Airsoft BB speedloader GBB cap.

Here is my part for airsoft BB`s speedloader.
I've got a 6mm BB speedloader, but it loads only AEG mags. To load BBs into gbb mag this loader must have additional plastic part (to push BBs thru gbb mag lastic lips).
So i've decided to make it myself.
This part is designed to fit WE OpenBolt mags, so if you are going to use it with any other system it may require some changes.
