HIVIZ M300 Narrow Magnetic Fiber Optic Front Shotgun Sight Black, One Size

Easy to put on and is a really bright bead. Shot trap well with it on and it stayed on the shotgun in the same place the entire time. Put it on a Benelli Super Black Eagle 2

Great sight. Magnets are good.

Makes acquiring your target much easier, fits my Remington Magnum Wingmaster 870 perfect, haven't shot it yet but it seems like its on pretty solid.

Although I ordered the wrong size for my Mossberg shotgun, this became a gift for a friend who could use it for their weapon. The magnets seemed to be very strong, and had it fit my shotgun, I believe it would have done a nice job to make my front bead area more visible in low light, and in faster target acquisition.

These made a big difference in my shooting! The bead size on this is big which makes it very effective. That's one of the stand ways I personalize my guns. No tools required - just stick on the rib with the magnets! The reason this isn't 5 stars to me is everyone I have had ends up breaking off one of those thin pieces at the end. They still work but you should buy 2 at a time. I've also lost as couple in the field and/or boat. Could be I'm too hard on equipment. Once you shoot these, you won't want another and it's a little hard to transition to another sight picture - because it's good. I bought a different type hi-viz to match the waterfowl addition SBE but it wasn't the same picture and took adjustment time at the range. I haven't found another that is better.

This is like my 4th fiber optic so that should give you an idea of how well I think they work. As far as fit, this snapped in place on my Camo 870 Supermag without any gap. As far a history goes on my other optics, I've not had a problem with losing a single one. And I'm not a trap shooter. I bust the brush, but I do it responsibly, which is to say, I know where my muzzle is at all times. But if you're worried about that kink of thing, you can get the little electronic zip ties (many colors) which should give you an added sense of security. (you might be able to glue it in place but not sure how well this works with camo coatings or any adverse affects come with it)As for the light pipe itself, I do have one that gets the most use, which is to say I change from Red to Green based on weather conditions, and the light pipes are a bit loose. It's a concern I have but I've not lost one yet. At some point in time I'll have to replace the entire optic, choose one color and fix it in place, or come up with a method to secure it and still allow me to switch light pipes.On the overall of it's display, I've hunted with a number of folks who had not used them before. After using one of mine, they've all purchased for their own guns. That says something in itself.

I like these a lot and they work well in some pretty low light conditions. check the size chart, mine worked perfect on an 870 rail but remember even the same model may have different barrels with different rail widths.

I recently bought this sight for my shotgun and stuck it on. I went out duck hunt this past weekend and on the first volley it fell off the rib and stuck to the side of the gun. Thinking I maybe bumped the sight or something I put it back on the rib of the gun. The 2nd volley it completely fell off the gun into lake Michigan. If I could leave negative stars I could.
