GUNS MODIFY 4 Lbs Trigger Pull Sear for Marui G-Series GBB Airsoft ( 2020 Version )

Doesn't work very well in Guarder hammer assembly(Trigger pull actually gets stiffer but trigger won't return occasionally and sometimes fail to cock the hammer resulting a 2~3 round burst. BUT it works well in KJ works KP-17 stock hammer assembly. My only concern is wearing the sear out due to increased force and friction. But I think it'll be okay unless you use included 140% hammer spring(I'm using KJ works stock hammer spring rn).
