Availability: In Stock
The Rise Armament RA1012BLK is a black nitride steel bolt carrier group purpose-built for AR-10 platforms chambered in .30 caliber. If you're assembling or upgrading a large-frame rifle and want a BCG that handles the demands of .308 Winchester or similar .30 cal rounds, this is a no-nonsense upgrade that focuses on reliable feeding, extraction, and consistent lockup. The black nitride finish resists corrosion and wear, making it practical for shooters who run their guns hard—whether that's long-range hunting, precision rifle competition, or regular range time.
Rise Armament engineered this BCG with the expectation that it will cycle cleanly and consistently. The black nitride treatment protects against rust and fouling buildup, so you'll spend less time cleaning and more time shooting. That durability matters when you're investing in a quality upper receiver and barrel; the bolt carrier group is the engine of your rifle, and cheap components invite malfunctions. A solid BCG pairs with good ammunition and proper maintenance to keep your AR-10 running dependably.
This is a straightforward, functional component—no marketing fluff, just a purpose-built part for shooters who expect their gear to work. Whether you're building a new rifle or refreshing an existing one, the RA1012BLK fits into an AR-10 lower and upper designed for .30 caliber rounds, giving you a proven foundation for accuracy and reliability.

The RA1012BLK is designed for standard AR-10 platforms in .30 caliber. It will work with any AR-10 upper and lower receiver assembly that accepts .308 Winchester or similar .30 cal rounds. Always verify your specific rifle's compatibility with your builder or manufacturer before purchasing.
This bolt carrier group is engineered for .30 caliber rounds, including .308 Winchester. Compatibility with other calibers should be confirmed with Rise Armament or your gunsmith.
Black nitride is a heat-treatment finish that hardens the steel surface, protecting against rust, corrosion, and wear from repeated firing cycles. It also resists fouling buildup and requires less maintenance than bare steel.
The bolt carrier group is one component of a complete rifle system. You'll need a compatible AR-10 upper receiver, lower receiver, barrel, and other components. Consult your build guide or a qualified gunsmith to ensure all parts are compatible.
