| Does anyone know the reason the AR-15 was designed in such a way that the hammer must be cocked to put the selector on safe? I'm not complaining, I'm just wondering the reasoning behind it. |

I'm not worried about it at all, I was just curious if there was a particular reason behind the design that someone on here might know about. It probably has something to do with the mechanics of having a full auto fire control group if I had to guess. Really have no clue. Just curious.
I was kinda thinking along the lines how that the AK safety selector on safe allows the bolt to be pulled back far enough to eject a round, but not go far enough back to strip a new round from a magazine. That was an obvious design feature. That's the line of though that brought up this question if that makes sense. |

Not me but good explanation: "That's normal.
Closely examine the trigger mechanism and the function of the safety. When the hammer is not cocked, it holds the trigger down slightly. This raises the rear of the trigger and prevents the safety from being rotated. When the hammer is cocked, this allows the trigger spring to push the front of the trigger up behind the hammer catch, and lowers the back of the trigger enough to clear the safety. If the rear of the trigger were low enough to rotate the safety when the hammer was not cocked, then it would also allow the trigger to move enough to release the hammer when on "safe". It's the way the AR lower is designed. It is an extremely simple design without any linkages or extra parts to fail or jam... but it was designed with the thought in mind that it would be used by military personnel, who would tend to carry "cocked and locked". The same is true of other weapons... the 1911 cannot be put on "safe" unless the hammer is pulled back." __________________ |
