Hi guys I have a quick question on my Jkhan Krosa Noblesse I am new to this rifle I have had several pcp's now which i had tuned which where my air arms s200 air arms s400 and air arms s410 and I didn't find a problem with those has they where good to tune using the hammer spring and transfer port. But I have found with the Noblesse when I have taken it apart the only part I can find on the rifle to adjust is the hammer spring. If anyone on site has any experience with tuning this rifle could you please drop me a msg explaining how to do so. As I cannot believe the only adjustment there is on the Noblesse is the hammer spring and making the transfer port larger so any help guys would be most welcome thx.
