Are they any different?

[Puha]

There are a few different models of the IR3 out there and I was just wondering which ones shoot any different. For instance the fly ir3 shoots the same as a stock Ir3 because a fly is only milling as such. Is there any Ir3 aftermarket guns that have more than milling and exterior work done? If so, which ones do you like or don't like and for what reasons?

They are all just different looking and come with possibly different warranties depending on the company who's name they carry.
The Impact, CLASS, and ROCKY all come with a different trigger and im not sure on this one but the cobra might come with a cobra barrel and bolt.

I bieve the cobra comes with a bot and a SS hammer.
