Wondering if anyone had personal optimal settings for tuning the IV propshaft?
a) Jack Wood said typical 'stock gsl' setting would be 4 clockwise-turns starting from flush all the way out.
b) Hustle Paintball recommends a setting between 4-8 clockwise-turns starting from flush all the way out.

Question: (referring to Geo3 with IV powercore)
1) turning the propshaft screw in (clockwise) too much = does ? to the marker
2) turning the propshaft screw out (counterclockwise) too much = does ? to the marker?

I wouldn't mind a more detailed clarification from some of the Geo gurus in this group. Thanks in advance. <3

In too far = Drop off
Out too far = Wasted gas
As stated in the manual that comes with the IV core.

In your professional opinion would you suggest "opto" or "switch" to shoot faster and really be able to rip on the trigger?

Can anyone confirm if this o-ring kit from has the correct 'middle o-ring'? From the looks of it, I believe they are using a 14x2 but I'm not positive.

I've been having this problem with my Dynasty 2.1 and hoping this o-ring kit will fix this issue.

EDIT: Nvm, just bought a Core IV

I recently bought a used CS1 off trademygun. I used it about 5 times already. The first few times I used it in tournaments and practice, it was fine. lately I have been noticing (especially in hot weather) that after I put about a case through it, it starts shooting VERY low fps (around 160 - 200fps) It is the worst when i take the first few shots, but the fps increases slightly in ramping. However, it does not reach 300fps even in ramping. I have tried lubing the bolt before every point and applying more after each. However, this does not help the problem at all. I dont know if it is a bolt issue or a regulator issue or what it could possibly be. Before this happened, I lubed the regulator and piston o rings. I will try again with everything freshly lubed and see what happens. Please let me know what the issue could be caused by and how to fix it. Thanks.

I just bought Geo in great condition. I know it's an old gun but I'm also having the same issue, not shooting where it needs to be (280-300fps). It's shooting very low, around 200-240fps. I've cleaned reg and piston, fresh lube, new battery, etc. Looked over everything I've learned in the past few days in order to fix it but no luck. It has the G-R2 kit installed. Any info would be appreciated. Thanks.

When I replaced the o rings on my bolt tip it seemed to work. I also re lubed the regulator and bolt. Try replacing your o rings on the bolt and see if it works. Hope it helps.

Yes.

[kobu]

Has anyone tried anything different with the bumper(s) on the cs2 like a lil bigger or softer? Just curious seen that NASA thing for the dsr and started wondering

[going_home]

Not on the Gamma Pro Core but with the regular Gamma Core yes I have.

I use 60 durometer Viton 013 Orings for both the Bolt Bumper and Bolt Guide Bumper.

I also use other HP Orings/Xrings in other places.

They have held up just fine for at least 6 cases now.

In my opinion it smooths out the shot quality a little bit.
