Redfield EBT-LK 16" 5.56x45mm NATO AR-15 Complete Upper Kit

The Redfield EBT-LK (Everything But The Lower) kit, manufactured by San Tan Tactical, delivers every major component required to assemble a working AR-15 build — minus the serialized lower receiver, the flash hider or muzzle brake, and the trigger group. This EBT-LK configuration pairs a 16-inch barrel chambered in 5.56x45mm NATO with a complete upper receiver assembly and the supporting small parts needed to finish a mil-spec rifle.

Built around a matte black upper assembly, the kit ships with everything required to drop onto a standard AR-15 lower receiver. The serialized lower, the muzzle device, and the trigger are intentionally omitted so the builder can finish the rifle with their preferred components.

Items included in the EBTL kit:

• Complete upper receiver assembly with 16" 5.56x45mm NATO barrel
• Required small parts for assembly
• Supporting build accessories

Items not included (must be sourced separately):

• Lower receiver (serialized firearm component)
• Flash hider or muzzle brake
• Trigger group
