Newbee with a possible dumb question. I am looking to buy a Colt Match Target M4 model 6400C. The lower says .223 Cal. Can I still shoot 5.56 ammo with it?

Your 6400C comes with a 5.56-chambered, fully-chrome-lined barrel.

I have the MT6400c, I thought only the chamber was chrome. I had the stamp codes, I can't find them now but the C stamped on the barrel meant chromed chamber, MP means magnetic particle tested. C and another letter meant chromed lined barrel. Correct me if I'm wrong because I hope I am because I would like to have a chromed lined barrel on my Colt. On a short note , I like it a lot. Theres no disappointment with it at all. I have about 5 k rounds through it using Labelle mags and genuine Colt mags and not a problem with those.
