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

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.

I fixed this to the vent rib of my Remington 870 express magnum. glad I didn’t pay attention to those reviews who said it flew off or it fell apart waaa waaa….etc. I shot 12ga #4 shot all day without an issue, no gluing or other craziness.It has a recess in the sight that your original bead sight sets into and the three magnets hold it securely. It’s super bright has the sunsets . Well worth the $13

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

Works great on my Versamax tactical. I broke the original front sight and needed a replacement. I really like the large, bright light tube.The magnets were a bit stronger than I expected. I use the gun mostly for 3-gun, which means I don't walk through brush and I shoot mostly lower-recoil stuff. This survived one local match without falling off, so I think the magnets are strong enough for that purpose. I might add a very small dab of JB-weld or something like that, just to ensure it stays in place during rough handling or shooting heavy loads.

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.
