but doesn't a tightbore raise the speed by about 10 fps?
Also, I read on many forum posts about how people hate a few plastic internals. Do you still think leaving it stock is the way to go, or replace them with metal parts. I just don't want to have to do internal work here (because I'm an airsoft tech noob), so I would prefer to get it done and out of the way.
And if I choose to upgrade the velocity, will the battery drain at a much faster rate?
