Misfeeding- firing two bbs at a time

[Death fighter]

Hi I have a classic army ca36c,

It seems to be firing two bbs at one time?

Anybody know how to fix this?

Thanks

The bucking may be warn down, or the hop up unit may not be seated properly.

^^ What he said. My guess is the bucking. Usually the lip is worn and allows a BB trough without resistance. Drop a BB in and see if you can push it into the bucking without or with very very little resistance.

It's most likely what the guys above have said, but I have also found bad BBs to cause double feeding.
