You can change the insert in the harvester for 5/8×24, 1/2×28, 18×1, 9/16×24 RH, 1/2x32, or 7/16x28. You choose one of the first 4 to come with the harvester. Then extra thread inserts are around $70-80 each.
It is far more important to be able to hit the target than it is to haggle over who makes a weapon or who pulls a trigger.
