AR Bolt Carrier Groups

This category contains AR bolt carrier groups, which are a critical component of the AR platform, responsible for cycling the action and chambering a new round. These parts are typically used by builders and owners of AR rifles for target shooting, hunting, and self-defense, as well as for upgrading or replacing existing bolt carrier groups in their firearms.
When buying an AR bolt carrier group, shoppers should look for specific attributes such as the material construction, finish, and compatibility with their existing rifle configuration, as well as the carrier’s weight and gas key design. Additionally, considerations such as the bolt’s coating, the carrier’s machining, and the inclusion of a firing pin and cam pin are also important factors to compare when selecting a bolt carrier group.
