Now that I've built 5 ak's and there is really not much difference in ak & ar prices, I'm looking into building my first ar-15. My main question is should I get a chrome lined barrel and chamber or not? It only costs $50 extra from akpartskits, but really I don't know how nessesary it is. All of my ak's have chrome lined barrels and for good reason, but ar's and ak's generally eat different grades of ammo. What's the general consensous on this subject?
