Blackbird F556 – Enhanced Pressure Control for 5.56 Platforms
The Blackbird F556 is purpose-built for modern 5.56 rifle systems. Its patent-pending Staged Pressure Vectoringarchitecture manages pressure at the source—regulating internal gas release, directing blast forward, and minimizing gas to the shooter while maintaining low back-pressure performance.
Designed to improve system reliability and shooter comfort, the F556 delivers consistent suppression across a variety of centerfire platforms. The compact form factor reduces overall footprint without sacrificing control, making it well-suited for both duty use and extended firing schedules.
Manufactured using HAYNES® 282 and Titanium Ti-6Al-4V, the F556 offers configurations optimized for durability or lightweight performance. While tuned specifically for 5.56, it also performs exceptionally on 6mm ARC, providing balanced suppression and stable gas behavior across platforms.
