TRIARC Systems Mil-Spec AR15 Bolt Carrier Group – 5.56 / 300 BLK – NP3 Coated

TRIARC Systems Mil-Spec AR15 Bolt Carrier Group – 5.56 / 300 BLK – NP3 Coated

What truly sets this BCG apart is its premium NP3 coating — a high-performance nickel/PTFE finish that delivers exceptional lubricity, corrosion resistance, and wear protection. The self-lubricating surface dramatically reduces friction, minimizes carbon buildup, and simplifies cleaning, allowing shooters to run their rifles longer with less maintenance and reduced lubrication requirements.

Enhanced reliability continues with a billet 4140 steel extractor and upgraded Sprinco cryogenically treated 5-coil extractor spring, designed to improve extraction consistency under adverse conditions and high-volume fire. Combined with hardened internal components and a smooth satin gray non-reflective finish, the TRIARC NP3 BCG is built for duty rifles, suppressed setups, precision carbines, and professional-grade AR platforms.
