Then you should build it from the ground up vs paying for parts you are not going to use. IMHO but whatever works for you works for me. After all you are not spending my money. Tweaking small parts here and there makes sense and everyone does it what does not make sense to me is things like rails. It is too easy to get a OEM style rifle or one with the rail you want on the upper of your choice to buy something like the Sport II and immediately modify it.
