Pro Win Hop Up
 

Hi guys,

For all you folks out there upgrading Kraken, watch out for the Pro Win metal hop up unit, it create an airleak. I m trying to fix it. If anyone solved that issue, please let me know how you did so :)

Thanks,

Thank you for the heads-up! I was planning on a Pro-Win hopup for mine. Not anymore...

I have one for my G36C, and i have had no problems with it, other then the fact i had to dremel out some metal on it to make it fit in a CA gun.

I've got one on my Kraken... It works perfectly...

Are you sure you've installed it correctly?
