Must buy for hunting rifle build! - Faxon Firearms .308 Winchester Pencil Rifle Barrel

Finished this rifle in December last year and finally got a chance to test it in the field. Aero upper, lower, and hand guard vortex tactical 4-16 moa scope, lantac bcg, and the faxon 20” pencil 308 barrel. Shot it all summer getting sub moa groups at 100 yards with federal premium 168 grain sierra match king bullets. I dumped a whitetail buck at 322 yards Sunday morning and my cousin dropped a muley tonight at 477
