The Vltor Weapon Systems GB-2C is a clamp-on gas block designed for AR-pattern rifles with .750-inch bore barrels. If you're building or upgrading a mid-length or rifle-length AR, this gas block handles the critical job of regulating gas flow from your barrel to the bolt carrier group. The clamp-on design means you don't need to drill and pin your barrel—installation is straightforward and non-permanent, making it a practical choice for builders who want to keep their options open or swap components down the road.
Vltor's reputation in the AR community comes from solid engineering and no-nonsense functionality. The GB-2C delivers that same approach: a simple, effective gas block that does the job without unnecessary complexity. Whether you're running a designated marksman rifle, a precision build, or a general-purpose upper, a properly set gas block is foundational to reliability and controllability. The .750 bore measurement is critical—it's the internal diameter of your barrel's gas port, and getting the right size ensures your gun cycles as intended.
Built in the USA, this black-finished gas block is compatible with standard AR-15 barrel profiles and setups. It's the kind of component that doesn't draw attention until something goes wrong—and a quality clamp-on gas block from Vltor helps make sure that doesn't happen.
