Planning to build an SBR. I know for the Form 1 app you need barrel length, over all length and a few other key details.
I had planned to purchase a lower/upper set and sit on them while the paper work goes through. After reading the rest of the requirements do I have to have all the parts on hand so i can get these mock up measurements or do you have to buy pre-made?
thanks
