These are digital files for 4 different Kronos replacement plunger rods. One of them is exactly the same as the stock one, and then there’s three others with progressively shorter priming lengths. These are mostly intended for Kronomags if you want to be under a 150fps or 130fps cap. These should be paired with shorter barrel lengths (15, 10, or 5cm) depending on the chosen plunger rod.
