This product does not meet the Picatinny spec. The rails are too narrow and attached items fall off at the slightest touch. Rail specs are .835 +- .005 for width and my rails are .805. The rest of the product seems just fine, attaches to a 1&#34; tube very well, but if your light falls off if you bump the gun, WTF? Too bad, it was just what I needed for a flashlight on my 500.
I'm sure it's a good attachment for some applications, but it's too big for a Remington 870 Express 12 gauge barrel.
Works just as advertized. works just fine on barrel or buffer loading extension tube. good qualiity and holds tight on barrel with 500 rounds and haven't had to retighten.
Used this to add a rail to my Stevens 320 for a tactical flashlight. I did have to pull off the barrel to mount on the mag tube (not enough space), but it fits great right behind the cap and barrel slid back over easily.
Fits perfectly with the Polymer Heatshields. Ring mount is thin enough that you can install this WITH the heatshield and have the ability to remove the barrel to clean it. Plus you get two rail lengths, which is a nice option.Very functional, affordable piece!
Worked great on my Mossberg 500 18&#34; short barrel. I found by looking for a rail mount I had a limiation of less than inch to mount one on the magazine tube. I have a 5 shot tube in mine. This one fits perfectly.
I'm putting this on my Mossberg 500 7+1 to mount my flashlight under the barrel. I was originally going to mount the light to the ATI forend grip but wanted something alittle more stream line. this should do the trick. If its made close to the quality of the NC Star weaver mount I purchased to hold my surefire light, I'm sure it will be fine.
it work exactly for my light. i had a very small space and it doesn't interfear with the rest of the rifle.
does exactly what it is supposed to the first time around. Gives excellent attachment point for a variety of accesories
