HPA tapped AW drum mag feeding issue

[JSilversides]

Looking for a solution here, I have recently installed a Hadron bouncer kit in my AAP-01 along with a flamingo 60 bucking and a Hadron H plate, and noticed something is causing my HPA tapped AW drum mag to dry fire every 4-5 bb’s. I’m fairly certain it’s either the drum mag or my HPA rig causing the issue as when I use the standard gas mag that came with my aap there are no issues, however I’m at a loss as to what it could be. I don’t think it’s a ROF issue given that my regulator still seems to be keeping up and my gun is still giving me good blowback on the dry fires, the drum mag is still winding ok and pulling bb’s to the top too.

any help would be appreciated
