Tapco TAP22057 Anti-Walk Pins AR-15 Platform Black Stainless Steel

The Tapco TAP22057 Anti-Walk Pins eliminate trigger and hammer pin migration in AR-platform rifles, maintaining consistent trigger performance and preventing costly malfunctions. These precision-engineered pins replace standard trigger and hammer pins that can walk out during extended firing sessions.

What Makes This Different

Unlike standard mil-spec pins that rely solely on spring tension, these anti-walk pins feature enlarged heads with hex socket drives that prevent lateral movement. The black stainless steel construction resists corrosion while maintaining the strength needed for high round counts. Installation requires no permanent modifications to the lower receiver, preserving the rifle's original specifications.

Key Features

• Prevents trigger and hammer pin migration during firing
• Black stainless steel construction for corrosion resistance
• Hex socket heads allow easy installation and removal
• Compatible with mil-spec AR-15 and AR-10 lower receivers
• No permanent modifications required to receiver

These pins perform reliably across all shooting disciplines, from competitive shooting where consistent trigger pull is critical to duty applications requiring absolute reliability. The stainless steel material withstands harsh environmental conditions while the black finish reduces glare and maintains a tactical appearance. Competition shooters particularly benefit from the consistent trigger feel that comes with eliminating pin movement.
