Hello,
I recently bought my first AR-15.  I would like to know how I can tell what kind of barrel it has. I know it is 16", but I wanted to know if it is a chrome barrel. It is an Olympic CAR-15 and I have read that you can shoot 5.56 but have to be careful with some rifles that are .223 specific.  Does a chrome barrel handle a higher rate of fire per minute?  This is the link to the rifle.

Your Olympic barrel is going to be good to go with 5.56 ammo. Oly is not the highest quality brand over the years.  But I think thier barrels are always good.  As far as that goes anything Oly that is good - is good.  The bad ones showed problems in short order.

AS for chrome lined, I don't know, perhaps a call to them would be best since no one else has chimed in.  I have bought thier reversable safeties (which are more nicely made then the standard ambi)   I found thier phone guys to be very good.

..And welsome to the forum.  Always wear your thick skin while here.

Just did some reserach on the Olympic site and it states that it is marked on the barrel along with the caliber.  Thanks for your input.

That barrel is most likely stainless steel. I'm not aware of a chrome lined Oly barrel. It'll be stamped on the top of the barrel just forward of the FSB.

Oly does not chrome line their barrels.  A number of years ago it was offered as a $40 option, but as far as I know they haven't offered that in quite a while.
