Help with name of a part of gun magazine (g&g brand)

[apparition_]

So I got a new g&g m4 cm16 raider GBB and uh I somehow managed to pop out the little piece on the magazine that holds the bb in place when you push each BB inside of the magazine. Wanted to see if I can find a replacement online or something but I have no clue what the name of the piece is. A pic of of where the piece *was* can be found here: http://oi40.tinypic.com/op1b9s.jpg Can anyone help me out? (Forgot to add that I lost the piece since this happened while I was standing in grass... )

Did your gun not come with a manual, most GBB's have exploded diagrams with the parts and associated parts #

Yeah it did, but it listed the magazine as a part instead of exploding it aswell
