DPMS Panther Arms AR-10 OEM Nitride .308 Bolt Carrier Group

The DPMS Panther Arms AR-10 OEM Nitride .308 BCG is a factory-original Bolt Carrier Group purpose-built for the AR-10 platform. The bolt is machined from 9310 steel with extra-strength extractor springs and paired with an 8620 steel carrier; the entire assembly is treated with a nitride finish for improved wear resistance, lubricity, and corrosion protection over standard phosphate finishes.

Designed as a direct drop-in for mil-spec AR-10 pattern uppers chambered in .308 Winchester, this OEM BCG is the same unit found in DPMS factory rifles, making it a reliable choice for a new build, a worn-part replacement, or refreshing an existing platform with proven factory components. The nitride surface treatment reduces friction during the cycling stroke and helps the carrier shed carbon and fouling during extended range sessions.
