DvZ'BRN Takedown Receiver
From DevilZ' Nerfworks:
"This thing is what kicked off Cpt Slugs development of his own takedown and interchangeable magwell.
It is a finished design and I spent a lot of time polishing it. If you enjoy what I did here and think I deserve your support, consider dropping by my Patreon: https://www.patreon.com/join/devilznerf?"
