HB Industries® H&K 3-Lug Flash Hider Adapter

The HB Industries H&K 3-Lug Flash Hider Adapter combines a standard H&K 3-Lug suppressor mounting interface with an integrated flash hider for 9mm firearms. It allows compatible suppressors to be attached and removed quickly while also reducing visible muzzle flash when shooting without a suppressor. Once installed, the adapter can remain on the barrel, providing a permanent 3-Lug mounting interface for compatible suppressors.

Standard H&K 3-Lug Interface

The integrated three-lug interface follows the industry-standard H&K 3-Lug pattern commonly used on 9mm PCCs and submachine guns. When paired with a compatible 3-Lug suppressor mount, it allows rapid attachment and removal without repeatedly threading the suppressor onto the barrel.

Integrated Flash Hider

Unlike a standard 3-Lug adapter, this model also functions as a flash hider. It helps reduce visible muzzle flash when firing without a suppressor, eliminating the need to swap muzzle devices depending on the shooting configuration.

Designed for Threaded 9mm Barrels

The adapter installs directly onto a compatible threaded barrel and is intended for 9mm firearms. Once installed, it provides a secure H&K 3-Lug mounting interface for compatible suppressors. Before installation, verify both the barrel thread specification and suppressor compatibility.
