recoil spring upgrade

[jkz]

Hi i'm trying to install a kings arms recoil spring guide upgrade into my ksc gbb usp 45. Unfortunately i've taken out the original spring guide and taken it apart and i don't have a clue how to install the upgrade spring. Can anyone help please. I would be grateful for any assistance. Thanks
The blue arrow is the new spring guide upgrade and the black arrow is the stock spring system.
