my dad is looking to upgrade the trigger on his rock river AR, but he says he's being asked if he has a small or large trigger pin.   how do we check that?

RRA uses a small pin. Colt was the only one to use the large pin and now they have gone back to the small as well.

Your trigger and hammer pins are "small".  That = 0.155" in diameter
