To those with Generations Tankor

I noticed on a picture of Tankor that his gun attaches via a c-clip. My question is: Is that a standard 3mm clip? Could someone who has both gen Tankor and some c-clip system compatible figures test that out? I know lena is selling some Tankor cannons on their own, so if it's 3mm compatible, I might burn a dollar for a new gun for Breacher. 
Thanks in advance!
Edit: Question answered by a buddy of mine. It's definitely standard 3mm, but it's almost comically over-sized on Breacher. It just doesn't quite work well any way that I found.
Feel free to lock this.
