ZEV AR-15 Forged Aluminum Upper Receiver, Stripped

The ZEV AR-15 Forged Aluminum Upper Receiver (brand part no. UR-556-FOR) starts as a high-quality 7075-T6 aluminum forging before ZEV machines it to better than mil-spec dimensions, held to plus-or-minus .001-inch tolerances. That level of precision gives maximum compatibility with both mil-spec and aftermarket AR-15 parts and accessories, so it drops into a custom build without unexpected fitment issues. It ships stripped, ready for the barrel, bolt carrier group, and furniture of your choice. Forged rather than billet, it is built for the strength and versatility a shooter wants when configuring an AR-15 exactly the way they want it.
