I did a search and couldn't find what I need. Sorry if asked before.
Am thinking about converting my 1903A3 to an A4 and do not know the process. Was hoping there is a checklist, or set of instructions, that detail all that is needed to complete the process. Am thinking there should be a step-by-step somewhere on the web.

What I have on hand is:
1903A3 SN 4,133,xxx
Weaver model 330 scope
Redfield JR S-special scope mount base 511141
3/4" split JR/SR scope mount rings, std rear/front, low height

I have no knowledge of what is involved. Any help would be greatly appreciated.
