If you are referring to a "SET Trigger" on a rifle. The Set Trigger releases all the normal mechanisms in the action but does not release the hammer on the rifle, but it sets up the firing trigger to act like a "Hair Trigger" just barley touch the firing trigger and the rifle goes off. It's used in hunting. It is common on black powder "Hawkins Rifles."
rifle basix makes the trigger of your dreams..
On some of the older rifles, they had a set trigger. You would pull it first to set the other trigger. The second trigger would be a hair trigger. It would have a very light pull. The first trigger was supposed to keep from accidentally firing the rifle as you were aquiring the target.
Do you mean "what is an automatic Rifle". Any rifle that keeps firing as long as you hold the trigger down is an automatic rifle. It will only stop when you let go of the trigger or run out of bullets
Rear trigger is "set" trigger, by pulling it 1st, it makes the main trigger a "hair" or lighter trigger
