Huma Regulator installed in the s510

Updating this thread a little.

I have an AA S510 .22 fac and thinking about install a HuMa regulator. Have yours working fine since they got installed? If i dont do any more mods than the regulator, should i have it on 140-145bar, or does it waste a lot of air even on that pressure?

Mine has been fine. You will need to do more mods than just install the regulator if you want the best function and efficiency. 

But does it still waste a lot of air if i have the regulator at 145bar, anyone tried? Otherwise is it 135bar and lighten the hammer with about 10grams? of course, every weapon is a little different from each other
