K'nex Chaingun's/MG's Ect.

attention to all people who have ben in Knex war's (any one else as well) do you find chaingun's effective?,is the rapid fire worth the loading time?, I just made a M249/Nerf Vulcan looking thing and I took apart my AK-47 and I want to know if it was worth it.

*Question to Knexers would you rather have a very effective non jamming MG,or a reliable single shot mag fed gun in to battle with?*
