Here you go, showing my pair of Titan MPTs, the Mk1 on the top and Mk2 on the bottom

and close up of the action on my Mk2 showing the 'knob' behind the bolt that is to cock the action. This knob is at the end of the cocking 'bar'/'rod' ....
The bolt is pulled back, touches this and pulling the bolt further back, pulls this back as well, cocking the action. I tend to use it double action, ie cock the action first and then load the pellet using the bolt thereby defeating the whole purpose of the Mk2! This reduces the force needed to operate the bolt.
Accuracy of both is excellent. TBH, haven't used them much recently so I'm going to refrain from qualifying that
Hope this helps
