Product Description

The SOLGW M4 Rebellious Stripes Complete Lower Receiver brings Sons of Liberty Gun Works’ reputation for hard-use reliability into a fully assembled foundation for your next build. Machined from 7075-T6 forged aluminum and finished with MIL-A-8625F Type III hardcoat anodizing, this lower is built to endure demanding use—whether it’s destined for a duty rifle, defensive carbine, or high-round-count training platform.

At the heart of the lower is SOLGW’s Liberty Fighting Trigger, designed to deliver a smooth and consistent pull that balances precision with speed. A 90-degree Quick Safety Selector allows for fast, positive manipulation, while the B5 Systems grip offers an ergonomic interface and secure handling. The distinctive Rebellious Stripes roll mark gives the receiver a recognizable SOLGW aesthetic while maintaining its professional, mission-focused design.

This lower is assembled to SOLGW’s exacting standards and includes a properly staked castle nut, an M16 auto pocket cut, and a complete carbine-length buffer system with an H-buffer for dependable operation. The result is a premium lower receiver that’s ready to run while still leaving room for users to customize other components as they see fit.
