the regulators only have one o-ring, Guilleru branded, they are the only ones that make a M18x1.5 for the carbon bottles, I got the regulator from Ebay, lot of listings there, the AR stock I got from PA, the rest I made myself, once I'm done with tweeking the fit and everything I can post the 3D files of the parts, I did not Modify the gun in any way, I may cut out the choke on the barrel, but nothing has changed on the gun so the original stuff can be remounted at any time.I have a thread going on it nowhttps://www.gatewaytoairguns.org/GTA/index.php?topic=183845.msg156104112#msg156104112

I contacted them asking if it will fit the Gurlleu 30 cu tank:https://www.ansgear.com/Ninja_Ultralite_Adjustable_Tank_Regulator_4500_P_p/ninjatank-regul45.htmJust found the Gurlleu tank on Amazon with no regulator (). $300, the Ninja regulator is $55. $350 + $300 Gauntlet rifle + stock and other matters-upgrades like the band, shroud or barrel, you are already in your way to $700 +, not counting a good scope, bipod, suppressor system (if added)... Unless you are just interested in building your own version, with all that money you may get a better quality system. But as you have the 3D printer indeed may save some, though I was talking about the breech type of quality built, etc.
30 cuFt is way to big, that's almost a full size SCBA tank, 500cc tank they have for $199 without regulatorthe diameter is 2.39 inches, length is 11.75 inches, it uses a M18x1.5 Regulator. the Ninja Regulator is the best but they don't have them in M18x1.5, plus I'm on a budget so the $20 Guilleru regulator will work for me. I have the tank and gun pressurized to 3000 psi right now, leak testing, so far it's holding pressure... my fore grip stock is still on the printer, 80% done, it should be done around 11 pm, I hope....
Just going to mention how many 200 shots really is….it’s more than you want to get serious about shooting at one sitting. Getting 200 shots in a row with good concentration isn’t often needed….even in testing, I seldom do it.Can estimate in with regulated rifles, that should use a proportional amount of pressure...but actually sitting down and trying for groups wears pretty thin by about shot #70 or so. Past that, it’s like plinking….concentration just can’t be a good by the 199ths time.So the main idea is to fill once, and set it aside for several sessions. May be weeks or even a month between shooting sessions. So long as it’s sealed up tight and doesn’t leak, doesn’t really matter how long it takes you to shoot the 200 shots.So anyway...someplace about 205 shots, it went off reg and the last two 5-shot groups show a bit of drop.
the Guilleru reg doesn't come with a shim kit, you would have to buy them from https://www.mcmaster.com/belleville-spring-washers/I'm not worried about the o-ring, I've got a bunch of them if neededthe fore stock came out a little warped, the masking tape bubbled up and since it's been cold at night, it warped a little, but that's ok, I can make a new one later, this one will work just for fitting.

Does it have two parts that make one? I see a line close to the center.I found on eBay same type of tank for $138 + $10 shipping. Just looking around for now:https://www.ebay.com/itm/Paintball-4500psi-0-5L-Air-Tank-M18x1-5-Threaded-CE-Carbon-Fiber-Cylinder-300Bar/164640053910?hash=item26554fda96:g:yjcAAOSw3lJf~Wr3What size (thickness) did you use on each shim you added?
I sold my Bullboss .22 to a friend, I still have a Bullboss .25, both guns are regulated, I like the .25 bullboss, it's got a good punch to it and it's very accurate, I have it tuned to 900 fps, I get about 25 good power shots from it before needing refill, I could tune it down, but I want it at this power for Coyotes....

I was telling you about the suppressor, not the Bullboss.Just ordered the Gauntlet .25...now all it starts again!
just finished the exterior mods to the Gauntlethere it is, it has lost over a pound in weight, 7.8 lbs with scope
