This is what i was thinking of getting...just asking on here if someone has one..id like to get a comment on it :P

And also does it fit a gr16?

Yup, most m4's are tokyo marui clone and will take the m4/m16 style hop up. I think only ICS' are different but I could be wrong...

As far as the madbull chambers, I don't know. Keep searching and scan out sites that sell it for a detailed review. If the king arms is only 10 or 15 bucks more, I say go for it, because you will not be disappointed... You can come over and beat me with a burning toaster if you are, I swear by it.

but recently I have been using the New modify units.
they come with 2 arms, one full (nubless) and one open.
I dont mind them But if you forget the little rubber oring under the gearset.
it will not hold the hopup setting.

I have a PDI 455mm TBB with a Guarder Black Rubber with a Modify Hopup chamber using the
Nubless arm (but gently dremeled to a Concave type of feel)
its a snug fit to get the barrel and rubber in.
they are very good together.

Which one did you end up liking best????
