I use a TKO impulse and I have a check it clamping neck, blue I frame, dye grip, vision, freak, check it unimount and NDZ hammer assembly, also vert max flow, and voodoo bolt with titanium pin, and tapeworm.
It is one of the fastest trigger on the market no matter what gun.
They are really expensive
This trigger owns all dude. It will shoot 20 bps if you have good fingers and the right board, even though it is expensive it is worth it. It has balanced my gun out unbelievably I dont even need my drop anymore. I have the snatch grips on it and it is definetly easier to hold since it is so far forward. It also is awesomely adjustable. This trigger owns all triggers no matter what gun.
If you have an impulse get one you won't regret it.
