I'm with Thomas on this. You don't need to remove the cocking arm. First, install the end of the cocking arm in the slot of the action/piston WITHOUT the mainspring installed yet. Second, insert the barrel/breech block between the forks with the barrel in a cocked-open state. (You won't be able to insert the barrel beween the forks with the barrel straight, because of pressure from the ball detent.) You should be able to align everything without fighting any spring pressure (either from the main spring or the ball detent).Good Luck!

Unless im missing something here, i would have to compress everything with the barrel installed using the above method right?
