>>42603566There was once a gun called the Fox Carbine. It lasted about as long as the Gyrojet. Same era, for that matter. Anyhow, it was intended for the LE market. One of the accessories available was a panzerfaust-style shield that hung mostly off the right side of the gun. The purpose was to give right side protection to LEOs who were prone behind cover and shooting from behind the right side of said cover. Iirc, said shield weighed somewhere around 8 pounds. The other big accessory was a cattle prod bayonet attachment, for crowd control. It was wired to a belt mounted battery pack, iirc a couple of 6 volt lantern batteries. But wait, there’s more! The cattle prod bayonet had a hacksaw blade imbedded in the underside, so if anybody tried grabbing it they’d get a lacerated hand for their trouble.
