My contract with Military Times prevents me from copying the information from one site to the other. Hit the link below for more information, pictures, and the writeup. The condensed version can be found below.

I get a few email/ IM/ PM a week regarding rails. Free float vs non, long rails, cheap rails, cut out FSB, anti-rotation, etc etc.. Instead of writing out a short version each time, I decided to write something out that is a bit more lengthy.

Please don't look to this article to give you names, or tell you what you have to go buy. Its a list of question you may or may not have thought of, and hopefully the answers presented will hep you out.

Its a long article, but it should help some people out.
