Oh, brother, not this guy again. I have seen this Amsdorf guy before on other forums. He always ends up getting banned by the moderators. Already you can see why.
Let's examine who we are dealing with here. He claims he has a bunker buried 150 feet underground ("15 stories") in Missouri. Here is one of his videos where he says that:
His whole schtick is to try and get people to look at his videos so he can get paid per click, apparently.
Personally, I do not know of anyone who has a bunker (or any other structure, for that matter) that is 15 stories underground, particularly in the State of Missouri. Think about it....
Anyway, I know this guy's Internet history, I have seen his multiple videos, that he trots out until everyone is sick of looking at them, and he has zero credibility as far as I am concerned.
Fair warning to the members here. You can tell from listening to his videos he knows very little about guns. Who says "rack a frame" - try rack a slide, Ace; and it is called a slide release; but hey, why bother with actually reading your owner's manual and maybe learning what the nomenclature is for your gun's operating mechanisms, when all you plan to do is rapid fire them and spray bullets all over the place? Nice tight group you put together there, gunslinger.
Don't waste your time, folks. I have seen this guy's tired act before, and it only gets worse from here. He gets banned from other forums and goes looking for a new one once he's bounced.
I bet he won't last very long here either.
