Fulcrum has this guide for owners of the Ares Amoeba Striker AS01 so they can remove the hop-up unit properly... "In this airsoft​ guide I'll be showing you how to remove the hop unit from an Ares Amoeba Striker Airsoft sniper rifle, the airsoft gun in this tutorial is an AS01 Striker but this guide should work with the AS02 and the silly little AS03.

I love the #aresairsoft​ Amoeba family and this Striker is no exception, despite what everyone bangs on about, this gun is more than capable of being a serious threat on the field even when lightly upgraded. We tried an experimental nub which only succeeded in hampering its performance, in this guide I remove the hop unit, remove the troublesome nub and reinstall the unit. I take no responsibility if you balls anything up."
