Introducing the VKTR precision-machined one-piece bolt carrier designed for piston-driven AR-pattern receivers. Engineered with a patented long advance cam path, it ensures precise unlocking at 22.5 degree, perfectly timing locking and unlocking sequences. This design adds 2 degree of dwell time, effectively reducing residual chamber pressures and preventing cam pin contact with the receiver wall. The carrier is finished in thin dense chrome, facilitating easy cleaning, offering long-term wear resistance and enhancing lubricity. Featuring a patented enhanced cam pin with a directional arrow for consistent lock-up, ensuring Match-grade performance from the first shot to the last.
