Faxon 338 ARC Enhanced Forged AR-15 Stripped Upper Receiver W/ Completion Set

Faxon Firearms^® 338 ARC Enhanced Forged AR-15 Stripped Upper Receiver w/ Completion Set

Precision-Built Forged Upper for the .338 ARC Platform

The Faxon Firearms^® 338 ARC Enhanced Forged Upper Receiver with Completion Set is purpose-engineered to deliver precision alignment, strength, and dependability for the powerful .338 ARC cartridge. Machined from high-grade 7075-T6 aluminum forgings, this enhanced upper maintains tight dimensional tolerances to ensure proper fit and function with .338 ARC and other large-frame AR-15 compatible components.

Enhanced Forging for Strength and Alignment

Faxon’s enhanced forging geometry improves rigidity around the ejection port and barrel extension while maintaining compatibility with standard AR-15 lower receivers. The result is a receiver that can manage the increased bolt thrust and chamber pressures of .338 ARC loads without excess weight. Each unit is hardcoat anodized Type III per MIL-A-8625 specifications for exceptional surface hardness and corrosion resistance.

Complete Set for Easy Assembly

This upper includes Faxon’s completion set—containing the forward assist assembly, ejection port cover, and associated hardware—allowing builders to streamline installation and finish their upper without sourcing additional small parts. Every component is selected to match Faxon’s quality standards, ensuring reliable performance and consistent alignment during assembly.
