Have two Armalite NM triggers for large pin Colts.
Don't see them on Armalites site but the standard lists for $180.
Never installed one is in platic wrap the other I took out but never installed.
Have these on two of my AR10's and they run real well. Reliable.
$150 $135(each) shipped (obo). Or trade for an S&S E carb or
other Harley Parts.
