Wellllll, this is there under "tutorials" where you mentioned to look on the home page -- "Build The 1919a4 Semi-Automatic Weapon: A Picture-based Tutorial" (where, about half-way down, along with a picture of a rivet set, it mentions "Note: Refer to 'a riveting guide' referenced to on the home page of 1919a4.com prior to riveting. Familiarity with this will simplify the process."
No 'riveting guide' or other tutorials there. There is some riveting help as one moves down in the tutorial, but there might oughta be a separate guide which goes over it all, pros and cons of tools, presses, cold forming, availability of tools, rivet sets, forming domes, invisible setting of rivets, and ....
Carry On!
