Air Efficiency

[Kyle.Kimber]

Its not really rocket science. I do use a level 10 bolt with the red spring. It is well tuned. If I couldn't find a proper fitting oring carrier combination, I kept changing orings until I found one that worked.

I keep my velocity set to about 280fps. Going higher consumes much more air for minimal gain in distance or impact.

I use a 12" or a 16" barrel that is stepped(.695" step) but the porting doesn't start until 6" from the back(only 4 holes from 6 - 8 inches). The barrel porting is small with only 12 holes total until you get to the muzzle brake. The tiny porting actually allows the barrel to maintain pressure behind the ball so it quiets it down without sacrificing a lot of gas efficiency. You can feel the pressure if you take the muzzle brake off and blow through the barrel. I also make sure the barrel insert fits the balls I am using. I tend to err on the large size for best consistency. Overall, I think ported barrels that don't fit the balls are the single largest contributors to inefficient gun setups.

Wait, THE RED SPRING IS FOR velocity 300+. Well thats what I think. I could of sworn that was in the PC manual. I tried the red spring, and I had to up the velocity to 300, just for it to shoot. Mistake me if I'm wrong. I could of just been seeing things.

Each setup is different. Most people use the red spring.
