BB's falling out of barrel

[BLKKROW89]

So i noticed the other day when i fire my CM031, in fully auto mode i will pull the trigger let it shoot 6-10 rounds then stop then a bb will roll out of the barrel.

Any idea why i have an element hop up/bucking. And a tightbore barrel. so i dont know if it is just a common issues or what

Try adjusting your hop up, we have the same problem on our JG MP5 when our hop is too low.

it sounds like the bucking or the barrel is too far in or too far out
1. lube the bucking in and out
2. slide on barrel
3. push the barrel with bucking softly until you see the lines of the barrel then put the cap on it

OR

your hopup assambly is not placed right this happens if the spring isnt on the hopup or it it isnt place right
