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

The Stern Defense H2S Drop-In Trigger transforms standard AR-platform rifles with a crisp, consistent trigger pull that reduces reset time and improves accuracy. This single-stage trigger system delivers reliable performance across AR-10 and AR-15 platforms without requiring permanent modifications to the lower receiver.

What Makes This Different

Unlike mil-spec triggers that often exhibit creep and inconsistent break points, the H2S features precision-machined components that provide a clean, predictable trigger pull. The drop-in cassette design maintains proper hammer spring tension while eliminating the guesswork of individual component installation. Factory testing ensures each trigger meets strict pull weight tolerances before shipping.

Key Features

• Single-stage trigger system with consistent 4.5-5.5 pound pull weight
• Self-contained drop-in cassette requires no permanent receiver modifications
• Precision-machined steel components with anti-walk pins included
• Compatible with both AR-10 and AR-15 lower receivers (.154" trigger pin holes)
• Green anodized aluminum housing for corrosion resistance
• Reduces lock time compared to standard mil-spec triggers
• Includes detailed installation instructions and required hardware

Range testing demonstrates improved shot-to-shot consistency, particularly beneficial for precision shooting and competitive applications. The reduced trigger reset allows faster follow-up shots while maintaining safety margins required for duty use. Weather-sealed construction protects internal components from moisture and debris during extended field use.
