AR-15 Glitch

[Ganderite]

Today my AR-15 had intermittent trigger failures. Could not figure out what was wrong.

Brought it home and put a bright light into the trigger well and spotted a primer hiding under the trigger. This was causing the problem. Would it be a good idea to drill a 1/4" hole at the bottom of the trigger well so crap would fall out?

No! More crap will get in then you will let out!

You could drill, tap, and put a plug in such a hole.

I'd be willing to make a bet that either you were shooting reloads... or 5.56 in a rifle chambered for 223

Nork CJ95 ammo?

Stop shooting Norinco ammo, problem solved

I've had the same issue as well. It happened to me when using reloads and having loose primer pockets. The primer comes out either before firing or after and gets lodged somewhere in the trigger assembly. This usually happens in the middle of a competion and causes you to loose the match. Been there...done that... For us shooters on a one-way range, drilling a hole or slot in the bottom would work just fine IMHO and make it a lot easier to get that pesky primer out. Or make sure that you throw those cases out that have loose primer pockets.

I would advise against it, I would suspect the odds of having a primer failure that way are a lot lower than drilling a hole would be justified for. Fluke issue, don't worry about it.

Absolutely a non issue.

Some guys have had primers pierce or pop out on their surplus CJ95 Norc ammo.

And I'd be willing to bet you haven't got a fricken clue what you are talking about. How on earth could 556 in 223 cause the primers to fall out of the cases?

 

[pb_blade]

Someone once said 5.56 and .223 were interchangeable until the internet came around.....

I second this, my thoughts exactly.

On another note, I have no idea but, I'd take into consideration that there might be a legal grey area that modding your lower near the trigger group might be verboten, even if it is only a drain hole. Something to think about.

Your "I have no idea" statement is bang on the money.

People fill in the area to prevent trigger issues with primers. Another alternative

 

[Dietz]

Nobody should put a drill bit or a file, or any metal removing tool for that matter, to ANY AR-15 to make it work, that's never, none.


My god, the amount of absurdity in the black rifle forum is amazing.

I'd be willing to bet that you don't know what you're taking about there either...

"So there you are on a hot summer day, shooting your supply of real-deal 5.56-spec ammo through your .223-chambered rifle. The summer sun beats down and pressures rise. Black rifles left in the sun can easily reach 140 degrees even before they’re fired. Add to that the temperature increases from shooting, and you have some real heat problems coming on. Let’s make it worse: the particular lot of your 5.56 ammo is at the top of the allowed pressure and at the bottom of the allowed brass hardness. The ammo maker tested it in a 5.56-chambered test barrel and, while it was in the top end of the allowed specs, it is within the safety margin.You’re having a blast, when all of a sudden your rifle stops working. What happened? Well, the heat increased the already maximum-made-excessive pressure and, on extracting a fired case, the pressure had expanded the case enough for a primer to fall out of the primer pocket and into your rifle. Actually, it probably has been losing primers for the last couple of magazines—pick up and inspect all your brass. You’ll see you’ve been losing ne or two primers per magazine. But it wasn’t until one fell into your action and tied things up that you noticed."

Dude... I know EXACTLY what I'm talking about

I have personally witnessed it a few times...

Too tight a commercial spec 223 chamber - too hot 5.56 ammo. It happens enough that there is a reamer just to stop it! http://www.m-guns.com/tools.php > 5.56 Reamer

Nice try though... no cookie for you!

Same thing happened to me this summer. Primers got in the trigger group. I detached lower receiver from upper, tilted it upside down and all of 5 -6 primers fell out. Had no other problems and continued shooting after. often happens when using too many times reloaded brass.

I've never heard of this problem until today. I've been shooting my AR for 5 years and prior to that was in the CF Reserves and it never happened once to anyone. The next time it happens you guys need to buy a lotto ticket on your way home
