thing, +1 on Vtec44 solution specially if its only 1/4 of an inch, but dont do it at home.

If you have a plastic prybar (often found in electronics stores, such as those for opening the iPod/iPhone, etc.), you could possibly pry the bolt open/back by catching its shoulder and levering against the front edge of the opening in the upper receiver. Do it gently and slowly, and keep trying to rack the charging handle as you wiggle the BCG free. Eventually, you should be able to rack it to clear. This probably safer since the firing pin is blocked while the BCG is open.

Actually, this sort of thing happened before, and the instructor simply pressed forward (hard) on the BCG with his thumb to push it into full battery, so it might be as simple as that. Later on, we found that the magazine had misfed two rounds on the same side of the magazine somehow (I don't know how) and that the extra pressure exerted by the taller-than-normal stack made the bolt harder to rack. Be careful with this route--the round could be fired with the BCG closed.

the prybar idea is a good one but Id remove the stock and unscrew the buffer tube and attack the BCG with all the above removed.

remove the stock and unscrew the buffer tube and attack the BCG with all the above removed.

I would do this

Try pulling the handle, it is going to take a strong person to do it, but the handle should retract with lots of pressure applied to it while pulling it to the rear.

take the mag out. switch to safety, if you can, your hammer is cocked with a live round, if not your dealing with a round that has been likely fired and stuck. STILL TREAT IT AS IF IT WERE LOADED OF COURSE.

hold the charging handle with the gun facing up, slam the buttstock on something hard like wood while pulling down on the charging handle simultaneously. May take more force that feels right but works plenty times at the range.

Photos would be dandy.

This might be common sense but always good to mention, DON'T have your head above the barrel while slamming.

similar situation happened to mine, had to use the corner of a table against the charging handle and then hit up on the buttstock. Be careful

[dchang0]

Gotta be careful not to bend the charging handle or break the latch off, though. If going that route, prop the gun up with the stock on the floor and leaning the left side against a table or the wall (watch your muzzle--don't want a discharge into your ceiling or second floor), undo the latch and let the charging handle fall as far as it can (1/4" probably). Then, gently tap the right ear (the side without the latch) repeatedly with the rubber mallet. Increase the force as needed. The buffer spring will try to push the BCG back into battery, but whatever's stuck will hold the BCG in place as you keep tapping. Eventually, the obstruction will clear, and then the buffer spring will push the BCG forward, probably causing a double-feed or some other sort of thing that you can clear normally. The danger here would be a slam fire, if your BCG is capable of doing that.

Is it possible to remove the stock and buffer tube without having access to the buffer retainer pin? I thought that pin goes into a slot in the bottom of the buffer tube's threads...
