Career 707 Single tube - Is this a Regulated Gun ?

[ichy]

I just purchased this Career 707 single tube carbine with a small leak. As I degassed the air tube and heard the loud blast of air slowly diminish to zero, I then noticed that air would still be inside the tube every time I pushed on the hammer with my finger. So every time I opened the valve with my finger a puff of air would be expelled. This continued until the air tube was finally empty. Upon taking it apart I noticed it's not like the other countless Career's I've owned and repaid over the years. When I opened up the rear of the air tube I noticed what looks to me as a regulator. 

I don't want to continue to take it apart until I figure out what these parts are. Did Shin Sung ever make a regulated 707 from the factory ? If not, what kind of parts/set up is this ? Any help or lead would be appreciated. I'm baffled with this one. Thanks in advance.....

Whatever it is, that is one cool gun !

That is a cool gun. I had a .22 but I'm more a plinker so off it went. I'll follow this I would like to have another lever action.

I tore into it and it's not a regulator. I don't know what this mess is, how it works or what it's supposed to do. There is a piston with two O-rings and two other seals. If anyone can figure out what all these parts are supposed to accomplish I am all ears.

Looks like it seals for a removable air cylinder so you can carry extra air tanks .

This set up is not like the one they had on the Tanker carbine where tanks could be easily exchanged. To change the tank on this set up the gun needs to be completely degassed to get the air tube out. I feel it's some sort of pressure regulator but how is it adjusted ? Is it factory present for a country which regulates power output thus non adjustable ? 

Payramyd air was the only known importer of this gun so I've contacted them and hope they can solve this mystery.

ARS out of pine city NY imported these rifles maybe some one knows how to contact davis.

ARS might well be worth trying ( likely has good information) but he never Imported the last models of the career rifles.

I contacted Davis. It would be real cool if this in fact is a factory regged Career 707. I don't see any beveled washers but then some Ninja regs don't have washers but a spring. We'll see, someone has to know about this gun. It just didn't drop out of the sky....



Maybe the people at Ninja might know how this works....

Update.... The people I've contacted for clarification/information on this gun have never seen this set up before. One did suggest it "appear to be a regulator of sorts", that it may be "a prototype rifle as those look like Korean parts". I agree with him so last night I changed all the seals, put it together and gassed it up. This morning I checked and it's still holding pressure, so far so good. When I turned on my Chrony to get a shot string I realized I left it on last time I used it and killed the 9volt battery. I will pick a 9volt on my way back home from work tonight and see what happens. I hope I'm not boring anyone but I'm kinda thrilled to have stumbled across the only known Career 707 with a factory equipped regulator. If there are others out there please contact me.

interesting not boring. Love to see a shot string and some groups.

I have a few Career pcps but not this one. I've never seen anything quite like that inside. This is pretty neat.

I forgot to mention that in the chamber that houses the piston with two Orings is a hole that vents out. An air regulator vent hole ? I hope so... The theaded hole seen in this picture is to secure the wood hand guard. The small vent hole is on the opposite side of that.
