Question - if you upgrade a dreadnought arm that has a built-in weapon (storm bolter, for example), do you keep the built in weapon?
I used to think no - if you upgraded a
DCCW/
SB to the
TL Autocannon, you lose the storm bolter.
But I also recently purchased a Ironclad Dreadnought, and it has the option to upgrade it's seismic hammer to chainfist. This would leave me to believe that you don't get the meltagun with it - but the model (and even the official games workshop pictures on their website) have the melta gun.
And I did check - the wording is similar in all cases for the dreadnoughts - the only weapon upgrade/switch that accounts for the built in weapon is the Ironclads right side
DCCW/
SB combo.
For reference, the link to the Ironclad:

So how does that work?
