Unlike the Geo and Geo2, the Geo2.1 does not have the PCV mounted in the reg swivel collar. The PCV is mounted in the body, above the reg, instead. As such, switching regs will have no effect, as the problem remains in the body of the marker, rather than following the reg. You need to remove the plug that holds the PCV in place above the reg, clean the PCV, the plug and the cavity that the PCV sits in, and see if that resolves the issue.

I don't have a Geo2.1 personally, and so cannot take pictures of the PCV I'm afraid.

Quite simply though, you unscrew the reg from the marker, and the PCV is inside the threaded stub that the reg was screwed on to.

I'm currently experiencing this issue. I have made sure the PCV is in place, and tried installing the original fitting with pcv, and I still have bolt movement during degassing the marker. Its not a full shot but bolt does move to the full forward position with a small release of air. I believe this may be caused by my ASA venting the pressure to quickly. I swapped out the stock ASA for a BL Cam drive with drop forward (blasphemy I know). I have tested with and without the PCV and it is undoubtedly needed, but does not completely stop the discharge issue.

Would changing the ASA also allow the pressure to vent out to quickly to allow the PCV to be fully functional?

I had the same issue on my Geo 2.1. PE tech's at the NPPL DC event fixed it by changing out the small spring behind the PCV. Hope this helps.

Unfortunately I'm using a Geo+, PCV is in the macro line fitting.

I am reposting in this thread. Also posted on the main board.

I have a GEO 2.1. Recently, after having it for 11 months and it shooting perfectly and very efficient with air ( at least 8 pods on a 68/4500), I came across something weird.

When I degassed the gun the bolt popped into the forward position. Now I've seen this happen before on a GEO2 and on another 2.1 and usually what I would do is to readjust/clean the spring in the PCV and that would solve the issue. So I tried to do that with mine. When I opened the PCV assembly I found a cracked rubber bumper situated at the tip of the PCV.

So I thought ok, I just need to get a replacement rubber bumper. I went to my local store and asked for it and the PE certified level 3 tech guy didn't know what I was talking about. I hadn't brought my marker with me so I couldn't show him. So I asked him to open up one of the display markers to show it to him. And there was no bumper there. He checked some other customers markers that he was servicing also and this bumper was not present.

Does anyone know what I'm talking about? Do some Geo 2.1s come with this bumper and some don't or is there a foreign object that somehow got into my gun that fits perfectly on the tip of the pcv?

Would appreciate if anyone could solve this mystery for me.

Thanks

Looks like a small o-ring. I do not have this so called bumper?
