Product Details
If you're building your first AR or upgrading an upper, this Sons of Liberty assembled upper is a solid choice. It comes ready to pair with your lower receiver, features a 14.5-inch barrel threaded for muzzle devices (1/2x28 thread pitch), and handles 5.56 NATO rounds. You'll need to add a bolt carrier group and charging handle separately, but that gives you flexibility to choose pieces that feel right in your hands. The matte black finish is durable and doesn't show fingerprints like shiny finishes do.
