A post I made elsewhere regarding the Hyper3 reg-
First off the Hyper3 reg has what looks like 9/16"-16 threads on it, so I guess this is the jump into getting away from the old "ASA" as a foregrip mount.
They downsized form a 0.993" to a 0.745" reg piston plunger, and use 12 15mm OD x 0.6mm thick Belleville springs instead of the 9 18mm OD x 1mm thick stack.
The piston surface is almost 1/2 of what it used to be... to me, that is only 1/2 the accuracy of detecting output air pressure. I could see if the spring stack were 2x the travel, but it is only 0.5mm longer overall travel. Makes me wonder about the "more consistent" claim.
I just looked up the specs on the springs used, and it looks like the previous Hyper regs were over-sprung. They would reach the spring stack's load force at 320psi. The Hyper3 is sprung to max right around 200psi, so that is where any real performance increases might result from.
One way to find out... put them on a gun, hook up the pressure monitors, and let it rip!
According to Dye (http://www.dyeprecision.com/HardParts/hyper3.html)
, it says "Features standard threads to fit most markers", which I guess is a typo left over from the text they took it from, because all of the regs pictured on that page have the same smaller size threads (relative to the reg body) as the one I have here. Two tops would be a good idea.. easier for the transition phase at least.
