Low pressure
Low pressure? What is it? Low pressure is exactly what it says it is, Low Pressure for your gun. Low pressure can improve your accuracy and help conserve co2 or compressed air. The key fundamental behind LP (low pressure) is high flow and low pressure. Low pressure improves your accuracy by allowing the gas to slowly push the ball out of the barrel, instead of smashing it out with high pressure. Down below are some things that you can do to make your gun low pressure. To make your gun truly low pressure you need a regulator, if you do everything on this page except getting a regulator your gun will not be low pressure. When you have a regulator you can run your gun as low as 400psi.
What you need to get for low pressure:
An adjustable regulator (Recommended: Palmers for co2 and Air America Vigilante for compressed air)
High flow valve (Recommended: AKA turbo valve)
A barrel no longer than 14 inches with as little porting as possible.
Spring kit (Recommended: Madman Spring kit)
Down below are some things that you can do for almost free to help your gun with low pressure.
Drill out your Vertical adapter (the place where your co2 screws in)
Modifying your bolt (I would not recommend getting a new bolt because the stock one will work excellent for low pressure without costing you extra money)
Polishing your internals (makes your gun work smoothly)
