SEAR System Answered

Can anyone explain how they work, and what else would be considered a NON-BLOCK TRIGGER.


all i want is a simple easy way to make a firing mechanism for a crossbow im making

. Not sure this will apply to K'nex, but to see how the "big boys" do it, Google: sear +BAR -Sears -grill . or sear +M-16

it works that the firing pin is blocced by a sort of "thing" that it blocks from going and whenthe trigger is pulled the "thing spins or sumthing and the firing pin can go

thats with a sear system
