Hi,
I recently bought a Kimber Warrior 009 from Only BB guns - yes, I now know it's a bad site, but the gun is OK. It's all metal and has an adjustable hop up, and it looks to be mostly compatible with hi-capa 5.1 parts (it's a clone of the TM kimber but in metal).
I'm not very experienced in airsoft, but I did have a gas non-blowback pistol before which lasted 3-4 mags on one fill of gas. Although GBBs are less efficient by nature, mine only gets through maybe 1/3 to 3/4 of a mag before running out of gas. I'm using a big Abbey predator canister which feels as though it has plenty left (I can feel the compressed gas moving when I shake it), and AFAIK I am filling the mag correctly; it doesn't leak audibly. The efficiency seems to have got worse since it arrived a few days ago.
Would oiling it help? I haven't oiled it yet as I haven't got any silicone oil, but I have stripped it a few times, maybe it is dirty or something...
I can post pics if needed.
What can I do to make it more efficient?
Thanks
