My dad has decided to get into the AR world after I ended up buying my Colt 6920 right before world went crazy. Anywho, my dad is thinking of stepping it up into the Daniel Defense or LaRue realm for his purchase. I would say he's got somewhere between $1800 and $2400 to work with depending on how rich he's feeling that day . So first off, what recommendations do you have in that price realm? My second question is the title of this thread. As I was doing some product research into the HK MR556A1, Daniel Defense ARs, and LaRue's ARs (which are in stock btw) I realized they do NOT have chrome barrels. As you are well aware the 6920 has a chrome lined barrel, which I understand to improve the life of the barrel and help prevent corrosion (not that I don't clean it frequently regardless). Is the chrome lined barrel necessary for a civilian market? My dad is not quite as good about cleaning his guns but still does it regularly. What are the pros and cons to having one and not having one? Wanna kill these ads? We can help!
