WTB AR15 Barrel 16"

OK well what the hell might as well ask. Does anyone have a standard profile AR15 Barrel 16" in 1:9 or 1:8 twist, 5.56/223 chamber, prefer chrome or nitrided sitting around that they want to part with? I plan to put something together along the lines of an LMT service rifle.

Worth asking...
