An AR-15 pistol barrel is a short barrel built for compact AR-15 builds. Most range from 7 to 10.5 inches and work with pistol-length gas systems. Daytona Tactical carries AR-15 pistol barrels in popular calibers like 5.56 NATO and 300 Blackout. These barrels fit standard AR-15 upper receivers and are great for home defense or range use.
