.300 BLK Briefcase “Hitman” Gun (sorry for the historically bad timing)
This video details the construction of a unique .300 Blackout briefcase firearm, presented by an expert hobbyist and custom builder. Key components include a 4.75-inch KAK barrel, a 3D-printed lower receiver, and a manual straight-pull bolt action, all housed within a Halliburton Zero case. The build emphasizes compatibility with subsonic ammunition and suppressors for discreet use.
