Want to buy the TRIGGER ASSEMBLY for a Mini-14:, preferrably a newer one or at least compatible for a new 583(?) series. I just got an ProMag Archangel Precision Stock for my new Mini-14 and apparently the trigger housing needs to be modified. I do not wish to do this to my new OEM parts. However, if I find an extra at a reasonable price, I'm all in. If you happen to see this post and have helpful recommendations as well to contend with this issue, let me know.
