Miss-shot is normal ?
 

I have my brand new Ares G36C !
I just need a better battery ... The one from my old Crossman NightProwler suck...

However is it normal sometime it does not shot any bb and the next time 2 bb is shot ?

I dont think so but can it be the battery ? (It take time to shot between my trigger press and the spring released ... )

Feeding issue having to do with mags and/or hopup probably. Try a different magazine, BBs, make sure your mags are clean and oiled.

Issue is NOT your battery, however bad it may be.

Make sure that the hop up is not set all the way up, I know it sound silly ,but it happens...

The mags are the official one from Ares and new from ... yesterday... ! So if its not clean ... :O
i'll try with different BB !

However if it does not work, how to oil a mag ?

Are you using a hicap mag? I'm told that they can sometimes do that. Try using a midcap or lowcap mag (ie. one where you don't have to wind the bottom of the mag constantly).

Could also be the BB's you're using so try different BB's.

I would usually chalk to this kind of behaviour to mag problems so try different brand/capacity of mag to see what happens. If it stops then you've solved your problem but if it still happens you've got bigger problems on your hands.

Most likely the cheap hop-up rubber.

I ordered a replacement G36 hop-up unit that came with the rubber, and I ended using a worn TM rubber instead because it was jamming just like you describe.

Try different brand BBs. They can make a world of a difference on how well a gun feeds.

Thank everybody i'll try that !
