I have been thinking about building my first gun. I've assembled lowers and mated them with purchased uppers in the past. Over the holidays i picked up some tools and was thinking about attempting my first upper build. Was first going to do a 16" middie, but I am now thinking about going for the gusto and building a 308 from the ground up. Anything, aside from the increased component cost that I need to worry about? I am assuming the assembly process is the same, same torques and so on...

Thanks.
