## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    It works
  

*by D***H on Reviewed in the United States 🇺🇸 on February 23, 2021*

The picatinny is cool but there should be an option not to include it.

### ⭐⭐⭐⭐ 







  
  
    Problems with fit, but awesome customer service
  

*by M***0 on Reviewed in the United States 🇺🇸 on June 18, 2016*

The Grovtec 870 kit that I received did not fit my 870 Express with factory +2 extension. After a couple of pleasant emails to customer service, Grovtec sent out the bracket for a Remington 1100/Mossberg 500, which fit my application perfectly.The finish doesn't match the Express finish and the rail is a bit too bulky, but I'm very pleased overall with Grovtec, especially their fantastic customer service.

### ⭐⭐⭐⭐ 







  
  
    As described

Great product and exactly as described just a little pricy for what it is
