I noticed a difference with nummech piston. I will likely have to pick up a few for my other markers. I am sure some people may or may not see the benefit in this, but i think these are cool for the guy trying to squeeze every drop out of his marker.BeardedWorks.com (Your Inception Designs and Shocktech Dealer)

It's one of those little details that I really appreciate.Dulce et decorum est pro comoedia mori

I'm a little confused. A higher flowing piston to allow a lower operating pressure, or tank input pressure? Flow through the piston should only be relevant immediately after the shot, when the reg opens... and the idea is that a typical reg piston starves the gun if you run too low an OP, but not at higher OPs?
If my memory serves, volumetric flow depends exclusively on the port diameter/ geometry if there's a good difference between the two pressures (e.g. dropping from 800psi to 350), but that flow will slow down as downstream pressure, that is, operating pressure, increases.
I'm interested in a dyno test, with upstream pressure known and downstream at several setpoints, as much to understand the velocity through the reg piston as anything. I'd recommend at least one point at a 2:1 upstream to downstream ratio, one above, and a couple below.
A look at the seat-end corners would be interesting, too - namely, the radii.
The engineer in me is starting to nerd out. I apologize.Feedback

"higher flow which will allow you to run a lower operating pressure"
The spring stack will change the pressure output irrespective of flow. For example: I can take my stock inception reg and flip one washer to achieve lower pressure or add a washer to increase pressure. The inner diameter of the piston would not affect the pressure.
But I get what you are trying to do... the larger inner diameter should increase the response time since the piston will open less height, equaling a reduction in pressure drop from shot to shot. I could, run a really low recharge rate reg at low pressures, if, my flow requirement is only 1shot/5sec. Of the many WGP piston iterations, I do notice these benefits from a larger piston diameter base(pictured left below)
These are all the same dimension in length:
Another mod I have done for flow, is drill extra holes in the reg seat on WGP LPRs and HPRs air supply, this upstream will choke out the downstream. I don't have a good picture of a modded one, but this will give you an idea. edit: this was off an eBay gun I bought titled leaking, I found the leak.
