Thank you for inquiring about our triggers. The BFSIII HK-C1 should work in most HK 91, 93, MP5 it should also function with variants and clones of these firearms.

I installed it in the mine but it seems like when I go binary I tend to have failure to eject it grabs it too fast so I don't know if I just need better magazines a better ejector or a heavier bolt because it's too fast
