longer barrel = different cylinder?

[richy b]

hi guys im just about finished on my g36AG conversion.
but im putting in a longer inner barrel 500mm i think i read somewhere that if you have a longer barrel you need a cylinder with a smaller or no hole?

anyone got any experiance of this-any help would be apreciated.
cheers rich

you can't get different size cylinders, i don't think?

its not the size i think, but the positioning of the hole? may be i was just imagining things?

500mm+ = no porting.

Yes, you will need a non ported (Type 0 or A) cylinder to retain muzzle energy effiency with the longer barrel.
It works vice versa, a non ported cylinder paired with a short barrel would be less efficient with common bb weights.
