Hi, i'm relatively new to airsoft sniping and i got my first sniper a couple of months ago (well MB01). Recently i started upgrading my rifle to increase accuracy. At this point i did not get a new hopup unit yet and this is where my problem lies. I installed a 6.03mm tbb but my shots veer wildly to the left. After a little research i foudn out that this is due to poor allignment of the hopup rubber or something. Can anyone help with this???? :shrug: It's rather frustrating since my G&G FN2000 shoots further and straighter at this point and it's stock. Any help will be much appreciated!
