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.   Posted: Sun Dec 28, 2014 8:59 pm daynie New Member Joined: 28 Dec 2014 Posts: 4 Any ?   Posted: Mon Dec 29, 2014 1:32 pm AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6908 Location: "Out There" 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. _________________ ` I'd say "I care." But I'd be lying.

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! _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Sat Jan 10, 2015 8:49 am daynie New Member Joined: 28 Dec 2014 Posts: 4 I'm sorry i mean airgun jericho 941.
