Sons of Liberty Gun Works AR-15 Stripped Upper Receiver – Mil-Spec AR-15 Lower

The Sons of Liberty Gun Works AR-15 Stripped Upper Receiver is a mil-spec forged upper designed for standard AR-15 lower receivers chambered in 5.56 NATO or .223 Remington. This is a blank canvas for custom builds, accepting any mil-spec bolt carrier group, charging handle, handguard, and barrel assembly. The M4 feed ramps are properly cut for reliable feeding with modern ammunition.

Forged from 7075-T6 aluminum and finished in Type III hard coat anodizing, this upper offers the durability expected from a quality receiver. The T-marks on the top rail provide reference points for optic and accessory mounting. Ships as a stripped receiver only—no port door, forward assist, or other components included. Standard installation using AR-15 upper assembly tools and techniques.
