Dead Air RXD Xeno Mounting System
The RXD Xeno BirdCage Flash Hider is part of Dead Air’s RXD modular suppressor ecosystem. It utilizes the Xeno mounting system, which features a robust tapered interface that provides exceptional alignment, strength, and ease of use. When paired with a Dead Air Xeno-compatible suppressor, the RXD684 allows for quick, secure, and repeatable suppressor attachment. This dual-purpose design gives shooters the flexibility to run their rifle suppressed or unsuppressed depending on the situation.
The Dead Air RXD Xeno BirdCage Flash Hider combines classic BirdCage flash suppression with full Xeno suppressor compatibility in a durable Black Nitride finish.
BirdCage Flash Suppression Design
The BirdCage style flash hider has long been trusted for its ability to effectively reduce visible muzzle flash. The RXD684 uses a multi-port BirdCage configuration that disperses burning gases in a controlled manner, significantly reducing the bright flash that can impair vision during low-light shooting. This design helps shooters maintain better target acquisition and situational awareness, especially during night operations or indoor training.
Black Nitride Finish
This model features a premium Black Nitride finish. Black Nitride provides superior corrosion resistance, increased surface hardness, and a sleek, non-reflective appearance. Unlike traditional bluing or phosphate finishes, Black Nitride penetrates the metal surface, offering long-lasting protection against wear, rust, and harsh environmental conditions. This makes the RXD684 particularly well-suited for hard-use applications and outdoor environments.
6mm Caliber Compatibility
The RXD684 is specifically rated for 6mm caliber firearms. It is an ideal muzzle device for popular 6mm cartridges including 6.5 Creedmoor, 6mm Creedmoor, .243 Winchester, and 6.5 Grendel. The flash hider is engineered to handle the pressures and velocities associated with these high-performance cartridges while maintaining reliable flash suppression and structural integrity.
1/2-28 Threading
The Dead Air RXD Xeno BirdCage Flash Hider is threaded 1/2-28, the most common thread pattern for many 6mm and .223/5.56 rifles. This threading allows for easy installation on a wide variety of bolt-action and semi-automatic platforms without requiring custom threading or adapters.
