The Rock Island X4 Tact LI-ON delivers reliable semi-automatic performance for tactical applications and home defense scenarios. This full-size 12-gauge platform combines proven gas-operated cycling with modern ergonomic features. The 3-inch chamber capability provides versatility across ammunition types from standard loads to high-performance tactical rounds.

What Makes This Different

The X4 Tact features a lightweight aluminum receiver that reduces overall weight while maintaining structural integrity under rapid-fire conditions. The pistol grip stock configuration offers enhanced control compared to traditional straight stocks, particularly during quick target transitions. The 18.5-inch barrel length meets federal requirements while optimizing maneuverability in confined spaces.
