UTG PRO AR Pistol Receiver Extension Tube – AR-15 Pistol Builds

The UTG PRO AR Pistol Receiver Extension Tube provides a reliable foundation for AR-15 pistol configurations. Designed to accept pistol braces or buffer tube accessories, this extension tube offers a sturdy mounting point while maintaining compliance with pistol build requirements. The precision-machined design ensures proper buffer and spring alignment for consistent cycling.

Constructed from high-grade aluminum with a hard-anodized black finish, this receiver extension tube resists wear and corrosion. The mil-spec threading ensures compatibility with standard AR-15 lower receivers and castle nuts. Installation requires basic armorer tools and follows standard AR-15 assembly procedures. This is a buffer tube only and does not include buffer, spring, or brace.
