Barrett M82A1 drag bag

Anyone aware of someone producing a quality drag bag for the Barrett M82A1 semi so that it can be carried in it’s fully assembled form?

So far this Haz Mat bag is the only thing I’ve come across.

Thank you. I’ll inquire on pricing and availabilty.

Appreciate having a second option to begin researching.
