Im finding the cap on my RSST seals good,but the cap wants too come off if i just push on the side,its annoying.Im starting too like my AGAT2 better now,even tho the nut on the center post is hard too work with.
I had that issue with mine. I took the o-ring from a carto tank and put it on there. The cap is a nice tight fit now. Almost annoying when i have to take the cap off
