Mechanical Specifications
The rifle uses a rifle-length gas tube with a 0.750 gas block finished in black oxide. The trigger breaks at 5.5 to 6 pounds—a clean, predictable release suitable for precision work. The included muzzle brake is designed for easy installation without thread-locking compound.
Practical Details
Overall length is 44 inches, and the rifle weighs 9.3 pounds—manageable for field use while the heavier profile supports accuracy. The rifle ships with one 5-round magazine and includes the muzzle brake. No sights are included, allowing you to select optics matched to your intended use.
