a super smooth ram? and the arbor honing?

[FlipFlops]

Actually the main reason is that it uses the super heavy Freeflow hammer, which means there is a very light main spring. Light mainspring = lower cocking pressure, since the ram has to do less work to cock the gun.

but isn't the recocking pressure (penumatic pressure) so low aready that even if you gun has a low operating pressure, it wont make a difference on the pneumatics.

I am asking what allows the pneumatic pressure to be so low? What does the free flow have, that makes is be able to cycle at what? 35psi?

[Knick Knack]

He told you. The key is a light mainspring. The mainspring is the largest force the ram has to work against, and so when you reduce the mainspring pressure, it reduces the force the ram needs to overcome it. Now, since the free flows dont run at low pressure (or lower pressure), and they use a medium valve spring, in order to get good velocity and efficiecny, they use a heavier hammer.

So, in order to get lower cocking pressure, you need to replace your heavy mainspring for a light one, and replace your light hammer for a heavy one.

so if i use that bolt with the light spring, i will get the same results?

[FlipFlops]

Bolt? Who's talking about bolts?

Remember: Autocockers have two seperate things going on. Input pressure through a valve that fires the ball, and a (very) low pressure regulator that runs the pneumatics to pump the gun. The two are not related!

Freeflows run at 300 psi input pressure right out of the box, but their pneumatics run at 30-40 psi. Freeflows are NOT low pressure autocockers, yet they get excellent efficiency and are very quiet. They don't chop paint because the recocking pressure is low (attained by using a heavy hammer and light main spring).

Well there are several steps taken to lower your recock pressure. And using a light mainspring is probably the biggest factor but there are other things done in which to make it that low, some step, if not taken will restrict you from have such a low pressure. Now although they use a light main spring, another large factor is internal polishing. You may have a really light main spring but unless you reduce your friction inside the gun, you're not going to be able to get much. Pro Paintball bores out their bodies out to very tight tolerances, and hones and polishes. What this does is reduce the friction of the metal contact inside the gun causing to bolt and hammer to glide back smoothly. Another small, yet over looked feature is the ram itself. They use STO rams unless specified otherwise. These rams have large IDs(internal diameter) and they are well polished, allowing the ram rod to work smoothly inside the casing. Hope this helps you understand a little more.
