Adler HT-104 12 Gauge 18.5" 5-Round Semi-Auto Shotgun

The Four Peaks Imports Adler HT-104 12 Gauge 4+1 18.50" semi-auto shotgun is purpose-built for tactical professionals, law enforcement training, and defensive shooting applications. With an 18.5-inch barrel and compact footprint, this piston-operated platform delivers the reliability demanded in high-stress environments while remaining practical for home defense and range work. The Adler HT-104 represents a proven gas-driven action design trusted across military and civilian tactical communities for its consistency and durability under sustained fire.

Built around a 7075-T6 aluminum receiver—the same aerospace-grade alloy used in critical load-bearing military components—this shotgun achieves a balanced weight of 10.9 lbs without sacrificing structural integrity or recoil management. The piston-driven operating system isolates the bolt carrier group from direct propellant gas, reducing carbon fouling and extending service intervals compared to direct-impingement designs. A synthetic stock with an oversized rubber butt pad absorbs recoil and secures the weapon during rapid fire, while the 4+1 magazine capacity (four rounds in the tube, one in the chamber) provides sufficient firepower for defensive scenarios and tactical training exercises.

This configuration excels for operators requiring a reliable, low-maintenance platform suitable for entry teams, defensive coursework, and extended range sessions. The 18.5-inch barrel length strikes the critical balance between mobility in tight quarters and velocity retention for defensive loads. Whether you're training recruits, conducting home defense preparation, or building a duty-ready shotgun battery, the Adler HT-104's piston reliability and combat-proven ergonomics make it an effective choice for professionals and serious civilian shooters alike. Standard 12-gauge ammunition compatibility ensures logistical flexibility across ammunition suppliers and load types.
