Product Overview

The Yankee Hill Machine AR-15 A3 stripped upper receiver is a domestic-made foundation for custom rifle builds. YHM machines these uppers entirely in-house from 7075-T6 forged aluminum, then hardens them with hardcoat anodize in matte black to military or better specifications. The result is a rugged, precision component that pairs with any mil-spec lower receiver and accepts standard AR upper parts—dust covers, forward assists, charging handles, and bolt carriers all drop in without modification.

A3 upper receivers feature M4-style feed ramps and T markings, the modern standard for reliable feeding across ammunition types and platforms. YHM applies a dry film lubricant inside the receiver before shipment, reducing initial assembly friction and protecting against corrosion during storage. Whether you're assembling a duty rifle, precision build, or specialty carbine, a YHM upper gives you a known-good starting point without the premium markup of pre-assembled receivers.

This is a stripped upper—it arrives without forward assist or dust cover, so you'll select those components to match your build spec and preferences. Builders favor this approach: you control every detail, avoid paying for parts you might swap out, and end up with exactly the rifle you envisioned. YHM's in-house manufacturing and domestic aluminum sourcing appeal to shooters who value traceable supply chains and consistent fit-and-function from known suppliers.
