GHK AKM GBBR Hop Up Issue

[Fiya]

I love my GHK AKM... However it looks like the hop-up rubber EDIT: BUCKING (Not rubber) has been ripped. I really need some help.

Well I'm especially a newb when it comes to GBBRs. For some reason I cannot find where to buy hop up bucking for this thing. I found one earlier that was advertised for the GHK AK's, but I believe that would be the older models. (Its apparently a new gas system.)

Please tell me that I'm being stupid/Its a regular ass hop up bucking and I can get one in Canada.

I REALLY want to get this thing chronied and run it at Claybank on June 9th/10th! (As long as its under limits of course.)


EDIT: Going to do more extensive testing... But looks like it doesn't matter. Haha! Its firing reliably and accurately, cleaned it, removed a little of the bucking from the internals and its firing like day one. Jeez, those damn AKs. :P
