Hey airsofters. I was driving today and I had a burning question in my mind. I have upraded the inner barrel to a Promethesus 6.03 inner barrel a few months ago to hopefully increase the accuracy of my gun. When I fire my CA M15A4 at close distances, it is pretty consistent as I can hit small targets most of the time. At farther distances, my gun is a bit more inconsistent as some bb's fly higher/lower than others. This may be a dumb question, but would upgrading the other internals, ie. air nozzle, piston/piston head or cylinder help to increase the consistency of the power of the gun, and hence, the consistency of the shots?
