This Knights Armament Company 3.2 bolt assembly is a service-grade bolt carrier group component engineered for SR-15 and compatible AR-pattern rifle platforms chambered in 5.56 NATO/.223 Remington. Built with durability and reliability in mind, the 3.2 bolt features dual ejectors to promote positive extraction and ejection under a wide range of conditions, supporting consistent performance during extended firing.

Knights Armament bolt assemblies are machined from high strength materials and heat treated to withstand the stresses of frequent use and harsh environments. The bolt surfaces are treated to resist corrosion and wear, and the tolerances are controlled to maintain proper lockup and timing with compatible gas systems. This assembly is intended for direct integration into SR-15 pattern upper receivers or other AR-pattern platforms accepting SR-15 spec bolt carrier groups.
