AR BCG Failure to extract

[Tony617]

I took my home built AR to the range today and shot 6 rounds. The 6th round failed to extract and the BCG was jammed forward and I could not pull the charging handle back. I knew there was no live round to I took my rifle home. I took off the stock, spring, and tube and put a cleaning rod in and used a rubber mallet and gave a gentle whack and the BCG is free and the case ejected.

I need to take gas tube off and take off the barrel nut since the BCG is stuck in my upper and my BCG is jammed. I cleaned the barrel with solvent and used the bore brush too but I still see some preservative in my feed ramps when I took it apart today. I used EWL weapons lube my lubrication and use CLP for cleaning my barrel and BCG.

I also took my my hand guard off and barrel wasn't damaged from what I could see.

Broken extractor pin. Been there.

 

[Kruel J]

Or a general BCG fail. My money is on the extractor pin.

The extractor pin breaking will/can cause a jam like this?

You bet! The extractor and failed pin will cause a mess inside the upper. Broken bits along with a now disengaged extractor will most certainly jam up the works. Again, I've been exactly here.

Ahh, good to know.

So how to I get BCG out since my upper and lower are jammed together. The pins slide out but I cannot separate the upper and lower receiver.

Thank you

Is your BCG in the forward position? If it is im not sure how you cant break the rifle down.

 

[Kruel J]

Your OP says your BCG is free?

 

[Kruel J]

You're 2nd pic shows it rearward.......

Yes it is free now but my upper and lower do not come apart because of the BCG failure.

Well you have to push your bcg forward. It looks like you removed the butstock??

What's the make of the BCG?

What's the make of the BCG?

Spikes from the logo?

Are you able to push the BCG forward further into the chamber, because from the previous photo, or is the BCG failure making that not possible? If you are able to pull both take down pins pins, and have removed he buffer tube, it appears that literally nothing is stopping you from disconnecting the upper from the lower except possibly the safety mechanism, from the photo, even with the BCG not fully in the chamber it looks like you could just pull the upper forward and it would come off. What's stopping the upper from moving at a 15 degree angle off the lower?

Yes it is a new Spikes Tactical BCG.

Do you still have a picture of the fired case? Please post.

It is a PSD 55gr XTAC round made in 2012.

Can you post some clear pics of the primer area...something looks suspect, but the pic isn't clear.

No unless I can take round wooden rod and use a rubber mallet to push the BCG forward. Is the steel barrel hard enough to do this even? I am willing to sacrifice my upper receiver and I just don't want to damage my lower receiver.
