Mock-Up and close-up pics of components. These were made for reference so that I could obtain the measurements for my build.

Another completely different concept is the use of dual springs to allow clearance for a semi-auto hammer.
Auto sear lug - this must and will be removed before I build to ensure I meet the legal requirements.
Carrier. Note the chafe marks. Presumably these are from the rail and the ejection port rivets

Trigger assembly and original components. The housing is permanently riveted to the receiver.
