BridgeMount Rail Tactical Picatinny Rail, 7" Long with 17 Slots, BM17S, Black

This fit perfectly on my Stevens 320 shotgun. It fit the factory mount holes I have the tactical one not sure if it fit the non tactical type. I got a regular Stevens 320 shotgun without a rail years ago and bout an 11 slot rail and used E6000 to glue it on for my friend it worked and the flashlight/laser covered the mount holes anyways. But this rail fit perfectly because it has multiple mounting options to it. I did use the screws that came with this item. It did come With screws and nuts. The factory screws on mine had too small of a head but the ones it came With fit fine. I would recommend this.

I wrote another review on the 10 inch version of this which I also have on a HOWA 1500 acrylic chassis that was useless due to the flex in the forend. These awesome pic rails fixed that problem perfectly. Now it is actually a pretty great chassis that is super lightweight.

I didn't want to spend $$$ for the HK top rail for the USC, so I bought this one instead. It is a quality piece, finished nicely. I had to use my own screws, but knew that I would have to for my application anyway. Please note that on your USC, it won't rest flat on the top because the part you screw into is raised. But, it is very solid with some blue threadlock. And - BONUS - if you use a red dot designed to co-witness with AR sights, you can actually see the USC sights underneath the red dot. Obviously, you will have to zero the red dot, but maybe you can zero it for a different distance. I would highly recommend it.

Works as advertised. Not easy to install.

Great quality and great size for what I wanted

Great rails, although not enough screws sent.

Light, open down center for sighting if needed, open slots for venting in center, good finish, strong, easy to install, low profile, durable product. No complaints.

No Stops machined into the rail air Soft trash
