Foxbat/Parallax slide return

Pretty simple mod, only replaces the barrel cover. You will need 11 coils of k31 spring (or similar spring size but weaker), put it around the barrel and stretch it until the spring is ~10cm long when resting.

The only scary part is that you need to cut a slot into the plunger tube, like shown here: 📷 Image redacted — claim this model to add your own media Then, before you slide the barrel into your build, put the spring into the barrel cover so it goes around the barrel.
