What is the drop rate of damaged necramech weapon parts from the Isolation vault bounty?

I feel like I've done tons of T3 bounties and I have yet to get a single weapon part as a reward, at this point I'm beginning to think the drop rates are either extremely low or they are bugged.

They are low, but they do drop. I have two different mech weapon parts from the vault.
I wouldn't stress too much over it since you need to be Rank 4 with the mech standing to even assemble the weapon.

It's actually rank 3, and I'll be rank 3 tomorrow so I was kinda hoping to be able to build the weapon but I don't have a single part.

I might have misremembered. Well the good news is that building the individual parts doesn't take long. A minute or so.
You don't have to feel the pressure to have the parts ready atleast. Unless DE hotfixes that too, like the necramech farm. 🙂
