l96 hopup... not moving much :S

[badas]

hi all, have my first sniper with me, MZ l96 just took it apart for the first time and come to the hopup with intension on seeing how its built and if i could add a madbull h bucking maybe.....

so got the the L96's stock hopup thats still connected to a stock barrel but if i alter the adjustment screw whilst looking down the barrel its not moving hardly at all....

is this normal for a sniper / l96 stock hopup or should it be mooving noticable like an AEG's hopup?


also the barrel spacers, the ones i have a foam, whats the best make of barel spacers and if i do change them what difference willi get in acuracy etc?

also how far should the barrel spacers be apart?

thanks
