disfunctional (broken?)

[KrazyKraut]

Hey folks, pretty new to this forum but.
I've got a pretty standard electric AK47 with a foldable stock. I was trying it out in the basement last week and found that when I keep it on full auto it constantly jams or fires 2 bb's at once. The motor isn't making weird noises so im wondering if it's actually the ammo clip that's broken?

Also my M249 SAW keeps causing my bb's to curve upwards upon firing, any solutions?

Thanks, KK

The double feeding is most likely caused by a screwed up or worn hopup rubber.

On the M249, turn the hopup down.

AK = what brand? are you using a highcap?
M249 = adjust your hop up

1) What BB's are you using? If it's a low quality brand like Firepower I've had jams and double feeding problems before. Either that or it's something like Styrak said about worn/torn hop-up.

2) Use heavier BB's or turn the hop-up down. Tune it so that you get a flat trajectory and the furthest distance.
