The Del-Ton 20" Pre-Ban A2 Barrel Assembly is a complete upper built for shooters who want the classic AR-15 service rifle look without giving up real range performance. It pairs a 20-inch barrel chambered in 5.56 NATO with a fixed, non-detachable A2 carry handle and adjustable iron sights, so it runs as a standalone upper the moment it drops onto a lower. Builders restoring a retro configuration or assembling a first AR will find this is a straightforward way to get a known-good upper from one of our Del-Ton barrel assemblies rather than sourcing each part separately.
The 20-inch barrel uses a chrome moly steel construction with a 1x9 twist rate, an M4 profile, and a carbine-length gas system, per the spec data we have on this assembly. The 1x9 twist stabilizes a broad range of common 55- to 69-grain 5.56 NATO and .223 loads, which keeps your ammunition options open. The A2 upper carries a fixed carry handle with windage- and elevation-adjustable rear sight, giving you a full iron sight setup out of the box. The package also includes a high-pressure-tested and magnetic-particle-inspected bolt and carrier assembly, a charging handle, and carbine handguards, so the bolt group has already cleared inspection before it ships.
This upper suits a service-rifle style build, a 20-inch range gun, or a budget-conscious AR project where you supply your own lower. The fixed carry handle and longer barrel make it a solid choice for shooters who like irons and want every bit of velocity from a 5.56 NATO load. Because it arrives with the bolt group and handguards installed, you skip most of the bench work. Browse the rest of our Del-Ton rifle kits or compare it against other options in our complete uppers selection to match it to your build.
It ships as a complete A2 barrel assembly. That includes the 20-inch barrel, the A2 upper with fixed carry handle and iron sights, the bolt and carrier assembly, a charging handle, and carbine handguards. You supply a stripped or complete lower to finish the rifle.
The barrel has a 1x9 twist. That rate handles most common 5.56 NATO and .223 loads, performing well with bullets in the 55- to 69-grain range. It is a versatile choice for plinking, range work, and general-purpose loads.
Yes. The assembly includes a bolt and carrier group that has been high-pressure tested and magnetic-particle inspected, so the bolt has already cleared those inspection steps before shipping. A charging handle is included as well.
Yes. It is built on a mil-spec A2 upper and mates to standard AR-15 lower receivers using the front pivot and rear takedown pins. No additional fitting is typically required to assemble the rifle.
The Pre-Ban label refers to the classic A2 service-rifle configuration with a 20-inch barrel and fixed carry handle. The 5.56 NATO chambering, M4-profile barrel, and full iron sight setup give it that traditional AR-15 rifle layout.
