The PVC in the picture can't be a potato gun. They need a larger chamber behind the barrel for either hair spray or compressed air. This looks more like storage

The PVC in the picture can't be a potato gun. They need a larger chamber behind the barrel for either hair spray or compressed air. This looks more like storage container to keep stuff dry from moisture in the soil. Not only that the police claim it was a firearm because they found an old round of ammunition in the dirt. That pipe in the picture has 43 mm stamped on it for diameter. No small arm ammunition could even use that as a barrel. The only thing would fit in 43 mm tube would grenades, mortars, cannon or artillery shells. This guy should not be in jail for firearm offenses and he really needs a better lawyer. The police are just being stupid here or just trying to save face.
