I had to raise hpr up to get it to shoot 280. in psp 21.5 it was chopping paint.(not barrel breaks). Took the parts out put my v2 parts back in turned the hpr down to 280 fps and shot a hopper of paint with no problems.Tried the parts in my friends stock legend with the same results. I think rutley has a great idea I jus dont think that all the parts match up.
put the parts back in and bottom out the hpr so its at 0psi, from there raise it until it chronos the correct speed. Due to how light weight these parts are, at the stock parts pressure, the pressure behind the value is most likely too great for the weight of the ram to overcome. Main reason most markers now actually have somewhat heavier rams/bolts. Lighter is not always better. especially for a gun that has no lpr. one of the reasons why the old timmies shot so well. you can lower the lpr pressure due to the weight, which decreases the felt kick when running 50-75 psi to drive the bolt. unfortunately with a legend, the lack of an lpr prevents any sort of tuning so in reality these parts might be too light to be beneficial. Now without testing them, i cant say for sure, but thats what it sounds like
