Well I'm onto my second build finally and I've decided on going with a 8.5" ss noveske barrel, stripped spikes lower, BCM bcg, stripped aero precision upper (or one of the other uppers I would be satisfied with when they come back into stock!), and spikes lpk. Not a full list of parts but that's the main parts I have/have decided on. I plan on running a kx3 on it, so one of my main questions is where to start on buffer weight? I was going to get a spikes heavy buffer and just go from there. I thought maybe someone had this setup already and could provide some insight. Thanks for the help everybody.
