I am very new to black rifles, but have been bitten by the bug. I realize that this is a very difficult question because there are so many different types, parts, mods, accessories, etc. that the range can be quite large. What I am looking for is an entry, novice level AR that is either used, or just some lower end "brand" that is quite functional, but maybe not something that you are paying for the name alone. I'd like to find either a built AR with the basic parts or a kit of some sort that will allow me to build my first AR "project". I don't have the money to trick one out right now. This may seem very vague, but again, I am brand new to the AR world. I don't even really know where to start. I appreciate everyone's help!
