If the valve swap doesn’t work, the only thing i can do … not to fix it but prove theres a issue. Swap the barrel/mags on both with each other.
i really believe it has something to do with the closing valve assembly. It does what it’s supposed to do allowing more air to pass as tank psi lowers but sooner than it should.
It operates great 35 down 30, slowly increases per shot till about 25 mpa before it opens up.
If i run it at say 20 fpe with a 30 fill it will do great 30 down to 25. Then spike at 20 mpa.
I dunno, ive had 3 different springs in there, no difference.
Up top … 3 valves. 2 strikers and multiple different springs… no difference.
Maybe something machined off within the block. Swapping the barrels will tell me a lot.
