The Dead Air RXD Xeno BirdCage Flash Hider (Model RXD690) is a high-performance muzzle device specifically designed for 6mm caliber rifles that utilize the 9/16-24 thread pattern. Featuring a proven BirdCage flash suppression design and a durable Black Nitride finish, this flash hider delivers effective muzzle flash reduction while serving as a mounting platform for Dead Air’s Xeno suppressor system. The 9/16-24 threading makes the RXD690 an ideal choice for shooters running certain 6mm precision rifles and custom builds that require this less common but important thread specification.
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 robust Xeno mounting system, which features a tapered interface that provides exceptional alignment, strength, and ease of use. When paired with a Dead Air Xeno-compatible suppressor, the RXD690 allows for quick, secure, and repeatable suppressor attachment. This dual-purpose design gives shooters the flexibility to run their 6mm 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 and 9/16-24 threading.
9/16-24 Thread Pattern
The RXD690 is threaded 9/16-24, a thread pattern found on select 6mm rifles and precision platforms. This threading allows for direct installation on firearms that require this specific thread pitch, eliminating the need for thread adapters. The 9/16-24 thread provides a strong, secure connection suitable for the higher pressures and recoil associated with many 6mm cartridges.
BirdCage Flash Suppression Design
The BirdCage style flash hider has long been trusted for its ability to effectively reduce visible muzzle flash. The RXD690 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 precision shooting in varying light conditions.
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 coatings that can chip or wear over time, Black Nitride penetrates the metal surface, offering long-lasting protection against rust, wear, and harsh environmental conditions. This makes the RXD690 particularly well-suited for hard-use applications and outdoor environments.
6mm Caliber Compatibility
The RXD690 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 other 6mm precision rifle rounds. 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.
