Socom m107 shell ejecting 6mm co2 airsoft gun (read description)

This is my amazing barrett m107 gbb sadly just after one use the gun had a major malfunction and blew up breaking the trigger mechanism and fill port the pistol grip is now held in by a bolt just for authentic look i have been contacting the manufacturers for part but after a year of no reply its time to say good bye this is now a model atm if you are willing to get the parts to replace it I have a list of what it needs but it makes a great replica for display
