The Stag Arms STAG-15 M4 is a no-nonsense 5.56 NATO AR-15 rifle built to mil-spec standards for hunters, sport shooters, and anyone who wants a proven platform without the frills or the premium price tag. This 16-inch carbine delivers the reliability of a military-proven design in a compact package that handles well in the field or on the range. The direct impingement system, chrome-lined barrel, and mil-spec components mean this rifle was engineered to run hard and last—exactly what you need when performance matters.
Stag Arms has equipped the STAG-15 M4 with genuine mil-spec hardware throughout: a forged 7075-T6 aluminum receiver with Type 3 hard coat anodizing for durability, a carbine-length gas system, and a manganese phosphate-coated M16 bolt carrier group that's built to handle thousands of rounds. The 16-inch 4150 steel barrel features a 1/7 twist rate and government profile, suitable for a wide range of 5.56 and .223 ammunition. You get a removable A3 carry handle and F-marked A2 front sight, so you can run it as-is or upgrade to modern optics and rail systems down the road.
Out of the box, this rifle comes with a 30-round magazine, six-position adjustable stock for length-of-pull customization, thermoplastic handguard with double heat shields, and an A2 birdcage flash hider. At 6.75 lbs, it's light enough for extended hunting trips yet substantial enough for serious marksmanship. The trigger is a mil-spec single-stage unit paired with a Magpul MOE trigger guard—nothing fancy, but predictable and reliable.
