Umarex Gauntlet 2 o-rings

I've got a question. Are the o - rings that are found inside of the regulator of the gen 2 in 22 , 25 and 30 cal the same size o - rings? Thanks in advance Mr. Hajimoto.
Because Umarex used two different regulator manufacturers for the Gauntlet, they are not interchangeable. But if you have a Gauntlet 1 .22 and a Gauntlet 2 .25 and the regulator is from the same manufacturer, yes they would use the same o-rings.

I like very much how the spring washer stack in the regulator is held in place by the O ring at the top of the stack. The shims are easily switched to adjust the regs power output. I was able to find a shim at a local hardware store that has enabled me to shoot a 28 grain slug at 893 fps in my .22 cal. SL Thanks for all your informational videos on everything , and I can't wait to use the Buck rail Haji receiver (as I call it) for the Tactical look that I already have purchased from you. The main reason I purchased my 22 SL was for that 281/4" barrel. I was was disappointed to find a 231/2" barrel was the true length. I was looking at some TJ's airgun barrels , and was wondering if you ever re barreled any of your Gauntlets. I would love to see what it could do with a 32" barrel. OV.
