THRESHER
Single-Shot Z-Shell Launcher
Description
The Thresher is a single-shot launcher built around the Z-Shell turn-lock mechanism for fast reloads and adaptable ammo types. Its sealed-shell interface allows reliable performance while enabling quick swaps between standard Nerf darts, Mega, Mega XL, and Rival formats without altering the core build. A shell holder attachment supports staged reloads, and the lightweight construction keeps operation simple while remaining competitive.
