GDM® Hideout Hybrid Muzzle Brake
The GDM® Hideout Hybrid Muzzle Brake is part of the GDM® modular mounting ecosystem — engineered to provide recoil reduction and 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 Hybrid Muzzle Brake allows shooters to quickly attach or detach a suppressor while benefiting from improved recoil control and stable point-of-impact consistency across repeated installations.
Enhanced Recoil Reduction & Control
The Hideout Hybrid Muzzle Brake is designed to effectively reduce recoil and muzzle rise, enabling faster follow-up shots and improved control — especially during rapid-fire or high-volume shooting.
When paired with a GDM® suppressor, it helps maintain stable handling characteristics while enhancing overall shooting comfort.
Included timing shims allow for proper clocking and alignment during installation.
System Integration & Compatibility
When paired with the GDM® LH or RH QD Mount, the Hideout Hybrid Muzzle Brake 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.
