Isn't this what some refer to as a binary trigger? I don't know much about gun except when you pull the trigger they are SUPPOSED to go pew or pew pew or pewpewpewpewpewpewpewpewpewpewpewpewpewpewpewpewpewpewpewpewpewpewpewpewpew!!!!!
Yes , you are correct. On RW Arms they are referred to as echo triggers. You have to learn how to use it. Kind of like the bump stocks, I never could get it to work like I though it should.
