It seems almost impossible to find a Milazzo Krieger large pin 2 stage trigger for my Colt rifle.

I was wondering if there exists an "pin adaptor" for a large pin Colt rifle which would facilitate using a small pin 2 stage trigger (like a Rock River NM trigger) in a large pin lower receiver?

Has anyone tried to adapt a small pin trigger to a large pin lower receiver?

Is this possible?  Has it been done?  If so how?

Thanks much.
