None of the pieces actually have the models as shown in the preview image/thumbnail, as the planned ones where never finished and the ones shown are not allowed by MWS rules and guidelines. Sorry for any inconveniences.

Found across several Murkywater installation the crew... liberated, they managed to aquire an experimental weapon kit from the Murkywater army. With these 3 attachments, the crew is capable of changing their beloved M240B LMG into the ProtoPhage Mk.VII, a big-ass scout rifle war crime massive weapon chambered to fire large, high explosive munitions that are capable of eradicating a Bulldozer in mere seconds, if you can handle it!

This is a mod that adds 3 new weapon parts to the M240B LMG, effectively turning it into the Xenophage Exotic HMG from Destiny 2.
It has high damage & recoil, low mag size & low reserve ammo/pickup, proper explosive bullets, and is slow to reload, but is limited to semi-auto to compensate for some odd animation issues.

Big thanks to TheOnlyMann for using 2 hours of his time to get the weapon's explosive ammunition working!
