Del-Ton 20" Pre-Ban A2 Barrel Assembly

The Del-Ton 20" Pre-Ban A2 Barrel Assembly is a purpose-built upper receiver component designed for shooters and builders seeking authentic mil-spec performance in an AR-15 platform rifle. This barrel assembly serves law enforcement agencies, military personnel, and civilian shooters who demand precision and reliability in tactical and duty applications. The pre-ban configuration makes this assembly particularly valuable for compliance in restricted jurisdictions while maintaining full functionality and accuracy standards expected in professional and competition environments.

Built to mil-spec tolerances, the Del-Ton 20" Pre-Ban A2 Barrel Assembly features a chrome-lined bore and chamber designed to withstand high-round-count training cycles and extended duty use without accelerated wear. The 20-inch barrel length provides optimal velocity and accuracy for intermediate rifle cartridges, delivering superior ballistic performance compared to shorter configurations while maintaining maneuverability in tactical scenarios. The A2-profile design—a government-spec standard—ensures compatibility with standard AR-15 upper receivers and handguards, and the integrated A2 front sight base provides a proven aiming reference platform that has seen decades of service across military and law enforcement organizations worldwide.

This assembly is ideal for builders constructing compliant rifles, duty weapons, or precision platforms where barrel integrity and consistent performance are non-negotiable. Installation requires basic upper receiver assembly knowledge—the barrel, gas tube, and front sight base are pre-assembled and ready for mounting into a compatible upper receiver. Weighing 7.07 lbs and measuring 20 inches in overall barrel length, this assembly integrates seamlessly with standard mil-spec AR-15 components, gas tubes, and bolt carrier groups, making it a drop-in solution for those replacing worn barrels or building from a lower receiver.
