Vltor Receiver Extension M4/car15

The Vltor Receiver Extension M4/CAR15 is a precision buffer tube engineered for AR-15 platform rifles and carbines requiring reliable stock assembly performance in tactical, competition, and duty-use environments. This component serves as the foundation for collapsible stock systems, directly impacting ergonomics, weapon handling, and overall shooter control during dynamic shooting scenarios. Built by professionals for professionals, the Vltor RE-1 extension combines proven materials science with field-tested design principles that law enforcement and military operators depend on across extended operations.

Manufactured from 7075-T6 aluminum, the Vltor Receiver Extension M4/CAR15 delivers superior strength-to-weight performance while maintaining dimensional consistency critical to proper stock fitment and function. The five-position design provides multiple length-of-pull configurations, accommodating varied shooting positions, body armor thickness, and shooter preference without requiring tool changes. The matte black anodized finish resists corrosion and glint, essential for tactical applications, while the robust internal geometry ensures smooth actuation and positive detent engagement across the full range of extension positions.

The Vltor Receiver Extension M4/CAR15 is compatible with standard AR-15 buffer tubes and collapsible stock assemblies, making it ideal for builds requiring modular reconfiguration or replacement of worn components. Weighing just one pound, it adds negligible mass to the rear of the platform while providing the rigid support necessary for consistent cheek weld and sight picture repeatability. Installation requires no modifications to the lower receiver, and the extension interfaces seamlessly with both mil-spec and commercial buffer systems, offering flexibility for shooters building precision carbines or maintaining existing inventory.
