Watchtower Firearms RDR556-16-FDE Raider 5.56 NATO 30+1 16" Black Nitride Flat Dark Earth Cerakote Barrel, Aluminum Receiver w/Picatinny Rail, Adjustable Black Polymer Stock, B5 Grip, Ambidextrous
The Watchtower Firearms RDR556-16-FDE Raider is a 5.56 NATO carbine built for shooters who need a compact, reliable platform that doesn't sacrifice control or accuracy. At 16 inches, the barrel strikes a practical balance—short enough to handle in tight quarters, long enough to deliver velocity and sight radius for precision work. Whether you're running drills at the range, training for defensive scenarios, or just putting rounds downrange, the Raider gives you a straightforward, no-nonsense AR-pattern rifle that does what you ask of it.
The Raider comes dressed in Flat Dark Earth (FDE) Cerakote finish on a black nitride barrel, a durable combo that works across varied terrain and doesn't scream for attention. The aluminum receiver is topped with a Picatinny rail for mounting optics or accessories, and the ambidextrous controls—including a B5 grip and adjustable black polymer stock—let both right and left-handed shooters operate the rifle intuitively. At 6.5 pounds, it's light enough to handle all day without fatigue, yet solid enough to inspire confidence in its construction.
The 30-round magazine capacity means longer strings of fire without a reload, and the rifle ships with one mag, an owner's manual, and a safety lock. Standard AR-15 aftermarket parts and accessories will fit, so if you want to customize or upgrade down the road, the ecosystem is huge. This is a working rifle for working shooters—no hype, just functionality.
