FGC-9 MKI / MKII MKIISD brass catcher frame

you can just slide this one in the type of brass catcher shown in the pictures. this model can be found at places like Aliexpress. what the frame will do is make sure that is stays open and helps to presents from folding that would restricts the cases from getting out of the ejection port it’s made to work with the MKII but it will work with the MKI models as well I have noticed that it could use a spacer piece in the part where it clamps down. so it doesn't pull the brass catcher in a angle a M5 knob have been added so it's more easy to remove or tighten by hand. the “PLUS part” can be placed in the rail on your shroud to remove some play (this is for the older shrouds the MKIISD mini rail wil not be needing this part.)
