Crash - River's iconic weapon is bugged. It stays in inventory as quest item. If you upgreade it you will have 2 so you can make legendary versions infinite time. You cannot dismantle it, drop it, sell it or put into stash both home and car's one. There seems to be quite more quest rewards that stays flagged as quest items that cannot be sold or dismantled, but real problem is they cannot be also stashed and those items doesn't weight nothing. I know there seems to also be same problem with Skippy and Johnny's gun, but don't have them yet.
