A 5.56 NATO pistol is a compact AR-15 platform firearm chambered in 5.56 NATO, featuring a short barrel (typically under 16″) and designed for maneuverability and close-quarters use. It works with AR-15 pistol lower receivers, 5.56 barrels, upper receivers, bolt carrier groups, pistol buffer tubes, handguards, gas systems (often pistol or carbine-length), and standard AR-15 magazines. This setup is popular for home defense, tactical applications, and range shooting, offering rifle performance in a compact, easily handled package.
