I have a sporterized 30-06 springfield, and i wanted to buy a new trigger. I don't know what model it is, how do you tell them apart, from the 1903 all the way to the 1903A3, and i think there is a A4.
It is a 1903 Springfield. That is the model number. All 1903 Springfields use the same trigger. Buy a trigger for a 1903 Springfield and you are golden.
