Sons of Liberty OB1 Craighead Signature 11.5" 5.56 Pistol

The Sons of Liberty Gun Works OB1 Craighead Signature 5.56 pistol delivers Christian Craighead’s specified fighting setup in an 11.5-inch pistol configuration, available now at Battlehawk Armory. Built around an 11.5-inch P3 chrome-lined barrel with a carbine-length gas system, this OB1 uses forged 7075-T6 receivers and a 10.75-inch L89 M-LOK handguard with a titanium barrel nut. Each pistol is finished in Craighead’s trademarked Rhodesian Brushstroke Cerakote, with a unique pattern on every gun, and the lower is engraved with the Blackbeard Boarding Party logo.

The pistol configuration pairs the compact 11.5-inch barrel with a HUXWRX flash hider, Liberty 2-stage trigger at approximately 4.5 pounds, ambidextrous Liberty charging handle, and Magpul K2+ grip and trigger guard. An intermediate-length buffer system, 7-sided M-LOK rail, and polymer ejection port cover complete the package. Updated for 2026 with the P3 barrel from the MK1 line, the OB1 is built as a complete 5.56 pistol ready to pair with a brace.
