Most Helpful Positive Review A good option to add rails to a Mossberg 500 shotgun
The rails are solid but I have decided to replace this with a rail that only attaches to the magazine tube because every time you want to break down the shotgun to clean it, you have to remove this in multiple steps which gets to be tiresome after the second time you do it. Originally, I had hoped ...

Most Helpful Negative Review Does NOT work with ALL Mossberg 590s. You need to check barrel outside diameter before ordering.
The product construction is excellent. However, NcStar techs indicated that the design was based on compatibility with the latest Mossberg 590s. It did not work with my 590. If you have a barrel that has an outside diameter of about .856 then this will work for you but my Mossberg 590 had a outside ...

darn tactical

by Andrew -AR, Verified Owner from AZ, United States Written on January 3, 2021
So darn tactical it flew off the front of my shotgun into the AZ dirt, which btw is rock. I thought Id put on tight enough but I guess not. It seems huge at the end of the shotty. If I were to add an ar red dot, it looks stupendous in not an ingenious kind of way. How can I say this, it just isn't for me and i think I'll return it but maybe ill keep it as a fake grenade to be launched of the end. actually it never fell off as I now remember but it went all the towards the front sight and left some marks on my shotty. maybe some extra torque and some red locktite or maybe just blue. Anyway this thing is just barely largish and lots of rail when i just needed two, flashlight and to see if a red dot would work. The holosun hs04 was huge and didn't make it out of the house with the little .20 gauge, embarrassed. 20 gauge Remington . Its only 20$ so ima give it 20 stars-17 stars for the shotty sizing.
Pros:
  • lots of rails
Cons:
  • height weight fit
Best Used for:
  • Grenade
Would recommend: No

Doesn't fit as described

by Thomas, from IN, United States Written on November 11, 2020
Ordered it for 870 with remington factory extended mag. It will not work. It cannot be tightened down enough to fit the U shaped portion over the clamp. Even if it did fit the other reviews are correct. It would be a pain to have to take out (not just loosen) 4 allen screws every time you want to clean it.
Pros:
  • heavy
Cons:
  • won't work as advertised
Would recommend: No

Hit or Miss

by Lets Go Brandon, from NH, United States Written on February 10, 2018
This barrel mount is constructed very well and at first glance looks impressive. I bought one of these for my brand new Remington 870, it was specified for the 870 but it would not fit the extension tube or barrel. Thinking it was just a bad one I ordered another one and yet the same problem. I have since sent the second one back. Buyer beware....
Pros:
  • Well constructed, good price
Cons:
  • Misleading Adverting poor quality control
Best Used for:
  • paper weight
  • collecting dust on a shelf
  • no good us
  • Best use is to not buy it
Would recommend: No
