AR-15 Glitch

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!

So you are saying you have been seeing the primers fall out of milspec 5.56x45 regularly?
What make? LC? RG? ADI? FN? Ruag? IVI???

I know of no military 5.56 made ammunition, NATO or otherwise, that does not have the primers crimped in.
I could (and have) seen this with hand loads using brass with stretched pockets and hand loads that are too hot of a load in general - but that doesn't fit with your theory of 5.56 in a .223 chamber...tell us all how that works again?
 
I have noticed this issue poping up more on some American forums and they can not have Chinese ammo so I think it has to do with the chamber or reloads/cheap ammo
 
Military primers are crimped and thus, this problem is very rarely seen with military ammo.

Ammo loaded (or reloaded) to 'Nato/military' pressures can pop primers when shot in a .223 chamber if there is no crimp.

Even .223 ammo (in a .223 chamber) that is on the hotter-end can present this problem.

Obviously, if you are experiencing this problem, you should back off your load (if you're reloading) or if it's factory ammo, consider using a different brand.

Fixed it for you.
In fact, I challenge anyone to site one example of a round with a properly crimped primer where that primer has popped out from back pressure on firing.
It is far more likely to see a convexed firing pin strike or a hole blown. Through the firing pin strike than a blown primer.

Seriously?

You disagreed with 'very rarely' and replaced it with 'almost never' :rolleyes:

Unlikely. Because it 'very rarely' happens. ;)

p.s. fixed it for you

Thanks for the spelling fix :redface:
I say 'almost never' because I'm not 100% certain, but I think 'never' is more appropriate.;)

I'll never understand why as soon as something jacks up someone's rifle, their first idea is to drill/dremel/cut something...

Because it's cheaper to do that than just run higher quality ammo and easier than it is to remove the lower, turn it upside down and shake it.

Society is training us to find a quick easy band-aid to everything rather than just fix the problem properly, which in this case is to stop running the cheapest ammo available and expecting anything but problems.
Yes I know there are plenty of people who have had no issues that are going to want to flame me so go ahead, but if you go through the threads there are also a lot of people that have had plenty of problems running Norc ammo and to me it isn't worth risking getting one of the bad cases. I'll stick to my American Eagle or better ammo or my handloads.

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

http://www.gundigest.com/223-vs-5-56/3

"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."

If you had any idea who Suputin is, what he knows, and what he's done with regards to firearms in general, you'd quickly retract your ignorant statement. You clearly, very clearly haven't a clue who he is nor do you have a clue about what you "cut and paste" from the internet.

223 in a 5.56 but not 5.56 in a 223.

And, no its not. I've fired both in both chambers more times than I care to count and many more have done the same(as in many thousands more), it works just fine.

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.[/QUOTE]

Ganderite, if it's your NEA rifle, drilling a hole would probably negate the lifetime warranty.

Completely agree with the first part of your comment. Weird eh, This is the second time I've agree'd with you recently ;)

I know you can use them interchangeably but prob shouldn't put 5.56 though .223. http://www.canadiangunnutz.com/foru...s-5-56-x-45-mm-NATO-is-it-safe-to-interchange.
