My AR-15 is Jamming... WTF?

[••SpraynPray••]

Last night while looking over my ar15 I decided to cycle a few rounds from the mag through the rifle with out firing. (was bored I guess) I noticed one round cycled then the second and then on the third pull..

Wham!@ blam %^(* jam! (maybe not that dramatic... but still) Blam @$** JAM ***!

I pulled and pulled and pulled on the charging handle with no success. I took the upper off the lower and tried to pull agian, still nothing. That leaves magazine malfucntion outa the question. I took a flat head screwdriver and used a bit of leverage to dislodge the bolt&charging handle from its stuck location. It didnt take much at all which confuses me because I pulled as hard as I could and it didnt budge, but with a small amount of well placed leverage it *poped* right out.

After removing the round and reassembling the gun, I pulled the charging handle and with no issue it went all the way back and sprung forward.

I reloaded the magazine with the two rounds that cycled through before and put the magazine back in then pulled the charging handle. (Just to see if i can duplecate the problem, I certainly duplecated it) This time no rounds cycled it just jammed. so now im like wtf..

Anyone have any idea wtf I did? Also I just got back from the range the day before and I put maybe 100 rounds through it with no prob.


Charging handle pulled back with the mag in.

ofc =D

Rawr cant open it.

took it apart and got it to open this far.

Used the flathead got it open.

opend it half way, the round didnt seem to have any damage.

then a final look inside.


Ill post the rest of the pics later tonight when my email wakes the F up and recieves them from my phone =D.

Thanks in advance for any help!!

Because it has to be said - never run live ammo through your rifle at home for function checks, get snap caps.

I'd say make sure your ejector claw is good n clean. And cleaning the chamber can help too - shoot any poly-coated steel ammo recently?

Yeah, ditto to never ever chambering live ammo in your house. Bad idea. That said, I had a similar problem while shooting Wolf ammo, only it was a spent casing failing to eject while I was at the range.

I'm not 100% sure anything is wrong with the extractor or the ejector, since you're reporting that it was hanging on with a deathgrip to the casing. (In case you're confused, the extractor is the claw, and the ejector is the little spring loaded button that presses on the cartridge)

Seems more like there is something wrong with the chamber itself, so I would scrub the living snot out of the chamber. Gunk loves to get stuck all inside there so give it a good cleaning. Otherwise, I'm gonna wait to see the rest of the pics before I say any more.

From that picture it looks like the round (at the rear) is too deep in the magazine. If the bolt were to come forward and not catch the rim it would contact the round about mid way up the case and jam it.

Also - if your bolt is locking back when pulling the charging handle back (and there's ammo in the mag) - I would lean towards a magazine issue first and foremost.

It's funny, I was just thinking the same thing: the magazine. OP, if you haven't already tried a different mag, do so. Try full mag, half mag, and 2 rounds. Also, try different ammo.

What do you & MTech do go outside load your weapons
& then bring them back in the house for home protection?

I guess that's a good idea that way if you do have an
accident at least you shoot a neighbor instead of a family member..lol

The key here is "function check", not loading a gun that is fully functioning and operating normally. If your gun is not operating properly, don't use live ammo "check" and use a dummy round instead if you must do it at home.

I keep a few rounds with no primer/powder and just a head crimped in for this - I just mark the cases with a sharpie over the headstamp.

Now when you used that keyword
that made all the difference
