Those flametrowers are really good. I like the pieces you used for it. So, you want to yoin the Metal Legion. I'm glad to hear it. There is a group called Metal Legion Recruit Command.
http://mocpages.com/group.php/16812 Here is a link to it. It's a more active group than the original Metal Legion. If you joined to the MLRC you have look at the Garrison Commander Challenge thread
http://mocpages.com/group_conversation.php?id=16812&topicid=67443 There are two types of units in the ML. Garrisons based on mandalorian torsos and militias.If you don't have mando torsos, no problem, you still can build a militia squad. Welcome to the Metal Legion!
