Sons of Liberty Gun Works East India Starter Kit, Upper Receiver, 5.56 NATO, 16″ Threaded Barrel, Black

Product Description

The Sons of Liberty East India 5.56 upper receiver is a purpose-built assembled upper designed for AR-15 platforms seeking reliable caliber conversion and multi-platform versatility. This starter kit delivers a 5.56 NATO chambered upper with a 16″ threaded barrel and matte black finish. Additionally, the threaded barrel accepts standard muzzle devices, giving you the flexibility to customize your setup for training or duty use.

Built on the AR platform, this upper receiver integrates seamlessly with standard AR-15 lower receivers. The assembled construction means you get a complete, ready-to-mount upper out of the box. Furthermore, the 1/2×28 thread pitch on the barrel ensures compatibility with common muzzle device options across the 5.56 platform.

Ideal for Caliber Conversion and Training

Whether you’re building a second rifle, setting up a dedicated training platform, or converting an existing build, the Sons of Liberty East India upper delivers dependable performance. The 16″ barrel length balances velocity and handling, making it suitable for both close-quarters and distance work. Moreover, pairing this upper with a 9mm or other caliber lower receiver opens multi-platform options without requiring a complete firearm purchase.

Note that this upper receiver does not include a bolt carrier group, charging handle, or muzzle device, allowing you to select components that match your specific needs and budget. The matte black finish resists corrosion while maintaining a professional appearance. Finally, Sons of Liberty Gun Works’ reputation for quality machining ensures reliable function across high-volume training sessions.
