Hmmm- looks like an auto, but manually operated?
First, remove the trigger group and carrier assembly. Move the bolt to the rear until the firing pin stop pin is aligned w/ the bolt locking hole on the left side of the receiver. It will be necessary to use a small dental pick to push the stop pin out towards the outside of the receiver. The bolt then has to be moved to the forward position and pushed into the locked position. Then push the firing pin all the way forward and you can remove the bolt handle.
What we have here is... failure- to communicate.
