What is the Sigm400 5.56 Nato Rifle 16In Classic Black Semi Tele Stock PL HG (1) 10Rd MAG CO HI IL MD? It is a semi-automatic, direct impingement rifle chambered in 5.56 NATO/.223 Remington with a 16-inch barrel, a classic black finish, and a telescoping stock. It ships with one 10-round magazine and is configured for compliance in states with capacity restrictions like Colorado, Hawaii, Illinois, and Maryland.
Key Features & Practical Value
Let’s talk bang-for-buck. The heart of the Sigm400 is its mil-spec compatible design. This isn’t just marketing speak—it means you have a vast, affordable aftermarket at your fingertips. Want to swap the pistol grip or handguard? Parts from brands like Magpul or BCM will fit out of the box, no gunsmithing required. That’s a huge value driver, turning this rifle into a platform you can customize as your needs and budget evolve.
The 16-inch barrel length is the legal sweet spot for a rifle without NFA paperwork, providing a good balance of velocity and maneuverability. The included telescoping stock adjusts to fit shooters of different sizes, making it a practical choice for shared use or finding your perfect length of pull. The 10-round magazine it comes with meets restrictive state laws, but the rifle itself functions flawlessly with standard AR-15 magazines where legally permissible. Weighing in at approximately 6.5 lbs unloaded, it’s a manageable weight for extended handling.
Here’s the thing—this rifle focuses its budget on the essentials: a reliable barrel, a properly heat-treated bolt carrier group, and a forged receiver set. You’re not paying for a fancy rollmark or unnecessary frills. You’re paying for a tool that goes bang every time you pull the trigger. The classic black finish is durable and low-maintenance, perfect for the practical shooter.

Pros & Cons
Pros: Exceptional value for a complete, ready-to-shoot rifle. Mil-spec compatibility unlocks endless customization. The 16-inch barrel is versatile for most applications. The compliance configuration makes it available to a wider range of shooters. It’s a simple, proven design that prioritizes function.
Cons: The included 10-round magazine is a necessity for certain states but may be seen as a limitation where standard capacity is legal. As a value-oriented rifle, the finish and some components may not have the same refined feel as a rifle costing twice as much—that’s the practical tradeoff.
