Any one have any C20 replacement parts for my HGAW Double X Gundam?

Exactly what it says. Since MechaPartsGuy is liquifying, I’ve decided to ask here if anyone by any chance has a spare C20 part for my HGAW Double X Gundam. Part C20 is the front/barrel of the XX’s Beam Rifle, so although I’m not missing out much, I’d very much appreciate it if someone provides me one as mine went up and vanished during assembly.
