New question all together. Does the length of a free float quad rail matter on a 16" barrel? I want a longer set up than normal but obviously not extending past the muzzle. Also can an upper be assembled without the use of a vise? I don't have one but would like to build my upper or watch somebody do it so I can get an understanding of how it goes together but I don't wanna pay someone an arm and a leg to do it either.

Bring your parts down to us at USDS and I can walk you through the process, we can build it here and show you exactly how it goes together.
