Has anyone ever seen an AR jam like this before?

SigSour · Aug 4, 2017

My friends AR had this malfunction and I have never seen anything like it. This happened on the third magazine ever put through the firearm. Has anyone seen this before?

are my eyes messing with me or did your friend chamber a round backwards?

SigSour · Aug 4, 2017

The round is backwards in the chamber, above the BCG. Brand new Delton Sport. He's a vet and very experienced with firearms and said he didn't do anything out of the ordinary.

One more picture I couldn't get to upload correctly.

Could be a weak ejector spring or stuck ejector. Extractor is pulling the case out of the chamber but it's not being kicked out.

I guess I can say I've seen it all now. Your friend should get an award.

A first for me also. There is not enough room for the round to flip 180. I believe it would have to start in the mag that way.

It did not. It was loaded the correct way.

Is there a picture of the empty cartridge outside of the firearm?

Is that a live round? If so, the jam is due to operator error.
Most malfunctions in ARs are caused by three things.#1 Bad ammo, #2 bad mags and #3 operator error. #3 is most often a contributing factor to error #1 and #2.

My theory is its a fired casing that somehow never ejected, or possibly bounced back in (hes a lefty), and got stuck on top of the BCG. Which is odd that a BCG would have a loose enough tolerance to allow a casing to get stuck on top of it. He was just firing at a normal/slow pace and is by no means a beginner.

You need a brass punch and a hammer. Place the tip of the punch at the front of the bolt carrier and knock it to the rear.
If you need help, bring it to me.

He's located in south Florida unfortunately.

If the brass markings on the bolt lugs and bolt carrier were caused from just firing, then he has a problem. His mag is to far up in the mag well. This could br caused by a few things. Bad mag, or out of spec upper or lower.

I was confused, until reply #9, it was referred to as a round, not a case.

BCG tolerance shouldn't be an issue, as a bullet or case neck will fit in the channel above the BCG.

Candyman may have nailed it as those don't look like 3rd mag normal wear marks on the bottom of the carrier.

Yup. Not a common malfunction but learned how to clear it at a WARFIGHTER class. Easy. Stick your fingers up mag well and press the face of the bolt back. While keeping pressure upward chop the charging handle until it seats then pull the charging handle back. The bolt will function as it should and the bcg will move back. The round should fall loose. If not, finger **** it and tickle it. It will fall out.

Yes indeed haha, love the last description on handling this situation. Been a while since I've heard that expression.

Have seen this a few times when dealing with weak magazine springs or binding followers
