Stern Defense H2S Drop-In Trigger Green AR-10/AR-15 Platform

The Stern Defense H2S Drop-In Trigger delivers enhanced control and reliability for AR-10 and AR-15 platforms. This precision-engineered trigger system features a distinctive green anodized finish and drop-in installation design that eliminates complex fitting procedures.

What Makes This Different

Unlike standard mil-spec triggers that require individual component installation, the H2S arrives as a complete drop-in cassette. The self-contained design maintains consistent trigger geometry and reduces installation time to minutes rather than hours. Factory testing ensures each unit meets strict pull weight tolerances before shipping.

Key Features

• Drop-in cassette design eliminates complex installation procedures
• Green Type III hard coat anodized finish resists wear and corrosion
• Compatible with both AR-10 and AR-15 lower receivers
• Precision-machined components from aircraft-grade aluminum
• Self-contained unit maintains consistent trigger geometry
• Factory-tested pull weight for reliable performance
• Standard .154-inch trigger and hammer pin compatibility

The H2S trigger system performs consistently across temperature ranges and environmental conditions. Competition shooters benefit from the crisp break and short reset, while tactical applications demand the reliability of the enclosed cassette design. The anodized finish maintains appearance through extended use and frequent cleaning cycles.
