HB Industries® H&K 3-Lug Adapter

The HB Industries H&K 3-Lug Adapter converts a threaded barrel into a standard H&K 3-Lug mounting interface for compatible suppressors and other muzzle accessories. The proven three-lug system allows accessories to be installed and removed quickly without repeatedly threading them onto the barrel. It is commonly used on 9mm PCCs, submachine guns, and other firearms that utilize the H&K 3-Lug standard.

Standard H&K 3-Lug Interface

The adapter provides the industry-standard H&K 3-Lug mounting interface for suppressors and other compatible muzzle devices. When paired with a matching 3-Lug mount, accessories can be attached or removed in seconds while the adapter remains permanently installed on the barrel.

Designed for Threaded 9mm Barrels

The adapter is intended for 9mm firearms with compatible barrel threads. HB Industries offers multiple thread configurations, so the correct version should be selected to match the firearm. For example, newer factory barrels for the CZ Scorpion EVO 3 use 1/2×28 threads.

Compatible with the H&K 3-Lug System

The H&K 3-Lug system is a widely adopted quick-attach standard for 9mm suppressors and related accessories. Although many products use this interface, compatibility should always be verified with the suppressor or accessory manufacturer before installation.
