This billet upper AR-15 receiver from Yankee Hill Machine is ready to build into a great modern sporting rifle. It has a stylized look that's just a little different and doesn't exactly look like every other AR on the planet, which was the mindset that led to Yankee Hill's MODEL-57 rifle. It us precision machined from 7075-T6 aluminum and will match any mil-spec lower receiver.
