GDM® Hideout Muzzle Device

The GDM® Hideout Muzzle Device is part of the GDM® modular mounting ecosystem — engineered to provide a secure, repeatable interface between your rifle and the GDM® QD Mount.

Designed to pair exclusively with the GDM® LH or RH QD Mount (sold separately), the Hideout Muzzle Device allows shooters to quickly attach or detach a suppressor while maintaining precise alignment and consistent point of impact across repeated installations.

Flash Reduction & Signature Control

The Hideout Muzzle Device is designed to reduce visible muzzle flash, helping preserve the shooter’s night vision in low-light environments.

This makes it an ideal choice for nighttime hunting, tactical applications, and recreational shooting where flash suppression is a priority.

System Integration & Compatibility

When paired with the GDM® LH or RH QD Mount, the Hideout Muzzle Device enables fast, tool-free suppressor swaps across multiple rifles equipped with Hideout mounts.

Its compact length minimizes added barrel length while providing a stable, concentric mounting surface for suppressor attachment.

Available in both left-hand and right-hand thread orientations, it supports a wide range of host platforms and international thread standards.
