JG g36c shooting up and to the right
 

So, my JG G36c is shooting drastically up and to the right. Is a problem with the hop up, or is it something else? Thanks.

It sounds to me like it's overhopped, with the hop up not aligned with the center point of the gun, rotated slightly to the right, especially if it's a smooth even curve equally up and to the right. If the curve up looks like it's different from the curve right, then it would be two separate issues, but if from the firing position it looks like it's an even parabolic curve upwards that has just been rotated slightly clockwise, then it's the hop up orientation that is the problem. Out of the box my well l96 had that problem, I just rotated the hop up unit counter clockwise inside the barrel and now it's pretty straight.

It can be a variety of thing.

If it's shooting up and right, it could be the hop up, wind, a bent barrel, or your bb's are crap. Did you do anything to it?

Is the trajectory changing up and to the right or did you just not adjust your sights?

I'm using elite force .25s and the trajectory is definitely changing. How should i fix it? i happens even without wind.

If it's consistently going up to the right, it's probably your sights that need adjusting.

If it's inconsistent groupings you could try a variety of things, mostly to check if anything is broken/damaged.

Turn off the hop up, take out the inner barrel and see if it is bent/warped, look in the barrel to see if it's scratched inside, etc.

If you're testing if your sights are zero'd while standing i'd highly recommend you do it proned with the magazine on the floor to minimize human error and movement. There's a good chance you're missing just because you're not shooting properly.

Changing trajectory means hop. I've worked on a friend's jg g36c and the stock hop was rather bad, fixed in 30min by flat hopping it.

Does it come out to the right or does it come out straight and then curve to the right?

it goes straight for a about a meter then curves right.
