Forster DIE-G-20 Accu-Ring Die Lock Ring Sizing/Seater Tool

The Forster Accu-Ring (DIE-G-20) is a die lock ring for sizing and seater dies that features reference marks graduated in 0.001" increments, allowing reloaders to precisely dial in case headspace length and bullet seating depth. Its thousandths-of-an-inch graduation markings set it apart from standard lock rings by enabling repeatable, fine-tuned adjustments without guesswork.
