Solgw Loyal 9 Stripped Lower

The Sons of Liberty Gun Works Loyal 9 Stripped Lower is a forged M4 lower receiver engineered for operators who demand precision and durability in the foundation of their rifle platform. Machined from military-spec 7075-T6 aluminum and finished with Type II hardcoat black anodizing, this stripped lower serves as the regulated firearm component in AR platform builds, providing a proven foundation for custom rifle configurations used across law enforcement, military training, and civilian marksmanship.

The receiver incorporates an M16 full-auto pocket cutout machined to specification, standard for mil-spec compatibility with a broad range of fire control components and upper assemblies. The low rear shelf design supports optic mounting and accessory integration common in tactical configurations. Sons of Liberty Gun Works fully machines away flash markings from the aluminum forging process, yielding a clean profile without cosmetic defects. The Loyal 9 roll mark and Safe-Semi-Auto selector markings are precisely applied, identifying the lower while meeting standard marking conventions. At 0.56 lbs and compact in profile, the receiver integrates into lightweight and ergonomic rifle builds without sacrificing structural integrity.

This SOLGW lower is specified for builders, gunsmiths, and end-users constructing AR-pattern rifles for duty use, competition, training, or precision shooting. The mil-spec design ensures compatibility with standard M4 upper assemblies and fire control kits, making it suitable for users who already possess or plan to source complementary components. The 7075-T6 aluminum and hardcoat anodize deliver corrosion resistance and dimensional stability across temperature and humidity variation—a practical advantage in field and storage conditions.
