Will this upper “'Patriot Ordnance Factory P415 Complete Upper (Piston Driven Adj. Gas Block) 5.56x45mm NATO” fit on this Franklin Armory M4 lower? This will be my first “build”…what else will I need to complete this gun?

Hi Steve and welcome. Yes Sir it will no issue. Since the upper is complete with bolt and charging handle, nothing else will be needed. Cheers, stay safe and enjoy the build!
