Transferable MAC 11

Made a post about this months ago, thinking about parting ways with my SWD Transferable MAC 11. Has a LAGE MAX 11K upper and 8 shockwave mags. How much can I get for it realistically. I am 25 and not rich at all, so I could use the funds to pay off debt. With FRT’S legal again does it even make sense for me to keep it ?
