A fair number of people seem to be recommending ammo with crimped primers through an AR-15 to prevent them from backing out. Is this a worthwhile feature to look for when shopping for AR ammo? The Federal American Eagle AR223 I bought has crimped primers, and apparently Federal uses slightly harder primers in the AR223 to prevent slam fires.

What's the consensus in the AR community? If I can find ammo with, and without crimped primers for the same price, which would you recommend? I don't see myself ever reloading 223, so that's not really a consideration.

Thanks!
 
I've never shot crimped primers through any of my AR's and I've never once had any issues relating to primers backing out.
If you're not reloading, I'd say it's whatever is cheaper. I would personally never pay extra just for crimped primers.
 
Just stop and ask yourself why anyone might "need" crimped primers...
What does a primer crimp do? (rhetorical question)
Under what conditions would that help you? (again rhetorical question)

If under standard conditions a primer crimp is not needed why would it be required for some other porpose?

Answer is mud, water and debris... Fire off a standard round in a clean gun and the round is safe to fire...

Fire that same round while the rifle is still dripping from the water you were just scuba diving in and some water is still in the barrel and chamber and suddenly you have an over pressure round. A crimped primer will keep the case from dumping the primer into your action and taking you out of the fight.

So unless you are going into battle or firing your rifle under wartime conditions, I'm thinking you are ok with the standard stuff.

The rifle you fire the round from is not relevant to this point.
