DEADAIR RXD689 RXD XENO P-SER BRDCAGE FLSH 578-24

The Dead Air RXD689 is a 578-24 threaded flash hider built on the classic Ruger Mini-14 bird cage profile, paired with Dead Air's Xeno mounting system. If you're running a Xeno-equipped suppressor and want genuine flash reduction without reinventing the wheel, this muzzle device bridges form and function: it delivers the flash suppression Ruger's proven design is known for while locking securely into any Xeno-compatible silencer. The combination makes it a straightforward choice for hunters and shooters who value a solid, repeatable platform.

The Xeno taper mounting system is Dead Air's answer to repeatability—it ensures a consistent, secure connection between the muzzle device and your suppressor, which matters when you're counting on accuracy downrange. The bird cage profile itself does the flash-reduction work: the traditional design remains effective at cutting visible muzzle flash, helping you maintain target focus in low-light conditions or when shooting beside others. Available in this compact configuration, it suits rifles and smaller-format builds where bore size and thread pitch align.

Compatibility is straightforward but requires due diligence on your part. This device will mount to any Xeno adapter-equipped silencer from Dead Air's lineup, but—and this is non-negotiable—you must verify that your rifle's bore diameter does not exceed the bore size of both this muzzle device and your chosen suppressor. A quick check of your firearm's specs and the suppressor's bore specification will confirm the fit before you thread anything on.

Frequently Asked Questions

Which suppressors does the RXD689 work with?

The RXD689 mounts to any Dead Air silencer equipped with a Xeno adapter. The Xeno taper system ensures a secure fit, but always confirm your suppressor is Xeno-compatible and that bore sizes align across your muzzle device, flash hider, and suppressor.

What thread pitch is the RXD689?

This unit is threaded 578-24. Verify your rifle's barrel threads match before purchasing.

Will this reduce flash?

The bird cage design is based on Ruger's proven flash suppression profile and is effective at reducing visible muzzle flash, which can help you stay focused on target—especially useful in low-light hunting or shooting scenarios where flash signature matters.

What do I need to check before buying?

Confirm three things: your rifle's barrel thread pitch is 578-24, your firearm's bore diameter does not exceed the bore size of this muzzle device, and your suppressor is Xeno-compatible with matching bore specifications. Mismatches in any of these create a non-functional or unsafe setup.
