Most Helpful Positive Review Great buttstock
Easy to install, great adjustability, just a well put together unit. My stock arrived missing a washer, so I contacted black river directly and they had the situation rectified in less than an hour. Sent me the missing washer and all is good. Black River had the best customer service I have ever dealt with. Definitely a company I would do business with in the future.

Great for all but the shortest position.

by John Risch, Verified Owner from CA, United States Written on February 10, 2026
Quality is good, design works. Note the shortest position does not work as the design has a flaw where the internal spring support interferes with the A300 buffer tube, Beretta's partially to blame, if you need the shortest stop to work, you would need to cut down some of the extra bolt length at the end of the a300 buffer tube, which is doable without affecting function of the action. Otherwise its looks fantastic and adds functional recoil mitigation.
Pros:
  • Fast Adjustment
Cons:
  • None
Best Used for:
  • Custom comfort and multiple shooters
Would recommend: Yes

Feels great, tames recoil, and looks amazing!

by EZ in Texas, Verified Owner from TX, United States Written on January 12, 2026
Installed on my A300 Ultimate Patrol after I had already purchased a mesa tactical urbino stock. The adjustable length of pull on this stock is a must. The adjustable cheek rest makes sure that no matter what notch you have the stock set, you’ll be able to comfortably see your irons or red dot. The added recoil mitigation of the shock force butt pad is no gimmick. Combined with the already amazing recoil mitigation of the gun itself this stock made shooting slugs buttery smooth and pain free. I put 50 plus rifled deer slugs through her in one session and could have gone 50 more. The cherry on top is it makes one bad a** looking shotgun!
Pros:
  • Built in recoil mitigation butt pad works great in tandem with A300 and 1301s already soft shooting gas system.
Cons:
  • Could use a side mounting QD sling attachment instead of bottom.
Best Used for:
  • Making your beretta shotgun the softest shooting gem in your collection.

great ergonomics better than factory stock

by Matt G, Verified Owner from CT, United States Written on January 8, 2026
This stock feels like it should be on the A300 ultima patrol from factory. The adjustable length of pull and cheek riser puts me in perfect view of my red dot. The pistol grip fits well in hand and is comfortable. I did use a rotary tool to shave a small amount of plastic down on the stock to get a perfectly flush fit against the receiver. It took less than 2 minutes and you can’t tell I touched anything. Feels quality made. Shipping was the only down side. It shipped in a plastic bag but it’s a solid stock and there was no damage.
