been years, think i got some from redwolf some from ehobby.
they used to have an english option on the laylax site but its gone now so getting accurate discriptions are hard.
i know jugglez (airsoftparts) useually has some laylax stuff but hes sold out of hop chambers atm, ask him im sure he will get it for you.
i like the laylax one it works the same as the stock one keeps it simple

at that price may as well get it for 95 from jugglez
