The Radical Firearms RF-15 forged AR-15 stripped lower receiver (brand part no. RF00966) is a black-anodized foundation for a custom AR-15 build chambered in 223 Remington/5.56 NATO. Radical Firearms built its name supplying affordable, reliable AR-pattern components to builders across the country, and this stripped lower keeps that value-focused approach in a receiver ready for a standard parts kit and buffer tube. Selling it stripped keeps costs down and lets the builder choose their own trigger, safety, and buffer system. It’s a solid starting point for a budget-conscious build that doesn’t cut corners on fit.
