Yes, what are you trying to do? The only real 'tuning' you can do is with the hammer spring adjuster. I've made mine externally adjustable. JArmstrong is my go to expert.Anyone had any experience in tuning the sapsan
Yeah, no. They had mine for a year for a bad regulator, then broke it, they finally gave me a new one, turns out the barrel was bad, I had to buy my old barrel back. I was patient because it happened just when Putin invaded Ukraine.Here's a little info -

The hammer spring can be adjusted externally with some modifications of the stock and the HSA, which I've documented in another thread over a year ago.that video is of the original Sapsan, in my opinion , had multiple problems,
the replacement Sapsan S model, fixed the problems, I still have an original model in pieces in a box, I moved on and bought a used Sapsan S in the classifieds.
It had a couple of problems, I fixed them. sharp edges that cut o-rings during assembly and no taper to the barrel leade
On the S model, the adjustments are internal ,, hammer spring needs the stock removed to adjust and the regulator needs the tank drained and removed to adjust it
