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.

NEW FOR 2026 – The OB1 rifles have been updated to feature the P3 barrel from the MK1 rifle. Barrel options are now 11.5″ and 14.5″ in length.

Video about first version with 13.7″ barrel:

The OB1 rifle is deeply engraved with the Blackbeard Boarding Party logo (Craighead’s company).  The classic pirate flag imagery (with its roots in close combat) has been updated with some the weapons used during the Revolutionary War.

This rifle is Cerakoted with Craighead’s trademarked version of Rhodesian Brushstroke camouflage. (NOTE: Each rifle has a unique pattern and varies between each individual rifle)
