B Staley mod - can someone briefly summarize? Somehow I’ve got it in my head that this is the same as the airforce o ring - behind -the -top-hat-trick - is that correct?
All testing was with NSA 61.5 .3033250psi0 turn 732 fps+3 turn 868 fps3500psi0 turn 732 fps+3 turn 836 fps+4 turn 891 fps = 108.4 fpe😁String #1+3 on hammer spring3500psi to maybe 2700psi9 shots817 fps low to 881 maxString #2+4 on hammer spring3500psi to maybe 2800psi5 shots870fps low to 890 highThat's a 2.2 ES over 100fpe 😁😁😁😛😛😛So,It looks like the gun can be tuned from 70fpe to 108fpe with the transfer port open at max.Very happy with the results. Still a little nervous about the resin printed spring guide but it seems to be holding up. For a working prototype, it's doing good. I think I will change the 8/32 adjustment screw to a 10/32 later and make it a knurled screw so it can be adjusted without a wrench.Good times. It's been such a long time that I worked on guns due to my situation, I forgot how much I liked it.
I think a bit more hammer spring would flatten that small curve out. You mentioned experimenting with some springs yet, that or a washer or 2 would bring that curve flat.
