Hi all. I am building an AR and I want one that is not "off the shelf". I am looking for a free floating quad rail (either mid length or carbine) similar to the GG&G. There is nothing wrong with this one, I just want to know if there are any other options. The big thing is I want to be able to customize the rails (I like the option for offset rails). As slim as possible. And of course I like unique. I have also been looking at the Yankee Hill Diamond quad rail, though no option for offset rails. http://www.gggaz.com/index.php?id=44&parents=38,112 http://yankeehillmachine.com/store/product439.html I have tried searching here and on the web, but it is hard to explain in a couple keywords. Thanks everyone!!!
