Dead Air RXD Xeno Mounting System

P-Series Design for .45 Caliber Platforms
The “P-Series” designation indicates that this flash hider has been specifically engineered for pistol caliber applications, with particular optimization for the higher pressures and larger gas volume of .45 ACP. The internal geometry and port configuration of the RXD689 are designed to handle the unique characteristics of .45 caliber ammunition, resulting in better flash suppression performance and improved compatibility when used with .45 suppressors in the RXD line.
BirdCage Flash Suppression Design
The BirdCage style flash hider has long been trusted for its ability to effectively reduce visible muzzle flash. The RXD689 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, indoor training, or defensive scenarios where .45 ACP’s increased stopping power is utilized.
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 RXD689 particularly well-suited for hard-use applications and outdoor environments.
.45 Caliber Compatibility
The RXD689 is specifically rated for .45 caliber firearms, primarily .45 ACP. It is an ideal muzzle device for .45 pistol caliber carbines (PCCs), custom .45 AR platforms, and other large-frame .45 caliber rifles. The flash hider is engineered to handle the higher pressures and gas volume associated with .45 ACP ammunition while maintaining reliable flash suppression and structural integrity.
.578-28 Threading
The Dead Air RXD Xeno P-Series BirdCage Flash Hider is threaded .578-28, the standard thread pattern for many .45 caliber firearms. This threading allows for easy installation on a wide variety of .45 pistol caliber carbines and rifles without requiring custom threading or adapters.
