I think it comes down to a few things. Quality control, who, as MJ said, assembles it, and what you're planning on using it for.
My opinion is best summed up like this. The 1911 is made by dozens of companies. The specs for a 1911 haven't changed. But truth of the matter is, even though, technically, all are the same, the quality differences between the various brands can be extreme.
You can get the $300 special that will throw rounds down range just like the $1,500 ones can. But they are usually less accurate, and also more prone to FTE's and FTF's.
You have less expensive companies in the AR world, and 1911 world, that make solid, reliable equipment. You have high end companies that ride their reputation, but many have earned that reputation by de-bugging their firearms to the point you know you have something that is going to do what it is designed to do, every time, and you never get that nagging wonder in the back of your mind that 'what happens if I need it, and it fails?'
Research what you want it to do, question on this site, listen to those who know, which I count as MJkeat, AgentTikki, Dog, Fsted, just to name a few. You'll, after perusing this section of the forum, quickly learn who knows what they are talking about and who's just wasting pixels and trolling.
I am by no means an expert on the AR, as I'm building my first. But the above named are the ones I've found who provide solid information, and are willing to offer said advice, and guide you down the right path.
