An updated parts list is below!
Since I bought the parts for this gun some things have changed. Schuyler Arms is where I bought my builder set but they no longer seem to stock Aero Precision or Ballistic Advantage. That might change, so if you are looking at prices be sure to check http://schuylerarmsco.com just in case they come back in stock.
Monmouth Reloading has rebranded itself as Arm or Ally at https://www.armorally.com/.
