Finally, after months and months of preparation, down falls and all kinds of head aches, I'm finally having my estate sale this coming weekend.

While the bulk of the proceeds are going to be used to get my truck fixed and most of the rest reserved so I can find another place to live.

I wanna FINNALLY convert my 2300.

I'm not going to rehash every detail about what I'm doing. Done that enough already.

Here's my quandry. After discussing this with our resident 22xx guru and creator of the franken discovery Smile

it was determined that I could very well swap out the stock valve with the one I'm taking out of my discover rifle. I would NOT have the issue about the gas tube potentially exploding because it was never machine stamped with the serial numbers.

Even though I have no intentions of modifying the valve, I do realize it will flow faster then the stock valve. So after a conversation with Ron over at Byran and Associates, I can get a gas tube cut down to any size I desired.

But then I started thinking about this. If I were do do that, I'd have to add in the valve block and the end block with adapter. This would reduce the inside volume or it's ablity to hold more compressed air.

As mentioned I'm looking to order a cut down discovery tube, and threaded for the fill adapter, which I will buy from them anyways. How or where can I place a guage so I know how much pressure I'm filling the tube with?

Thanks,

Jax

You need to use the Crosman Disco gauge block which goes inside the tube, drill a hole in your shortened tube and screw it through the hole into the gauge block.

I was afraid someone was gonna say that... Sad/Cry

I was thinking.... I was already going to purchase a scuba adapter from jdsaire. But then add the hose off the pump I got with my discovery to it. What if I were to add a Tee after the adapter, and screw the gauge in there?

If you are going to use a SCUBA clamp they already have a gauge on them.... You have to stop filling at 2000 psi and that gauge is what you use to make sure you don't overfill....

The problem is that without a gauge on the gun you won't know when it needs refilling.... Putting a tee on the fill adapter to hold a gauge and the male Foster would work but ugly....

I hadn't thought about that.... knowing when the rifle needs filling issue. Guess it's go with the guage and block as orginally suggested.
