Note: if you have any spare Marvel Legends Iron Man hand reactor pulse blasts* laying about, they fit perfectly in the Heavy Infantry Mandalorian’s jet pack. (They also fit in his flamethrower barrel on his gauntlet but fix more loosely.) It’s a shame the figure didn’t come with them in the first place, but here is the next best thing if you are a multi-line collector like myself.

*These are from the recent Marvel Legends Invincible Iron Man which I purchased from DorksideToys.
