ErikW Posted October 31, 2006 Share Posted October 31, 2006 My AR-15 shorty won't go into battery. (After a few rounds of firing today.) Consequently, I can't break it open to remove the carrier and have a look at the bolt and cam, which is where I suspect the problem is. The carrier moves back and forth freely, but stops about .25" from in battery. The forward assist doesn't do the trick. The chamber is empty and the lockup area is as free of foreign matter as I can get it under the circumstances. How can I even get this thing apart to diagnose the problem? Remove the buffer tube and take the carrier out that way? Link to comment Share on other sites More sharing options...
Dan Sierpina Posted October 31, 2006 Share Posted October 31, 2006 (edited) Pulling both the front and rear pins doesn't work??? Is it possible you had a case separation, leaving the forward portion in the chamber? Edited October 31, 2006 by Dan Sierpina Link to comment Share on other sites More sharing options...
vikings501 Posted October 31, 2006 Share Posted October 31, 2006 Most likely, you have a bent charging handle, try pulling the handle back and try to straighten it. Link to comment Share on other sites More sharing options...
Bear1142 Posted October 31, 2006 Share Posted October 31, 2006 Erik, You may have a blown primer in the recess of your bolt cam pin (ask me how I know this.) I think if you pull both pins, you'll be able to get the upper off and pull it apart. Erik Link to comment Share on other sites More sharing options...
Patrick Sweeney Posted October 31, 2006 Share Posted October 31, 2006 Yea, push both pins out and ease the upper forward off the lower. There's a blown primer in there somewhere; barrel extension, charging handle channel, gas tube or carrier spigot, behind the bolt lugs on the off side, or in the cam pin hole. Let us know where, you may have found a new spot for primers to cause havoc. Link to comment Share on other sites More sharing options...
ErikW Posted October 31, 2006 Author Share Posted October 31, 2006 Of course, take it apart with both pins, what was I thinking? Of course, I was shooting Federal brass with primer pockets so loose I dabbed nail polish on them. But there was no primer. I used a cleaning pick on a suspicious spot in the barrel extension (locking lug recesses, whaddaya call that?) and that was it. A tiny piece of carbon or something. (Carbonized nail polish?) My AR-fu is weak after being away from 3 gun. Link to comment Share on other sites More sharing options...
Dan Sierpina Posted October 31, 2006 Share Posted October 31, 2006 Erik, You're joking about the nail polish to hold in the primers!! Aren't you???? If they're that loose, they're that easy to push out and put into good brass! Link to comment Share on other sites More sharing options...
ErikW Posted October 31, 2006 Author Share Posted October 31, 2006 No I'm serious. They weren't held in by it, it was just an added measure of security. A dab where the edges meet. I only use 1xF Federal brass for low-velocity plinking rounds and after firing I trash it. Link to comment Share on other sites More sharing options...
George Posted October 31, 2006 Share Posted October 31, 2006 A lot of the High Power folks at my local club do that with Federal brass too. Kind of in jest, I once asked a local Hi-Master if he thought the primer-piercing loads he uses at 6hunnert might have something to do with the loosey-goosey primer pockets after re-loading them a few times and he just smiled ;-) It is known that Fed brass has that tendency. I won't touch the stuff in an AR for this very reason. A spent primer floating around inside the action is no fun at all :-( Link to comment Share on other sites More sharing options...
