Already did that. Thats how we came to 890. We used a maxflow. Its effin ridiculously consistent at that spot. Like complete shot full of holes all my preconceived notions of needing secondary regs and what not. Single sweetspotted reg will do the trick

You need a secondary reg because most primary regs pressure will go up as the bottle pressure goes down. Older manifold Max Flows work well in a single reg operation.

Is it a big deal that the bottle pressure is going down?

Ask Ninja to shim one to the pressure you need.

Yes, the way a reg works is based on input pressure and the spring. If you are only using one reg on a gun and it isnt capable of compensating for the input difference, then your output pressure to the gun changes. Most guns would not work well with an output change of 100psi-200psi. Thats why you use a secondary reg, that 100psi-200psi change into the secondary reg equates to 2psi-10psi change to the gun. Now the older double stacked Max-Flows were good as a single reg system, and supposedly the older Nitro Duck Mega regs and such are able to compensate, but I have never tested the Nitro Duck myself. Run a secondary reg for consistent FPS throughout the whole tanks air supply.

I thought the inline max-flos were also input pressure compensated. No?

They have a base cup and seal at the bottom of the poppet. That's actually ported through the poppet to the low pressure side though, isn't it? That balanced poppet design isn't the end of the input pressure compensation?

^^^ Just trying to remember there.

if you get ahold of an old evil scion tank reg, you can go over 1500 if you're not careful, just make sure you use steel braided and not macro

Honestly, I dont know or remember. I think the older large versions are probably similar, im just not sure if making it work as a vertical changed the way it operates.
