Sounds like something an iron hand/Raven guard/iron warrior would have

just some random shit I had hanging around that looked good on him! looks like like jump back mixed with smoker bombs mixed with a bolter... not really seen much like it imo

I'd say paint him up! Not sure what's attached to his shoulders but that's a 2008 gamesday captain, Usually listed for ~$50 on eBay but I don't know how often they actually sell at that price (picked mine up for ~$20)

What shall I do with this guy I got hanging around
