Got low price on Amazon for the soft touch black version.  I already have .22 from 2013 converted to HUMA.  Problem ....the regs leaking out of box 🙁  It arrived with 200 BAR and I took 3 shots and let it set overnight now empty :(.  I am hoping it's just stuck and I can replace reg o'rings.  I now sooner or later I can get a Huub designed regulator.  I just wanna try it out NOW

Help need Reg MK 2 o-ring sizes to check my stash

Might just be the bottle O-ring as they are easily nicked upon screwing the bottle into the reg.

Easy enough to disassemble and clean out the excessive goop they usually pack in.  Just be sure to re-stack the B-washers correctly.  Hey, if that doesn't work, just pop for the HuMa reg!

Don't recall the reg O-ring sizes, but I know I have several in my stash.

its sitting upside down wit Krytox oil inserted via air bleed holes hoping it will drip down and free up stuck oring on piston.  Do you remember if o'rings were metric or AS586 standards??   The UK also has a BS standard no pun intended.  I have the reg from my other MK 2 around here somewhere

replaced wasted regulator piston oring with a 009 size 90D poly one.  Which way on factory reg adjuster raises pressure??  Clockwise IS higher or lower ??
