I posted awhile ago asking opinions on parts I was planning on buying for my first AR build. Now comes some more specific questions. I finished my lower, and all that is left for my upper is the barrel and hand guard. I was planning on going with the Novesle Chrome Lined 16 barrel which of course is currently out of stock as well as the BCM KMR15 hand guard which again is currently out of stock. If you have either of these, is it worth waiting, and if not, please give me some options to look into. I want to stick with the 16in chrome lined barrel with a mid length gas system, as well as a 15in modular hand guard. Suggestions and opinions welcome, I'll even welcome criticism.
