Proof Research Elevation MTR .338 ARC 16" Stainless Carbine

The Proof Research Elevation MTR 338 ARC TFDE 16" barrel assembly delivers purpose-built precision for modern tactical and competitive shooting platforms. Engineered for shooters who demand accuracy without compromise, this stainless steel barrel is designed for AR-platform rifles chambered in the increasingly popular 338 ARC cartridge. Whether you're building a recce rifle, setting up a dedicated precision carbine, or upgrading an existing platform, this barrel provides the ballistic performance and durability required for demanding field conditions.

Manufactured from premium stainless steel, the Elevation MTR features Proof Research's proven design that balances thermal stability with lightweight handling—critical for extended shooting sessions where barrel heat can shift zero. The 16.5-inch length maximizes velocity for the 338 ARC cartridge while maintaining a compact, maneuverable profile suitable for short-to-mid-range engagements and tactical applications. The TFDE carbon fiber stock provides superior ergonomics and reduces overall system weight, allowing shooters to maintain control during rapid engagements while the stainless finish resists corrosion in harsh environments. This barrel arrives without integrated sights, enabling the end user to specify optics or backup iron sights that match their mission requirements.

Law enforcement tactical teams, military precision riflemen, and competitive shooters benefit most from this platform's accuracy potential and reliability in demanding conditions. The 338 ARC round offers superior ballistic performance over standard intermediate cartridges while maintaining AR-15 platform compatibility, making this barrel ideal for operators who need extended effective range without shifting to larger, heavier magnum systems. Installation requires professional gunsmithing for proper headspace verification and torque specifications; compatibility with most AR-pattern uppers and receivers is standard, though chamber reaming may be necessary for existing platforms.
