Based on your figures that makes 1500 ish off a 68/4500psi so thats good yes
I figured 160 per lock lid and 200 for the hopper = 1000 shots off 3000psi
Its a shame it takes a long time to get a GEO 2 but from everything I have read they appear to be worth the wait. At least this launch there hasnt yet been any recalls or product updates, such as Plank kit for EGO9, GR2 for GEO1 etc so planet got it right first time, just took a couple months extra.
To be honest if I was paying top whack for one Id expect it to be mint / flawless so them holding back a week or so to send out "A" grade guns seems sensible. Heck, its been about 2 months longer than expected to wait so far, whats a little more time...
