HB Industries is proud to offer a direct replacement 3-position gas regulator for the CZ Bren 2S and MS. Our Optimized Gas Regulator Assembly includes both a new Body and Piston, both carefully tuned to provide absolute reliability and consistent ejection in a specific caliber and barrel length. Each Gas Regulator Body features three different gas settings/pressures/positions: low, medium, and high. These three settings operate as follows:

1 | Low: Ideal for shooting suppressed, or with extremely high pressure ammunition.

2 | Med: Standard operating position, optimized for consistent ejection with commercially available ammunition.

3 | High: When you need more gas to operate the action. Possible High setting scenarios include running steel cased ammunition in 5.56 models and cycling extremely dirty actions.

Strategically placed holes in the regulator knob section allow it to be rotated by hand or with a loose 5.56, this facilitates gas setting changes when using extended handguards on 11″ and 14″ Bren 2 models. Their Gas Piston is precisely machined to fit within the Gas Regulator body; they hold the tolerance between these two components at 0.0005″ or less. Their Gas Pistons feature a high performance electroless nickel coating which not only reduces friction between the Piston and Regulator, it also helps the assembly to shed carbon deposits which in their testing has reduced maintenance by increasing the time between cleaning intervals when compared to the factory components.
