Rise Armament Complete Bolt Carrier Group 223 556 Black Nitride Finish RA 1011 BLK UPC 851046006033
Product Description
The Rise Armament Complete Bolt Carrier Group in Black Nitride (RA-1011-BLK) is a high-performance, precision-machined core component engineered for ultimate reliability in AR-15 platforms chambered in 5.56 NATO, .223 Remington, and 300 AAC Blackout. Built to exceed standard Mil-Spec tolerances, this premium BCG delivers exceptionally smooth cycling, lowered friction, and enhanced corrosion resistance under rapid firing schedules.
The carrier body is CNC-machined from 8620 tool steel, paired with a bolt precision-machined from Carpenter 158 steel that is individually High-Pressure Tested (HPT) and Magnetic Particle Inspected (MPI) to guarantee zero microscopic material defects. Both carrier and bolt are treated with an advanced QPQ Black Nitride finish, creating a slick, ultra-hard surface that sheds carbon, simplifies field maintenance, and drastically reduces lubricant requirements.
Complete with a properly staked gas key utilizing Grade 8 fasteners, a hardened tool steel extractor with an O-ring insert, and a shot-peened bolt face, the Rise Armament RA-1011-BLK bolt carrier group provides reliable gas sealing, smooth extraction, and drop-in durability for duty rifles, tactical builds, and competition setups.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Direct drop-in fitment for standard AR-15 / M4 / M16 upper receivers chambered in 5.56 NATO, .223 Remington, .300 AAC Blackout, and .350 Legend. Full-auto profile adds beneficial rear mass for reliable cycling across various gas system lengths.
- Ensure the host upper receiver is completely clear, magazine removed, and chamber visually and physically verified empty.
- Apply a light coat of high-quality synthetic gun oil to the carrier slide rails, cam pin, bolt rings, and gas key interior.
- Ensure the bolt is pulled forward in the extended position, align the gas key with the upper receiver charging handle slot, and slide the assembly home into the upper.
- Close the upper/lower receiver takedown pins, perform a manual charging check, and verify proper mechanical lockup and firing pin protrusion before staging.
