Hello,

i'm from asia, forgive my bad english.
I hav jericho 941 cybergun bb 4.5mm, almost a year and use for targeting practise. Now it seems lost power and accuracy in 10meters. I tried chrono it and only gave around 300 fps somethin (hard to get 400fps as default use).
I always do maintenance every 3 weeks or once in a month: lubricating use silicone oil, grease, etc.
Is there any tuto how to fix it?

Appreciate any advice.
Thankyou.

Cybergun products are generally considered throw-away items (lower-priced and poor if any parts support from manufacturer/sellers). I think you may be on your own and have to take it apart to see if you have any damaged seals.

That being aid- if you over-lubricate things, this can cause problems as well. Maybe lay-off the lubing and shoot it for awhile and see what occurs.

The gun is only rated at 328 FPS:

Also, the gun is airsoft. You might have more luck asking your question on a forum where people know airsoft guns. This forum deals only with lead pellets and steel (.177") BB's. Good luck!
