The ProMag Archangel AA127 Extended Length Monolithic Rail in Carbon Fiber/Polymer with a Black Finish is designed to enhance your Archangel AR556R or Ruger 10/22 platform with a rigid, lightweight forend extension that delivers reliable mounting flexibility and improved handling. Built from a durable carbon fiber/polymer blend and finished in sleek black, this extended rail provides a clean, free-floating upper surface that helps preserve accuracy by reducing unwanted contact with the barrel and stock areas. It features two Picatinny rails for attaching optics, accessories, or hands-on stabilization, while quick detach swivel studs allow rapid attachment or removal of slings without disrupting zero. The extended length and monolithic profile offer a stable platform for tactical setups or precision-focused field use, making it an ideal upgrade for shooters seeking enhanced accessory attachment options without adding unnecessary weight. Designed to fit compatible Ruger 10/22 configurations and Archangel-style builds, this rail integrates seamlessly with existing forend components, delivering a cohesive look and dependable performance in field, range, or hunting scenarios.
