Rise Armament RA-140 Super Sporting Trigger Black/Red Flat AR-15

The Rise Armament RA-140 Super Sporting Trigger delivers consistent 3.5-pound pull weight with a crisp break that enhances accuracy for competitive shooting and precision applications. This drop-in trigger system features a distinctive black and red anodized finish with a flat trigger face that provides improved finger placement and control.

What Makes This Different

The RA-140 incorporates Rise Armament's anti-walk pin design that eliminates trigger pin movement during firing cycles, maintaining consistent trigger geometry shot after shot. Unlike standard mil-spec triggers with 6-8 pound pull weights and gritty breaks, this unit provides a clean 3.5-pound pull with minimal overtravel. The hardened steel components undergo precision machining to tolerances within 0.001 inches for reliable function.

Key Features

• 3.5-pound single-stage trigger pull with crisp, clean break
• Anti-walk pin system prevents trigger pin migration
• Flat trigger face design improves finger contact and control
• Black anodized housing with red accent components
• Drop-in installation compatible with standard AR-15/AR-10 lower receivers
• Hardened steel construction with precision-ground contact surfaces
• Minimal reset distance for rapid follow-up shots

This trigger system performs consistently across temperature ranges from -40°F to 160°F, maintaining the same pull weight and break characteristics. The reduced pull weight and clean break enhance accuracy for competitive shooters, while the reliable reset supports rapid-fire applications. Law enforcement and military users benefit from the consistent trigger control in high-stress situations.
