An A2 upper’s a classic AR-15 upper receiver featuring a fixed carry handle with integrated rear sight and a forward assist. It’s designed for traditional, military style builds and provides durable iron sights and a stable mounting platform. The A2 upper works with AR-15 lower receivers, standard barrels, bolt carrier groups, charging handles, hand guards, delta ring assemblies, gas tubes, and A2 front sight towers. It’s ideal for shooters seeking a reliable, time tested setup for target shooting, training, or retro builds.
