Rise Armament RA-1011 BCG 5.56/.223 Black Nitride AR-15 Bolt Carrier

The Rise Armament RA-1011 Bolt Carrier Group delivers enhanced reliability and extended service life through precision manufacturing and advanced surface treatments. This complete BCG assembly features black nitride coating that reduces friction while increasing corrosion resistance compared to standard phosphate finishes.

What Makes This Different

The RA-1011 incorporates properly staked gas keys and precision-machined components that meet or exceed mil-spec tolerances. The black nitride finish penetrates the steel surface rather than simply coating it, creating a harder, more durable surface that maintains lubricity even under high round counts. Independent testing shows nitride-treated BCGs can run 30% longer between cleanings while maintaining consistent cycling.

Key Features

• Black nitride finish provides superior corrosion resistance and reduced friction
• Precision-machined from 8620 steel with proper heat treatment
• Properly staked gas key with grade 8 fasteners
• Shot-peened bolt for enhanced fatigue resistance
• Chrome-lined gas key interior for extended service life
• Compatible with all mil-spec AR-15 upper receivers
• Includes complete bolt, carrier, gas key, cam pin, and firing pin assembly

Field testing demonstrates consistent extraction and ejection across various ammunition weights from 55-grain to 77-grain projectiles. The nitride coating maintains its properties in temperature extremes from -40°F to 140°F, making it suitable for duty use, competitive shooting, and hunting applications. The enhanced surface hardness reduces bolt face wear while the self-lubricating properties minimize maintenance requirements during extended shooting sessions.

Technical Specs

• Caliber: 5.56x45mm NATO/.223 Remington
• Material: 8620 steel construction with black nitride finish
• Weight: Approximately 11.5 oz complete assembly
