Built on the AR-15 platform, this STAG-15 SPR uses a semi-automatic, direct impingement operating system. The lower receiver is marked "STAG ARMS CHEYENNE, WY USA," model "STAG-15," and "CAL: MULTI." The flat-top upper includes a forward assist, dust cover, and shell deflector with right-side ejection for dependable function and service-friendly features.
The 18-inch barrel is stamped "4150" and "1/7," providing a durable steel profile with a fast twist rate for a broad range of 5.56mm loads. A three-chamber, side-ported brake/compensator is installed and is pinned and welded, supporting a compliant-style setup while controlling recoil and muzzle movement.
A free-float aluminum M-LOK handguard offers mounting slots at 3, 6, and 9 o'clock with a continuous 12 o'clock Picatinny rail that carries a STAG ARMS badge. Controls are thoughtfully configured with an ambidextrous safety selector and ambidextrous-latch charging handle. The trigger features a curved shoe with an H mark on the face, and the pistol grip is Magpul.
The Magpul carbine-pattern stock is fixed (pinned) on a carbine receiver extension, yielding a 14.25-inch length of pull. Capacity is 10+1, and this rifle is identified as the STAG-15 SPR configuration in a compliant-style setup, aligning with requirements often seen in regulated states. Made in the USA and includes a 10-round Magpul PMAG Gen M3 magazine.
