Hi-cap Dragon mag broke

Ok I have a Hi-cap dragon mag that broke what broke was the piece in the top of the mag were the BBs sit in the two pieces well one side broke off so the BBS wont stay in the mag I am not sure how it broke I was using the gun one day and I went to shoot it and it shot like 10 BBS at once I thought what the heck just happened I pulled the mag out and the rest of the 30 rounds just went every were and I saw that one of the little finger things holding the BBS in the mag was broke (not sure what they are really called) I am wondering if they make replacement parts for this I know that that piece comes off but I don\'t know if they make replacements or do I have to buy a new mag? any help will be appreciated if you can understand what piece i am talking about i can try to post a picture if nobody gets what im saying if I can figure out how its been awhile since I was on here. Thanks

I know it is a WE brand part but it SHOULD work on a TM.... but I don't know for certain.
