Optimize Your Shotgun’s Balance with a Customizable Stock Counterweight

The 390 Stock Counterweight allows shooters to fine-tune their shotgun’s balance for improved stability and control. Whether you need to restore the factory center point of balance or customize weight distribution to match your shooting style, this counterweight system is the ideal solution. Available in 5oz, 7oz, 10oz, and 12oz, these polished and blued steel counterweights are easy to install and designed to fit Beretta 390, 391, and A400 models.

Key Features

  • 7oz Stock Counterweight: Restores factory balance when paired with the #390 or #391 counterweights.
  • 5oz Stock Counterweight: Ideal for shooters who want to add moderate weight to their stock for enhanced stability.
  • 10oz & 12oz Options: Additional weight variations for full customization of gun balance.

    390 and A400 stock weights

    Posted by Darrell W Elliott on Jul 2nd 2026

    Due to the A400 Excel barrel weight, I needed to transfer weight toward the rear to counter balance the front end. I ended up ordering a 7 ounce counter weight. It is extremely easy to install, just remove recoil pad and use a 13mm socket to remove the stock nut. Then use the threaded end of the weight and basically screw it on the stock bolt just like the one you took off. You will need a flat blade screwdriver to install. Wish they utilized a dual head which you could reinstall the weight using the same 13 mm socket or a screwdriver. The gun now balances a lot more between my hands which allow a smoother swing.

    7 OZ STOCK WEIGHT FOR BERETTA 391

    Posted by GREGORY on Apr 30th 2026

    I wanted to wait until I shot 2-3 rounds of both skeet & sporting clays before I did this review. The weight of the product is exact. I measured it on a scale at the post office which reads in both ounces/tenths of ounces. My 391 was front heavy & I wanted to balance it so I didn't have to keep upward pressure on the forearm. Mission accomplished 100%. Ordering was easy, shipping was fast and the handwritten thank you on the invoice was a great gesture.

    7 OZ STOCK WEIGHT

    Posted by GREG COST on Feb 9th 2026

    I bought this for my Beretta AL-391 Sporting as the gun was a little to light for me. I added a Briley 8 OZ fore end cap to the setup & it is perfect. Installation was quick & easy & the shipping was fast.

    Great addition to my A400 multi target.

    Posted by Mike Aho on Dec 8th 2025

    Fit inside the stock perfectly. Added some much needed weight along with 16 ounces on the front to make the shotgun less whippy.
