The Del-Ton AR-15 Heavy Rifle Kit 20" Barrel 1:9 Twist brings together a complete upper assembly, A2 buttstock, and full lower parts kit to help you build a classic, rifle-length AR platform. The 20" chrome moly vanadium heavy barrel features M4 feed ramps, a 1:9 twist, A2 flash hider, and a threaded muzzle, all protected by a durable manganese phosphate finish.

This kit is ideal for shooters who want the feel and balance of a traditional rifle-length gas system for range work, training, or general-purpose use. Standard rifle-length handguards, an A3 flat-top forged 7075-T6 upper receiver, and mil-spec bolt carrier group provide a familiar, reliable foundation for your build. Del-Ton’s attention to detail in headspacing, test firing, and component selection reflects the manufacturer’s reputation for solid, dependable AR-15 parts.
