Does the Mosin Nagant design have a safety?
A. Yes, the cocking knob at the rear of the bolt is also the safety. It is placed on safe by pulling it to the rear and rotating it 45 degrees to the left until it can be hooked on the rear of the receiver. This locks back the firing pin, disengages the trigger, and locks the bolt closed. Here is a picture of a Mosin on safe.
