Missing A&K m249 Part

[PhatNinjaKing]

I'm not sure exactly what it is called, it sits in the mag well, helps feed the bb's and holds the hop up unit in place. I am looking for this part after a custom job went awry, to say the least.

Any way any help in identifying the part or finding a replacement, or if need be suggesting a different route will be much appreciated.



Thanks!
