2015 Spyder Xtra - Mid Pressure?

[nak81783]

Does anyone know if the 2015 Spyder Xtra can run on 500-550psi to achieve 280-300fps out of the box or just with changing out the springs? The Eko valve seems to have the input port geometry, pin geometry, and dedicated blow back hole that are typical on some other low pressure valves (e.g., Azodin KD3). From various YouTube videos specific to the 2015 Xtra, the bolt seems to be the 3 oring type - both sides of bolt input port and one at the nose/barrel end. I'm curious if these features and different springs could get it to mid pressure without a low pressure chamber and high pressure regulator.

If your barrel isn't enormous then the answer is usually yes out of the box.

If your barrel is like a 695 or something you will want a smaller bore barrel.
