Hey Akulakat, that is a commonly broken part, so yes there is an upgrade for it however everyone seems to be out of stock including CENDirect.

I'm thinking since the OEM part seems interchangable with the Genesis part, that it could be interchangable with that hop-up part. But I will get back to you to confirm. I have a Genesis and Nemesis to compare to.

Glad you fellas at least had SOME fun!!
