TPAK Re-Stack Ammo Cartridges.
Engineered for the lowest cost per round, ideal for high‑volume or ongoing training programs.
Each Re‑Stack package includes pre‑filled cartridges, Re‑Stack Tubes, and CO₂ cylinders, giving every cartridge up to 10 total uses under normal training conditions. This allows users to dramatically reduce long‑term training costs while maintaining the performance and reliability of the UNIT4 system.
To refill a TPAK Re‑Stack Cartridge, customers use the TPAK Re‑Stack Assembly Kit, which provides all tools required to safely and consistently reload cartridges throughout the life of the UNIT4 Rifle.
