is it just a little dot in the center?
I think it is normal... my 5.56 AK does that to all the rounds that get chambered.. its not enough to make any serious dents or chances of setting it off... and if it did, that means i can possibly have a MG on my hands

It's normal ops.
The AR-15's have a "floating" firing pin. That means it is not held to the rear by a spring.
The only person I've met who had "slam fires" (weapon discharging when you chamber the first round) was a buddy doing his own reloading who wasn't seating his primers deep enough.
I've never had a problem with factory/issue ammo.

It's normal.
I believe I read of 1 slam fire that was sort of documented with a witness stating that the operator did chamber the round correctly.
It's been studied and the solution my unit came up with is to rotate the top round in the magazine.

This question is repeated over and over.
I still chuckle when a newer shooter starts playing with a Military Type semi auto
I think the manufacturers should put a notice in their manuals:
Warning, this weapon will dent the primers of cartridges that are hand cycled through the action and not fired.
It is normal, DO NOT be alarmed!
That is if anybody bothers to read the manuals.

Related question, are'nt there "harder" primers for reloading .223 for ARs?

All my semiautos do it, including those with firing pin springs.
Yup. that's the rationale for using slightly harder primer when loading for semi-automatic/full auto rifles.It help reduces the perpensity of an accidental discharge.
That's also part of the basis behind the use of aftermarket titanium firing pins that have less weight than the oem firing pins,which reduces the possibility of an accidental discharge.

It is normal. The only time I've heard of it being a problem is:
1) With reloads where the primer was set too high
2) Repeatedly (dozens of times) rechambering the same round over and over. I've read of two cases where this happened with Winchester 64gr Powerpoints in California and one case of it happening with M855 in Iraq. In all incidents, policy dictated a lot of unloading and loading as the weapon entered or exited "safe" areas and the same round was getting hit over and over and over.
Even then, those appear to be more freak incidents than anything; but if you have to load/reload the same ammo frequently, it probably doesn't hurt to rotate the top round of ammo on an AR15.
Except that in actual use the titanium pins seem to be more brittle and prone to piercing primers once the tip fractures into a sharp point.

Always point your weapon in a safe direction (such as a hippy or a communist).
Enough said!

And if neither of those are handy, I've seen picture-tube monitors/TVs successfully stop rounds up to 7.62x39 steel core from very short range.

shooting people?
Ok, I'm brand new here. As a lurker w/o a profile for a while, I've found some very helpful information about firearms, but thought it'd be good to join up. My intent is not to ruffle too many feathers here, but I have a question: the forum guidlines state that this is a family friendly site, and I'm wondering if making jokes about shooting people (i.e. hippies) qualifies as being "family friendly".

Thanks for the welcome. Ok, Strat81, I guess you're right, there is a lot more objectionable stuff out there....I'll just roll with it.
Moving on back to the primer question. I've used CCI primers in my .223 bolt action reloads with good success. I'm shopping around for an autoloader .223 and expect I'll be loading for that too. Any suggestions for preferred "slightly harder" primers for autoloaders?

Thanks....out of stock, at Midway, anyway. Who would've thought that someone would be out of primers!?

The hippies and communist remark was a joke relax. I found it mildly amusing too btw as hippies and commies are the sworn enemy of your typical gunnie.
Denting primers is normal in an AR, every AR I have owned does this. As others have stated I would avoid chambering the same round over and over, as well as chamber it with the rifle pointing in a safe direction. The only time I have heard of this being a problem is on the very first AR's that had a heavier firing pin.

As of the time I looked, THR has 47,292 members. Some of these members will find those remarks not family friendly. Some will find THR a dry and humorless place that doesn't tolerate their all-in-good-fun boisterous remarks. Somewhere in the middle we try to draw a line.
As moderator in the Rifle forum, I can say that if you found that comment offensive, then you probably aren't going to care for the way I moderate the forum and should consider that in deciding where to read and post.
If you want to discuss whether that comment is appropriate for THR, the Technical Support forum is the place to have that discussion. If you want to discuss primer dimpling in ARs and other semi-autos, this is the thread.

Just think of that small dent on the primer as an unexpeted expanded feature of your rifle , it checks every time for a broken fireing pin . no dent , you have a dirty/broken bolt problem , a loud noise you have a fouling problem , anything betewen and your good .
