OK then. Show me ONE. Just one... All these ads referred to surplus equipment. There was tons of it. I don't believe the police took bayonets with the guns. Most of these guns had been altered after police use. Bayonet studs cut off, muzzle boss removed, entire heat shield removed...they just needed shotguns.
Don't know where you got the idea he has a no US marked bayonet. That wasn't included in his description.
