I’m surprised a military contractor hasn’t hired him

The military already has stuff much better with the bugs worked out designed by real experts with a blank check. You can bet on that. A gun duct-taped to an off the shelf drone is laughably amateurish to them.

SpaceBar is correct. These already exist in .338 caliber.

“Mounted onto this UAV is a lightweight gun turret developed by Space Dynamics Laboratory. The turret carries a .338 Lapua Magnum rifle and a situational awareness camera plus a scope with cameras attached that provides two levels of zoom. Control of the rifle is via a laptop computer with a Xbox 360 gaming controller used for aiming and firing.’
