Regal Gauge Upgrade

Although sufficient I'd like to upgrade the gauge on my Daystate Regal. I'm looking for one that the increments are spaced out and use 70-80% of the gauge's face. I removed it yesterday to take a look at the threads at it appears to be the 1/8BSPP thread with a shoulder that seals with a doughty seal. The OD of the factory gauge is 23mm. The hole through the stock is just under 1". T3P found one that's slightly better but still not what I'm looking for. FX gauges are nice but the threads on the one I have are slightly different I think and it don't have the sealing shoulder. Here's what comes on the Regal. Any other Daystate shooters have different gauges.

The Regal uses a British Straight Pipe thread while the McMaster Gauges I have found use NPT thread. They are not interchangeable unfortunately.

I have found close to what you are looking for on AliBaba from China BUT minimum order is several hundred.

I have an Altaros regulator on one of my Condors that has a nice gauge that might work well but I do not see it as a separate item on the Altaros site and it only uses about 1/3 of the gauge face for the scale.

I cannot find ANY gauge that uses more than about 1/2 the gauge face as the scale.

At this point I think an FX gauge "might" do the job if a replacement could be secured although I only have 1 FX gun to measure the gauge.

Thanks Thermond, I have a spare FX gauge from when I had my FX500 regulated. It would probably work without and Doughty seal and just use Teflon but overall it would be too long and stick out past the stock about a 1/4". It's also a larger diameter and is too big for the stock's hole. I'll keep looking but might have to stay with what I have which is sufficient..
