I've tried two different barrels and three different hop up rubbers and each time I fit this unit it pinches the mouth of the rubber closed so that BB's can't feed into the barrel correctly. I don't know if this is common or I've just got unlucky but I've had to switch back to the original plastic unit for now.
@@xtairsoft I did purchase it from ak2m4 however, it was quite some time ago and only just got round to fitting it. I was trying to install the unit inside an LCT AK however, I confirmed what was happening outside the AEG. So fitment inside the AEG wasn't an issue, there was nothing forcing the barrel back. I tried a ZCI and stock LCT barrel, as well as a Macaron, Prommy Purple and stock LCT hop rubbers. All did same thing and forced the mouth of the hop rubber to narrow unless I pulled the barrel forwards (without the C-clip installed). I have to assume the lip inside the unit wasn't cut as far back as it should be, but it being a CNC milled unit I can't see how that would be possible. That lip inside is quite sharp and digs into the feed lip of the hop up rubber.
Noice, is that a silicon hop rubber you have there
Yeah, it's just the basic ZCI that comes with the chamber

Will this work with cyma Ak's ?
I'm not sure
