The OB1 CQB Craighead Signature Rifle The OB1 Signature rifle by Christian Craighead has been built to Christian’s exact specifications. Christian Craighead served for 28 years in the British military, including as a senior and highly decorated member of the 22nd SAS (the British Army’s Special Mission Unit) tasked with covert reconnaissance, counter-terrorism, and hostage rescue. He rose to notoriety after single-handedly shifting the outcome during the terrorist siege in Nairobi Kenya in January of 2019. Craighead retired from service in 2020 and now calls the US home.
