PGI Osiris

Okay, I need all the info I can get on the way these markers operate. Specifically the front block. I know they use a second LPR to reduce the pressure of the return stroke of the ram to incredibly low pressures, so as to pinch the paint instead of chopping it. But that's it. I don't have specs, pics, or technical info, and all that would be amazingly appreciated. I can't find anything over Google or any forum I've visited, and PGI went belly-up.

Basically, I've got a crazy idea for my Dark Cocker, and I need some help to make it work. Thanks for anything!

Edit: NVM! I've got another idea. SEEECRIT!

They used a 5 or 6 way instead of a 4 way valve.

Thats the real ticket to making one ram operate off of 2 LPR's I think.

Otherwise, they are just a cocker and they even sold the front block with their 6 way valve.

We had a pgi sponsorship for a year, the osiris indeed uses a 5 way. They are basicly a very fast autococker.

There was alot of talk awhile ago that you could simulate the effect using 2 2-ways. One for the forward stroke, with its own LPR, and another for the rear stroke.

They could still run off the same board, and same wire. Just have the 1st 2-way be a "Spring-open", and the 2nd be a "Spring-closed".

It could all be done with off-the-shelf parts.

I think that was someone else, Gemini perhaps? The mech 6 way with different forward and rear pressures. Definitely not PGI but I can't remember who it was.

The Osiris was different. Take a cocker and put a pneumatic hammer in the lower tube. Operates like an Excalibur but with a cocker body and back block. Then you can run dual LPRs and have the bolt pressure be different from the hammer pressure. They set them up both ways, not all had 2 LPR's. The ones with 2 LPR's were supposed to not chop due to the low bolt pressure. They primarily used Eblades.
