Before you get excited, shipping to the U.S. looks like it's going to be 59 Euros... At least, that's the rate when you click on "All Other Countries"... I'd wait for either a supplier here (hopefully there is/will be one), or maybe check Aliexpress for one... I'd love to get one of these for my .357 Brod though... Although, an adapter would have to be made... I just noticed the threads...
A coupe of years ago I got a externel regulator adjustable up to 250 bar: https://www.krale.shop/en/regulator-charging-kit-ks-inline-mk2.htmlWorks great, after changing the blead screw.
John, from the photos of your regulator, it looks like the adjustment is done by turning the screw inside the input end.... necessitating removing it from the tank to adjust.... It further looks to be quite large in diameter, and having DIN tank threads on both ends.... Further, I assume it require changing the Belleville washers (or a spacer) inside to go from "Low" to "Medium" to "High" range?.... Are those assessments correct?....Bob
Huma announced it they will have in sales regulator with G1/2-14& M18x1.5 threads next week...
That is the standard adjustable regulator available on eBay as well.... https://www.ebay.ca/itm/Regulator-6000-PSI-2-gauges-scuba-compressor-paintball-bauer-mako-coltri-eagle/181541288614 …. they are quite large, those are 2.5" gauges....Bob
