New guy here, and thanks to Nikoum for providing the parts and schematics lists, it's much appreciated.
I've recently picked up a Notos, added a couple of cool pieces from Bravo 3D, mounted an Athlon Argos scope and after looking for the biggest bang for the buck pump ended up with a Spritech that did it's job fairly well. Anyway, after the first test firing and zeroing in, I packed everything away and the following day I set up for another session only to find that an o-ring was missing from the quick fill probe that prevented me from getting another session going. I was wondering if anyone here would know the sizes of the o-rings on it, specifically the pair of o-rings that seals that port that delivers air into the carbine's cylinder. When I tried measuring the single o-ring that was remaining with a digital caliper I came up with 7x4x1.5mm but didn't see the probe listed in the parts list Nikoum provided. Any help is greatly appreciated.
