An AR-15 skeletonized bolt carrier group (BCG) is a lightweight, precision-machined BCG featuring cutouts to reduce weight and increase cycling speed. Designed for competition and fast-action shooting, it helps improve recoil management and reliability. The skeletonized BCG works with AR-15 upper receivers, compatible barrels (such as .223/5.56, 300 Blackout), charging handles, and lower receivers. It’s ideal for custom AR-15 builds focused on speed, performance, and reduced mass, while maintaining compatibility with standard AR-15 components.
