Rise Armament 12005 Anti-Walk Pin Set Black Stainless Steel AR-15

The Rise Armament 12005 Anti-Walk Pin Set eliminates trigger and hammer pin migration in AR-15 platforms, maintaining consistent trigger performance shot after shot. This precision-machined upgrade addresses a common issue where standard pins gradually work loose during firing cycles, causing trigger feel degradation and potential reliability concerns.

What Makes This Different

Unlike standard mil-spec pins that rely solely on spring tension, these anti-walk pins feature integrated retention heads that physically prevent lateral movement. The black stainless steel construction provides superior corrosion resistance compared to standard carbon steel pins. Each pin undergoes precision machining to maintain exact tolerances, ensuring proper fit without binding in standard AR-15 lower receivers.

Key Features

• Integrated retention heads prevent pin migration during firing
• Black stainless steel construction resists corrosion and wear
• Precision-machined to mil-spec dimensions for drop-in installation
• Compatible with standard AR-15/AR-10 lower receivers
• No permanent modifications required to receiver
• Includes both trigger and hammer pins
• Tool-free installation and removal

These pins maintain consistent trigger performance across thousands of rounds, particularly beneficial for competition shooters and tactical users who demand repeatable trigger characteristics. The anti-walk design prevents the gradual loosening that can affect trigger reset and break consistency. Installation requires no special tools or gunsmithing, making this upgrade accessible for home installation.
