That is a good question, most likely not as the hammer would be in the fired position and could not be reset by the standard cycling unless you manually reset it.
The previous answer from the EXPERT is WRONG!!! You CAN put it back into SAFE after the first shot on binary before releasing the trigger for the second shot. Once you’ve put the safety selector back on safe from binary you can release the trigger WITHOUT it firing.
Yes if you move the selector back to semi or safe position the second (or release) shot will not fire. The other guy that answered your question doesn’t know of what he is speaking.
Yes, if you flip back to semi, the mechanism on the back of the assembly, which is held forward by the required auto bolt carrier (not included), falls backward into the fire control selector, which engages the disconnect. When you let go of the trigger, it will not fire the chambered round. I have installed several of these.
Fostech recommends that you move the seletor to semi in order to negate the 2nd round. You cannot move the selector straight to safe once 1st round is fired.
In a way yes but not directly with the safety selector. In order to prevent the 2nd bullet from firing in echo mode you must keep the trigger fully compressed and do not let go. While keeping constant rearward pressure on the trigger you must slide the echo paddle to semi, only after you do this may you let go of the trigger. You should hear a click. This prevents the second bullet from firing. Be careful because if you press the trigger again after letting go of the trigger it will shoot a round. You can now switch the safety selector to safe and the gun will be on safe. You must follow these instuctions exactly for this to work. You cannot switch the gun to safety while the trigger is compressed in echo, you must hold the trigger after shooting your first round and switch the gun from echo to semi and then let go of the trigger after doing so. You can always put the gun on safe before you shoot your first round however without moving the paddle, this method only applies when you have the trigger compressed in echo between shots. I hope this helps.
FOR THE EXPERTS: On the product page, in the 'Features of Fostech Echo AR-II Drop-In Trigger' section, it clearly states, "When the shooter is in the Echo Mode and depresses the trigger, one round is fired. If the target moves(if the shooter decides they don't want the "Echo" round), the shooter can move the selector to the safe position(while holding the trigger in the fired position) and a second round will not fire upon release."
Yes. You can do just as you described.
No idea if you can on the Echo but you are able to on Franklin Binary Trigger.
The Echo Trigger is designed with safety being the utmost priority. When the shooter is in the Echo Mode and depresses the trigger one round is fired if the target moves the shooter can move the selector to the safe position and a second round will not fire upon release..
