Well RM, as far as I can tell, you would be the first to attempt it.

Unlike blasters such as the StrongArm, the Mastodon has a rigidly fixed cylinder (aka drum). It more closely resembles the Rotofuy as far as the cylinder mount points are concerned. I've looked mine over, and it would require new mechanicals as well as shell work to make it practical.

Far be it from me to be a naysayer, but I just don't think it's worth it. First of all, it's only really advantageous if you have a spare drum to pop in. Otherwise you're just talking about the difference in the reload time, which seems negligible IMHO. Seems like a lot of work for little return.

This is the best mod I've seen so far for the Mastodon. I know he's using 180s, but I'm sure this could be done with 130 Rhinos if you wanted to take a shortcut.
