The cut‑off (Part R260) is a small pivoting steel lever mounted on the left side of the lifter/elevator in Mossberg’s lifter‑timed semi‑automatic actions, where it controls the release of cartridges from the under‑barrel tubular magazine, prevents double‑feeds, times the delivery of a single round as the bolt cycles, and synchronizes feed timing between the lifter, bolt face, and magazine; it is a core feed‑control component in the 51M → 151 → 251 → 351 → 377 lineage.
