I have cleaned it and I tried T8 - AG - and the old org piston seal, feels about the same.
I also think it's bad in cold weather below 10 degrees, even my WE feels more snappy, it shoots, but just not as I think it should.
buffer moly greased, what is that?
Regarding the piston seal, shouldn't i get pressure when I hold my fingers on the holes and push the piston in, because it doesn't regardless of which nozzle I have in and I've also changed the small o-ring at the bottom
