The San Tan Tactical STT EBTLK-16-BLK Everything But The Lower AR-15 5.56x45mm NATO 16" Upper Receiver kit brings together factory-matched components in a single, organized package. Built on a 6061-T6 aircraft grade aluminum upper with MIL-A-8625 Type 2 anodize and an M-LOK handguard, this rifle-length 16" chrome moly vanadium barrel assembly is ready to pair with most mil-spec AR-15 lowers for a clean, reliable build.
This configuration is ideal for shooters who want a complete upper solution for range use, training, or general-purpose rifle builds without purchasing a full firearm. The included mil-spec bolt carrier group and charging handle simplify assembly while maintaining compatibility with standard AR-15 parts. San Tan Tactical’s attention to fit, finish, and component selection makes this upper a solid foundation for a dependable AR-15 project.
