Need some advice on a stuck BCG in a loaded AR

[Rabid]

I built a little chunk of aluminum that fits inside the BCG and hooks onto the lower recess face. It might be kinda tough to get in there depending on the position of the hammer, but looking at your pics it might be doable. Then with a hammer you drive as close to parallel with the barrel as you can and hopefully you can get enough force to drive it out. And as always wear protective gear and point in safe direction etc. I will add a pic here in a second.

Unless you enjoy slamming your AR on the ground risking a vertical discharge.

Good job looking out for his and others safety but the bolt is fully extended and the firing pin can not physically touch the primer like that. If he does not put the spring back in the buffer tube it is as safe as the other options.

Put gun on safe, remove magazine. Put left hand on fore end of gun, put right thumb and one right hand finger on each side of charging handle. With muzzle pointed in safe direction and buttstock collapsed (if applicable) slam butt of gun into ground whilst pulling on charging handle.

From the pic it looks like the buffer detent is riding up into the BCG.

Those are supposed to be secured by the buffer tube. Not sure if that is your root cause or not, but you might want to take a small screwdriver and push it down out of the way while you're trying to break the BCG loose.


ETA: Could this be pushing the BCG up so the bolt isn't properly aligned?

He removed the receiver extension to take that picture - that is why the buffer detent was free to ride up into the carrier.

Thank you guys! I tried the "slam to the ground" technic when I was outside far for civilization yesterday. Did not work though.

I will try the "brass punch" idea to see if I can push the BCG back.

And yes, I did remove the receiver extension to see what was happening in there.

This is worrying me a little boys. Is this only happening on builds, or factory stock guns? I have only owned two Bushmasters and have put a couple thousand rounds through each of them without a single malfunction ever. I kept 'em clean and lubed and they ran any ammo I tried.

I am anticipating on trying my hand at a build in the next year, what causes so many of you to have this issue and what is the cause. A unreliable rifle is of no use to me.

What makes you think this is a large scale problem?

Which is why a mortar will not work now. No way screwing the buffer tub back in is going to capture the detent pin and free the BCG from it's vertical capture. Besides, I see OP posted he did try that first. My first suspicion would have been buffer tube not in far enough and detent popped, capturing the BCG. I suppose the extractor could be jamming up the bolt face in the lugs too.

Barring a cool DIY tool like Danimal posted, I like the brass punch on the BCG face idea. Ensure the detent pin is retracted. Safety first.

This is what I thought too. I don't understand how the OP plans on getting the BCG out at all now unless he can reach through the BCG while screwing in the buffer tube.

OP needs to update this thread with a poll, wait a day, and then tell us what the issue was

How is the detent, that you can push down with your finger, stopping the rearward movement of the BCG in that position? Sure it is going to get a little fiddly now that the detent is not captured when it and the spring pops up in hole of the BCG. When that happens it will stop the rearward movement of the bolt because the spring will get bound up but it did not cause the malfunction and he can still get the BCG out.

Honestly: I have no idea how I am going to fix this one. But one thing for sure, I need to do this outside far from people or in safe place just in case.... Not my garage. I know there is a slim chance the round will fire, but it seems I am on Murphy's list lately.

Worst case: I'll cut the lower if I have to... It is the less valuable part of my build anyway.
