Step-by-Step Instructions for Assembling the Beretta PX4 Storm Full Light-Mounted Compensator (SureFire X300U-A or X300T-A Weapon Light) (video instructions linked here):

Before you begin, ensure you have the following:

• VP Armory Beretta PX4 Storm Full Light-Mounted Compensator (SureFire X300U-A or X300T-A Weapon Light)
• SureFire X300U-A or X300T-A Weapon Light
• 3/32” Allen Wrench
• Torque wrench (optional but recommended)
• Beretta PX4 Storm Full

1. Verify the Correct Light:

• Ensure you have the required light for the assembly, specifically the SureFire X300U-A Weapon Light or X300T-A Weapon Light. 
• THE COMPENSATOR WILL ONLY WORK WITH AN X300U/T-A MODEL WML- the "-B" or X300V (thumbscrew models) will NOT work with this compensator
• The -A model X300 MUST be used with the Surefire Rail-Lock Kit (included with every Surefire X300-A), installation instructions can be found here: Redirecting to Big Tex Ordinance

2. Prepare the Firearm:

• Ensure the firearm is unloaded before proceeding.
• Ensure your rail is clean.

3. Install the Lock Bar:

• The lock bar comes with a stainless wedge block that allows you to increase tension. Plastic frame guns can vary, so this wedge helps fill in any gaps and provide tension. Begin by installing the lock bar into the light, making sure to utilize the U rail lock during assembly.
• *The "U" latch on the Surefire X3000U-A or X300T-A must be used.

 4. Attach the Light:

• Proceed to attach the light onto the compensator. Start by inserting one screw to facilitate the process, then continue with the remaining screws.

 5. Secure the Screws:

• Once all screws are in place, tighten all six bolts 5 inch-pounds to ensure the compensator is firmly attached.
• If you don’t have a torque wrench, tighten all six bolts until they are fully seated, then an additional 1/8 of a turn to ensure they are fully seated and secure.

 6. Release the Lock Clamp:

• To release the lock clamp, pull back the two wings located on the sides of the assembly.

 7. Align and Slide Pistol:

• Align the rails of the pistol with those of the compensator, then smoothly slide the pistol onto the compensator.

 8. Lock the Bar:

• Push the lock bar inward until it securely locks into place, ensuring a tight and stable fit

 9. Adjust for Stability:

• If there is any noticeable wiggle or looseness, utilize the wedge block to add tension until the setup feels firm and secure.

10. Perform a Test:

• Finally, perform a quick test to verify that the installation is secure and functioning properly.

11. Completion

• Following these detailed steps will effectively assemble the Beretta PX4 Storm Full Light-Mounted Compensator with the SureFire X300U-A Weapon Light or X300T-A Weapon Light. 

PLEASE NOTE:

• Will not reduce slide velocity or induce reliability issues
• DO NOT USE WITHOUT THE PISTOL LIGHT ATTACHED TO THE COMPENSATOR. The Pistol Light is required to attach the compensator to the gun.  YOU MUST ensure the compensator is properly seated and installed prior to live fire. Failure to do so can result in damage to the compensator that is not repairable under the warranty.

How to Clean Residue from Your Firearm & Compensator

Residue buildup is completely normal—it’s just carbon and fouling left behind from firing. Over time, it can collect on your firearm and compensator, especially around muzzle devices. The good news? It’s easy to clean off, and it doesn’t damage or remove your Cerakote finish when handled properly.

Important note: We’ve seen cases where people try to scrub off the residue too aggressively, which actually ends up polishing the carbon rather than removing it. This can give the illusion that the Cerakote is coming off—but it’s really just shiny residue left behind.

Regular maintenance keeps your setup performing smoothly and helps prolong the life of your gear. In this guide, we’ll walk you through how to properly clean that buildup and get your firearm looking and functioning like it should.
