Aero Precision APAR620201AC EPC-9 Threaded Receiver 9mm Luger 7075-T6 Black Anodized Aluminum for AR-Platform

The Aero Precision APAR620201AC EPC-9 Threaded Receiver in 9mm Luger is purpose-built for shooters and gunsmiths assembling compact, suppressor-ready AR-9 platforms. This upper receiver serves as the foundation for 9mm AR builds that demand reliability, precision engineering, and compatibility with threaded barrels and muzzle devices. Whether you're building a duty-grade PCC (pistol caliber carbine), home defense platform, or range-tested competition rig, this receiver delivers the dimensional accuracy and material integrity that distinguishes Aero Precision components in law enforcement and tactical circles.

Machined from 7075-T6 aluminum—the same alloy trusted in aerospace and military small arms—this threaded receiver maintains tight tolerances essential for reliable bolt carrier group function and feed consistency in 9mm platforms. The black anodized finish provides corrosion resistance and a professional appearance while reducing glint in low-light operations. The threaded designation indicates this receiver is optimized for barrels with integral or removable muzzle devices, enabling shooters to add compensators, suppressors, or brake systems without additional adapters. At 0.73 lbs, the receiver contributes minimal weight to your build, allowing you to balance point-of-aim speed with ergonomic handling—critical in tactical or defensive scenarios.

This EPC-9 receiver is ideal for law enforcement armorer builds, civilian tactical trainers, and home gunsmith operations requiring mil-spec compliance and proven field durability. Compatibility extends across standard AR-9 bolt carrier groups, magazines, and furniture, simplifying parts sourcing and maintenance in the field. Installation requires standard AR assembly tools and knowledge; the threaded interface ensures your chosen barrel and muzzle system seat securely with repeatable accuracy. Aero Precision's quality control and lifetime warranty underscore the manufacturer's confidence—a reassurance that matters when your platform must perform under stress.
