All external components are finished to resist environmental wear and corrosion, ensuring long-term operational integrity and consistent performance in diverse conditions.
Enhanced Safety
Equipped with Mossberg’s ambidextrous tang safety, the system provides intuitive and positive control over the firing mechanism. This design choice optimizes accessibility and ease of engagement for both right and left-handed shooters, enhancing operational security.
