One thing gun-owners enjoy most is tinkering, and the more accessories and aftermarket parts that are available, the better. In terms of modern tactical rifles, none is more popular than the AR, and naturally it has more manufacturers making more accessories and improvements to tack on it. Still, creating a custom look for your AR, while not difficult, can stretch the mechanical abilities of some and the wallets of most. That said, there has been a growing market for factory rifles that go direct to the consumer with the more popular bells and whistles already installed.
