Hi, I have a question about an AR-15 trigger: if you take off the upper, and cock the hammer by hand, then pull the trigger, let the hammer fall, and reset the hammer by hand, and you feel it engage the sear, but, you can make it fall again upon trigger reset, by just exerting a little pressure on the hammer from behind...that's not correct, right? Could that cause the rifle to fire doubles? I am guessing that no amount of pressure from behind should allow the hammer to fall until the trigger is first released and then pulled again?
