If you own a Walther LG400 air rifle and would like to equip it with a regulator from the Walther LG300 air rifle, this is exactly the set you need!

By replacing the original LG400 pressure regulator with the LG300 regulator and using the included reduction adapter, you gain significantly wider adjustment options. This upgrade allows you to fine-tune your already excellent Walther LG400 to deliver up to 16 joules, opening up a completely new level of performance.
