The NATO spec primers are much harder but I use standard small rifle primers in my reloads and they work just fine with no issues at all.
 
No such thing as "Assault rifle primers".

There are nato primers for semi auto guns. They have a harder cup then the others.

Another note AR does not mean assault rifle.

I've used a few thousand of those AR primers as well as the normal ones. There is no noticeable difference in performance, and I've never had an issue using the normal ones in any rifle I've shot them out of.
 
Federal seems to make a "Gold Medal" line of match-grade primers. They also made a special grade just for AR. You can see it's a 205-series primer for small rifle. How much better is it for .223 and how much is pure marketing ploy? No idea, I'd just use it as a regular small rifle primer.

I know as I have seen them. AR does not mean assault rifle plain and simple. AR means Armalite Rifle.

Ar spec would mean that the cup is harder like the nato spec primers.

It is recommended to use primers with a cup thickness of .025 to help prevent slam fires. The CCI No.41 primers are a CCI 450 primer and have a shorter anvil and requires a harder blow to set the primer off.

•Mil-spec sensitivity
•Initiator mix optimized for ball/spherical propellants
•Available in large (No.34) and small (No. 41) rifle
•Use the same data as CCI Magnum primers

Remington ran our American Lake City Army Ammunition Plant from 1941 until 1985 and used Remington 7 1/2 primers in all the 5.56 ammunition long before the CCI No.41 primer was invented. The slam fire problem with the M16 rifle during the testing phase was cured by lightening the firing pin. This problem only happened when loading a single round without the magazine in the rifle to slow down bolt velocity. The vast majority of slam fires are caused by high primers that are not seated properly.
