Our handguns undergo rigorous test firing at the factory to verify function, extractor strength, and sight alignment before packaging. This guarantees that your firearm performs straight out of the box.

We source our raw polymer and high-strength steel from certified aerospace suppliers who prioritize structural purity. This ensures that every receiver resists cracking under heavy firing schedules and thermal load.

The gas system in our rifles utilizes a short-stroke piston design that keeps hot gases and carbon residue away from the bolt carrier. This leads to a cooler running action and less cleaning downtime.

Our quality control managers check barrel concentricity, chamber dimensions, and head spacing on every single build to maintain tight accuracy tolerances. We believe in providing operators with complete battlefield reliability.

The receiver features a durable hard-coat anodized or flat dark earth finish that resists moisture, sweat, and salt spray. It is built to survive in freezing rain, muddy trenches, and desert heat.

With our modular buttstock system, you can adjust the length of pull and cheek riser height in seconds. This allows you to fit the rifle perfectly to your body armor and optics configuration.

Our trigger assemblies are tuned to provide a crisp, clean break with a positive reset. This helps you maintain stability during rapid follow-up shots and improves overall target groups at long distance ranges.

We offer shipping to authorized Federal Firearms License dealers across the country. Our secure transport boxes ensure your rifle arrives in perfect condition without any scratches or impact damage during shipping.
