I am beginning to purchase parts for my first AR build. I am wanting to build it capable of firing 5.56 or .223 rounds. I am going to install a quad rail with 16" chrome lined barrel, adjustable stock. Awaiting on my Spikes Tactical Lower, and Palmetto State Armory upper. Would a fixed front sight or gas block be more beneficial? Or is it a matter of preference?
