Bonehead of the year award goes to me, need help!

So after a shooting session with my FN ar today I striped it down cleaned and reassembled. Somehow I forgot reinstall a very important part, the firing pin. I did a function check and what happened is the cam pin rotated and the bolt won't close. I can pull the bolt back and forth freely with the charging handle but the bolt won't close.

I've tried using a thin piece of wire to rotate the cam with no luck, as well as a small screwdriver. Nothing.

I can't separate the upper and the lower because the bolt is stuck back just far enough. Any suggestions other than take it to a smith or send it back to the factory?

Thanks

The bonehead award is all mine , most of the time
The cam pin is held kind of captive by the charging handle
You may be able to use a dental pick through the ejection port to tweak it around
Good luck with your new tough spot

Thanks from SA762

you can't get it out?

you might just have to do a complete strip of the upper

what i wound up doing is using one of those harbor freight type body pullers that i had in the garage,(1/4 20 threaded tip)went to ace hardware and got a 5 1/2 inch 1/4 20 bolt.put bolt in vise 1/2 inch or so sticking out,and beat the bolt head until approx 45 degrees. then took bench grinder and ground the bolt sides flat to the bolt shank,the upward bent tip, fit right into the carrier slot.popped stripped upper into barrel vise,3 shots with the slide hammer,popped apart.

need a vise with wood or a ar-15 barrel vise to hold the barrel

try mortaring it

FIXED!! Never ever do what I did! Upon closer inspection the bolt needed to rotated just alittle bit so the lugs would line up correctly with the chamber. A few taps with a punch and hammer and she went into battery. Thanks

Glad ya got it apart! We've all done something similar.

One of my favorites was a Pfc who brought me his M16A2 with a CHAMBER BRUSH lodged halfway down the barrel. I couldn't decide whether to be angry for his boneheadedness or admire his perseverance. Numerous whacks on the cleaning rod with a 3lb sledge fixed the problem.

Glad it's fixed - I've had a few "oh crap I'm boned" moments during home gunsmithing experiments but they usually work out with a bigger hammer or by sending a case of beer to the local pro smith.

Glad you got it worked out, but you can separate the upper from the lower with the bolt out of battery by just taking both the pivot and take down pin out at the same time.
