[Cheeto]

Hello,

to make it short,

What I have :
CYMA ak hopup unit
300mm barrel
350fps with .20

What I want :
-Normal hopup rubber suggestions
-Currently have a rubber-tube nub, is it worth changing it ? I don't mind modifying the hop-up arm if it's worth it

What I don't want :
-Rhop
-Flat hop

Thanks in advance
