I reached out to Julie at SPA today to see if I could get the exploded view for the M16/ Dominator. She sent this to me in less than 12hrs.... To answer my own question about how power can be adjusted, looks like part 41 is a hammer spring adjuster. This and maybe a little tweak of the reg should be all that's needed
Sadly, all the hub-bub at the tradeshows earlier in the year were focused on the same old stuff. Very few of the YouTubers covered anything from the SPA booth.... despite SPA having a rifle with the air-tube surrounding the barrel. I'll keep on sending SPA my business since they build lightweight, powerful, accurate, and inexpensive airguns.Hooray Mike/MRodAir for picking up the M-16/P-15.
Here is one for the cp1from a British site.
For every gun made? Probably not gonna happen. Maybe something could be added to the Library though.
