Doublestar Corp. DBST Bolt Carrier Group with O Ring

In the realm of firearms, reliability and durability are paramount. Here we present a complete bolt-and-carrier group designed to meet these exacting standards for your AR-15 platform. This assembly is crafted to seamlessly integrate with any standard mil-spec AR-15 upper, ensuring that you can focus on what matters most—marksmanship.

The heart of this component lies in its batch magnetic particle inspected bolt. This rigorous inspection process guarantees an extended service life by identifying potential flaws before they become issues. Such attention to detail ensures that each piece stands up under pressure, providing peace of mind during operation.

Both the bolt and carrier boast a matte black phosphate finish—an essential feature for those who demand their equipment resist heat, wear, and corrosion over time. A chrome-lined carrier further enhances durability while maintaining smooth function throughout use.

Additionally, the gas key is staked securely to prevent loosening during repeated firing sessions—a testament to thoughtful engineering aimed at preserving functionality across conditions.

Included within this comprehensive package are all necessary components: the bolt assembly itself, a reliable firing pin alongside its retaining pin, cam pin for proper alignment and movement control, and finally—the complete carrier ready for action.

For those who seek excellence in every shot fired from their AR-15 rifle system; consider this meticulously engineered bolt-and-carrier group as part of your armory.
