The Stoeger M3000 Max7 28" features a hunting‑oriented 28" vent‑rib barrel designed for consistent patterning and quick target acquisition; it’s typically chrome‑lined for corrosion and wear resistance, finished in a matte/blued surface, and fitted with a vent rib and bead front sight (often fiber‑optic) for fast sighting in the field. The Max7 barrel normally accepts interchangeable choke tubes, allowing you to tailor shot patterns to different loads and ranges, making it a versatile choice for upland and waterfowl hunting.
