Billy, I understand completely, glad you weren't offended. I didn't realize that you demanded the chrome lining in the 20". And yes, there is always some yahoo (like I did this time) who points out no AR-15 is milspec - we are all just talking about what parts there are to conform to specs where applicable. I think we all want the same thing - a rifle that conforms as close as possible to mil-spec design and dimensions, no cheesy out of spec manufacturing. Colt's odd parts aside, the quality is there and is a standard - that's why my first 2 rifles were a Colts. With the others, it's hit or miss as some mfg's are better than others. Some have problems, others have none, but Colt is pretty stable. That's why I usually buy Colt uppers - I can bank on what I will be getting for my money.
you know exactly what i'm talking about AK Mike. Thanks for the coly support Billy
