For one, the design has you NOT tighten the parts completely until valve is inside the air tube & secured.  Then with a long tool that fits the end cap tighten the parts together which crushes the o-rings slightly.   I do these all the time and just always grab the correct o-ring matched up from my large selection.  IIRC the rings are Metric 2.5×22's Buna/n 70 duro.

 

** hope someone else can confirm the size tho …

 

PS.  See those TWO odd marks on mid tube ? … those are from the receivers Forward anchor screws bottoming out against the valve. Shorten the screws .020" or so and the receiver will be more secure and accuracy likely better too.
