The Stag Arms .223 Remington AR rifle with 16" barrel in Flat Dark Earth finish is a well-balanced, purpose-built modern sporting rifle that handles equally well for home defense, range work, or general-purpose shooting. Built on the proven Stag 15 platform with a direct-impingement mid-length gas system, this rifle brings together quality components and thoughtful ergonomics to deliver reliable performance without unnecessary complexity or weight.
At its core sits a Ballistic Advantage Hanson-profile 4150 CMV barrel with a nitride finish, threaded 1/2x28 for muzzle devices and topped with a VG6 Delta flash hider. That barrel profile strikes a real middle ground—responsive enough for rapid fire, stiff enough for accuracy, and light enough that you won't feel it in your hands all day. The Stag Slimline 13.5" handguard in 6061 aluminum keeps things trim while offering M-LOK mounting at the 3, 6, and 9 o'clock positions, plus a full-length Picatinny rail on top for optics or accessories.
Control-wise, this rifle assumes you might be left-handed or just prefer things set up differently. The Breach ambidextrous charging handle and fully-configurable ambidextrous safety selector let you work the gun from either side without contorting yourself. The trigger—a Hiperfire RBT single-stage—breaks at 4.5 pounds with a crisp, predictable reset that feels like a real upgrade over mil-spec. Furniture is from Magpul: MOE pistol grip and MOE SL stock for real-world comfort and adjustability. It ships with a 30-round Magpul PMAG Gen M3 magazine.
The FDE finish gives it a modern, practical look that works whether you're at the range or in a hunting camp. This is a rifle built to work, not to look expensive.

Yes. The 16-inch barrel and mid-length gas system give you a well-balanced rifle suitable for home defense, hunting, or recreational shooting. The lightweight Hanson-profile barrel and compact handguard keep weight down while the full-length Picatinny rail and M-LOK slots let you mount optics and accessories as needed.
Absolutely. The rifle features a fully-configurable ambidextrous safety selector and an ambidextrous Breach charging handle, so left-handed and right-handed shooters can manipulate the controls without changing their grip or cheek weld.
The rifle comes complete and ready to shoot, including a 30-round Magpul PMAG Gen M3 magazine and the VG6 Delta flash hider already installed on the threaded barrel.
The rifle ships without iron sights or an optic. The full-length Picatinny rail on top and M-LOK slots on the handguard give you plenty of mounting options for a red dot, magnified scope, or backup irons—whatever suits your intended use.
