ACR Gel Hopup

thingiverse

This is a customized version of Matty's MHV.1 Hopup, modified with a 14mm LH thread to fit the JM J10 ACR Gel gun perfectly. To set up your inner barrel, you need to shorten it so that only 5mm protrudes beyond the threads on the factory outer barrel. Once you've done this, you can screw down the entire length of the factory ACR outer barrel using this hopup. The grub screws used in this design are M4, and I've relocated the barrel clamp screw to the underside of the hopup for added convenience. I'd like to extend my gratitude to Matty for his hard work on designing this hopup and sharing the editable files with the community. He's done a fantastic job!
