This Russian man videoed himself shooting a TOZ-106. It is a short barreled shotgun with an underfolding stock that is bolt action and magazine fed.
He shoots it and has a fail to fire. He recharges the firing pin by actuating the bolt lever a couple of times. I must say I was wincing to see if he was going to open the chamber. Luckily he set the gun down in a safe direction and as he moves away the shell goes off.
UPDATE: Probably fake
