Product Features

YHM is proud to offer our first Billet Upper Receiver. The stylization of the YHM-110-BILLET was directly related to the stylization of the Billet lower which we finished first. Because we were working with Billet 7075-T6 Aluminum it gave us the ability to really create an eye catching upper receiver.  After multiple prototypes we arrived at what you see today, something that didn't look like every other AR-15 on the planet. It was this mindset that inadvertently led us to the MODEL-57, and in turn this upper receiver.
