American Tactical's Milsport line delivers a complete AR-pattern build, and this pistol configuration pairs an 8.5-inch barrel with .300 Blackout in a black finish. That combination is not accidental: .300 Blackout was engineered specifically to burn its powder completely in short barrels, so it loses far less performance than 5.56 does when the barrel is cut down. Add subsonic loads and a suppressor and the platform becomes remarkably quiet. With an M-LOK free-float handguard and a flat-top upper, it is an easy foundation for a compact, suppressed, hard-hitting build.
