Description
Upgrade your AR-15 with the Armaspec .223/5.56 Bolt Carrier Group — a Mil-Spec BCG built for longevity and consistent performance. The nitride surface treatment increases hardness and reduces friction so the carrier runs smoothly and resists wear; it’s also easier to clean and maintain than many untreated components. Machined to Mil-Spec dimensions, this BCG drops into any standard AR-15 upper and supports .223 Remington, 5.56 NATO, and .300 Blackout chambers with a purpose-built bolt and proper clearances.
A staked gas key prevents loosening under high round counts and ensures dependable gas alignment shot after shot. Whether you’re assembling a new build or replacing a worn carrier, the Armaspec nitride BCG offers a balance of durability, reliability, and ease of upkeep. Pick one up at AR-15 Discounts for a dependable upgrade to your AR platform.
