B.A.D. AR-308 Bolt Carrier Group | DPMS Pattern | Nitride

The Battle Arms Development AR-308 Bolt Carrier Group is a premium DPMS-pattern component engineered for reliability, strength, and smooth operation in .308 / 7.62×51 AR platforms. Built from high-grade materials and finished in durable Black Nitride, this BCG delivers consistent performance for duty rifles, precision builds, and LR-308–based configurations.

DPMS-Pattern Construction for 308 AR Systems

This carrier group is designed to run in DPMS/LR-308/SR-25 pattern rifles, offering excellent compatibility with the most common 308 AR upper and lower receiver designs. The carrier is machined from 8620 steel, while the bolt is crafted from 9310 steel and properly heat-treated, shot-peened, and MPI-tested to ensure strength and long-term durability—even under heavy use.

Enhanced Materials and Nitride Finish

The Black Nitride treatment provides a hard, corrosion-resistant surface that reduces friction and improves cleaning. A tool-steel extractor ensures positive extraction with a wide range of ammunition, while the full-mass carrier profile provides reliable cycling across suppressed and unsuppressed setups.
