I had typed a long post asking about this hopup with links but i was logged off and lost the whole post so ill make this much shorter.
Ive got a jg version 2 shooting 400 out of the box going into a CA M15 metal body with a systema 509mm tightbore.
I need a hopup and see this G&P one on airsoftparts. It has no info on the type of rubber it is and i have been looking around other places and havent found much on it. The one post I saw on here was talking about it going into a tm or jg body (I think).

Anyone have any idea if it will work? Or will I have to replace the rubber as the gun will probably shoot over 400 with the tightbore.
Any other options would be considered but I would prefer to buy in Canada to make things quick and easy. ( have ordered from states but at times have a hassle with shipping so just want to avoid this)
Thanks
...still long post lol
