- Caliber: .223 Remington, making it compatible with the widely available and versatile .223/5.56 NATO ammunition. This common caliber ensures easy access to ammunition and components.
- Barrel Length: 18 inches, providing an excellent balance between maneuverability and ballistic performance. The added length over a standard 16″ barrel contributes to increased muzzle velocity and improved long-range accuracy.

- Barrel Profile: Government Profile (Govt.), a standard barrel profile that balances weight and rigidity. The government profile is a good compromise for overall performance and handling.
- Rifling: Button Rifled, a proven method for producing accurate and consistent rifling. Button rifling generally offers a good balance of accuracy and cost-effectiveness.
- Additional Features: Threaded Muzzle, allowing for the attachment of various muzzle devices such as flash hiders, compensators, or suppressors. The threaded muzzle enhances the versatility of the barrel.
- Color: Black, a standard finish that is both aesthetically pleasing and functional. The black finish provides corrosion resistance and blends well with most AR-15 builds.
These specifications are crucial because they directly impact the rifle’s accuracy, reliability, and overall performance. The 18-inch barrel length and 1:7 twist rate, combined with the rifle-length gas system, contribute to a smooth shooting experience and the ability to effectively stabilize a wide range of bullet weights.
