Engineered for signature management and reliable function under sustained use. The FLOW 556K is designed for multi-caliber platforms where repeatable cycling and reduced signature are mission priorities. The package includes a 1/2×28-threaded flash hider and is built for rapid field attachment.

Ruggedized for duty use with attention to modularity and rapid deployment. Emphasis on flow-through design and torque-lock retention minimizes impact to bolt velocity and supports consistent follow-up shots when operating under stress.

Key Specifications
