Here is the start of a new build the barrels in the pic are 24" long one is .177 and the other is a .22 also two choices on the valve both are from BA a boss valve and a bulk fill set up.I ordered two 2250B tubes.

Wow !

Is part of that Hi-Pac? keep posting...you have our attention.
BTW: Go for the Boss Valve :)

I had recently took inventory of all the take off parts in bins and had enough to build a 2250B except for a tube and cap.
All bone stock parts. I like it because it seems like it was a free gun...except for the air tube and cap of course.
I guess a very cheap gun.
-
Nice! Cant beat a free gun. And i 2nd Walts question, is that going to be a pcp of sorts? Keep us posted on how it works out.

Yeah i think im going with the Boss and use the bulk fill set up on my 2260.

Will the boss valve hold up to the pcp ? i need a gauge also.
-
That makes 3 of us looking into that question. I was looking at it for my 2250 also.
-
That's why I would go with the Disco (Mod'd) Valve and the Gauge Port etc etc.....
It just depends on what you want in the end...i.e.Carbine...?

I just emailed. Rookedbarn and bryan to ask if they knew weather their valves would reliable hold up to the 3000 psi.

DJ,...... :) Remember, Disco tubes are at 2000PSI... Unless you are using a DC - SS I wouldn't push it. :)
Although...the 2260 is probably good to 6000... :) You didn't hear that from me. :)

Good point Walt i keep forgetting to put in here i have a hipac pcp conversion the feeds straight to the valve and is designed to go up too 3000 psi. The end of the hipac is shaped like a co2 cartrige so it just screws into the gun where the cap screws onto the gun and delivers the air right to the valve, no pressure on the tube. I just have to figure out if the boss valve can handle that high of pressure.
If your running a bulk fill the relys on the tube of the gun to store air don not over fill it! A 65 psi tire popping can pop your lungs, imagine 2k+ next to your head. Be careful all and dont go over the suggested pressure ratings!
As soon as i get an answer on weather the valves can handle the pressure ill post it here!

DJ,
This is from B&A's site: Max-Flow Valve
Max-Flow Valve: The Max-Flow valve face seals the tube allowing Bulk-Filling.
The tapered passage directs the increased CO2 capacity directly to the Boss valve.
A standard valve below for comparison. For 2240, 2250B, 2260, 1760, 2300, 2400

I think this runs along the lines of what some here are trying to achieve: Disco Pistol (3 screw pinned valve & Disco shortened tube)

Nice rig Vet ;) I think i will stick with the Boss valve this was i can change back to a 12g cart. I think i might Gun kote the tube and frame and or the breech, the wheels are still turning.I want this build to be like no other.Anyone no where to get a full wood stock for the 2250s ?

You could probally use a 2260 and shorten the end a little (just slightly).
I will have one available very soon. Let me know.

Mike, With the 2250 tube, to go a wood full rifle stock, you would have to change the trigger group to a 2260 or Disco Assy. Just FYI

Oops my bad lol i just need the rear stock like the 1399 stock but solid wood no hole. I just might try to make one myself.

Hi Mr. Myers, Thank you for Emailing. Your question is a good one. I have never used the Boss 12-gram valve with pressures of 3,000 psi, so I can't say with certainty. The walls of the valve are thinner than the walls of the stock valve, so my answer would be no. The valve has not been tested at that high a pressure. We recommend no more than 1,200 psi.
Here is the reply from crooked barn in ragards to hpa and the boss valve! Not advised by the guy building so i would not try it.
-
Thanks for the update DJ....... :)
-
Thanks ! we cant discuss this in the crosman benjamin airgun gate section what a joke.

I have used the co2 boss valve up to 2000 psi. made over 20 fpe with kodiaks.

Dave, I think some wires got crossed in the conversations. Yes, I agree with Boss @ 2KPSI

Thats good news i now need to order a guage. Where did you get your gauge.

Mike,
I use the fill gauge on my great white 88cf tank. I have a couple of 22xx projects on the fire. Just got a couple of 13ci tanks for my AS2250XT is one. The other that uses the co2 boss valve is documented a little here http://www.airgunsforum.com/showthread.php?p=352#post352 (http://www.airgunsforum.com/showthread.php?p=352#post352) Notice the shot string at 2K psi. Its pretty efficient.
