Special attention was given to incorporate smooth transitions throughout the rifle, giving it a feel of confidence and reliability. Weight reduction was made without compromising strength and integrity. The barrel weight savings alone can be up to 64%. All of this innovation is backed up with a life-time limited warranty. All of our weapon systems are 100% American made at our factory in the State of Montana.

Carbon Fiber Barrel:

These match-grade carbon fiber wrapped barrels were specifically designed and engineered for SI-Defense. These barrels aren’t just a light weight alternative to traditional steel barrels. These barrels provide superior performance, extreme accuracy, unprecedented durability, and increased barrel life. Reduced harmonic barrel vibration, improved heat dissipation, and no point-of-impact shift during high volume fire, is why SI-D put these barrels on its weapon platforms. They’re not just lighter-they’re better! Every barrel and weapon sold at SI-D is tested and proven before it leaves our factory.
