Sons of Liberty and Christian Craighead Deliver the OB1 Signature Rifle—A Purpose-Built Collaboration

Sons of Liberty Gun Works teamed up with former British SAS operator Christian Craighead to develop the OB1 Signature Rifle—a purpose-built platform shaped by real-world experience and an uncompromising standard for performance. Every element of this rifle reflects a shared vision: to create a fighting rifle that balances modern capability with the proven fundamentals of durability, control, and reliability. Designed with input from one of the most respected figures in special operations, the OB1 stands as a reflection of what a professional-grade rifle should be when built without shortcuts.

This is the personal rifle of Christian Craighead—the British SAS legend who went global after his solo response during the 2019 Nairobi terror siege. Now based in Texas, Craighead partnered with Sons of Liberty Gun Works to bring his vision to life. The result? A duty-grade rifle that blends combat-readiness with refined craftsmanship, and the kind of specs you’d only trust if your life were riding on it.

Built to Fight. Styled to Remember.

From the first glance, the OB1 wears its heritage like a banner. The rifle wears Craighead’s modern take on Rhodesian Brushstroke camo, a nod to old-school jungle warfare with updated edge. Deep laser engraving of the Blackbeard Boarding Party insignia—his personal symbol—anchors the gun with maritime grit and Revolutionary War undertones. This isn’t just camouflage and branding—it’s a story told in steel and cerakote.
