This show is pretty good. They take a certain weapon and modify it or do restoration work on old pieces. As for what FilmMan wrote, this is a show for ENTERTAINMENT purposes. This show in NOT a history lesson. As much as I love learning about the history of weapons and military operations, sometimes you just want to watch someone mod an Ak-47 and fire it.
And if you have no idea and need to know the purpose of a suppressed shotgun (really?) then this show is not for you. Again, this show is for ENTERTAINMENT purposes if you want to learn more about a certain weapon and it's history go watch another show or look it up. But if you want to watch a weapon being modified and watch them blow stuff up with it, then you will love this show.
You kind of need to know a bit about weapons and enjoy them to enjoy this show. And by the way the M203 (Or clone) that they attached to the AR-15 which is the same thing as it's military twin the M-16 except it is only Semi-Auto, is NOT A FLARE LAUNCHER!!! They only used flare charges instead of the usual 40mm Grenades for obvious reasons. So FilmMan, I believe you aren't as familiarized with firearms as you say you are. And remember this show is for ENTERTAINMENT purposes.
Awesome show too!
