Tuning Benjamin Kratos cocking lever

The bolt should have a spring inside the action that holds it closed when closed. It's a cam over design. Has it always been like that or has it been disassembled? 

There is an adjustment Allen screw that you can use to adjust the amount of tension. It is located on the opposite side of the chamber just above where the pellet probe comes out.



You will need to sacrifice a metric Allen key by cutting it down close to where the 90-degree bend is to fit it inside the chamber space.

Yes, the Cayden I have, the lever could come unlocked if I hit or jarred it slightly. Once I tightened up the screw, it locked in place and stays put..

I have the same issue, but to a lesser extent than the OP, on my Cayden. Just tried the adjustment screw routine, and it is much better!
