HIVIZ Spark II Fiber Optic Shotgun Sight – Universal Front Sight for Shotguns – Bright & Durable Replacement Bead

I was told my shotgun's front bead was 6x48 thread. That was wrong. Instead of going to a gunsmith, I found this HIVIZ product. It's the perfect solution for installing a new front sight on a shotgun when you do not know the correct thread size. HIVIZ provided 5 thread sizes to match your specific gun, so you don't have to guess or recut the threads on your gun. That is the reason I purchased it. Any other sight you better know the thread pitch. Some reviews say the material is soft and they damaged the threads screwing them into their gun. It's designed that way so you don't damage your guns threads. That's why you test fit the different adapters to see which threads on properly. The fiber optic is standard stuff, it needs light to work. It's not a low light/night sight. I'm highly satisfied with the sight's quality and ease of installation. I needed tweezers and my reading glasses to install.

Nice and bright like it a lot

Fit great on my h&r pardner pump. However I needed to use the mossberg 500 screws as opposed to the Remington 870. Nothing wrong on the manufacturer, the h&r is just a clone, so not everything is exactly the same. 4 stars because it’s not as large or visible as I had expected.

Installed on my home defense shotgun (Mossberg Maverick 88 12ga). The tiny green dot is handy and works as expected, but it's also way better than the brass bead sight when I'm using the mounted light at night. The black metal housing around the green dot absorbs light and contrasts clearly with the bright background. The stock brass bead is reflective and washed-out by comparison.

Easy to install easy to see

This is a good front bead replacement. It doesn’t illuminate like the 1 inch long beads, but it works fine. It comes with multiple base size threads, which have to be able to fit on any gun.. I would buy it again if I needed it.

very nice , quick shipping thanks

This sight is junk! I just received one that cost $10.99. Now I see they are down to $5.99. Even at that price I don't think they are worth it. I already own four of the HiViz magnetic sights, and two of the Comp Sights. They are good sights; however, the Spark II doesn't compare. It is not very bright compared to their other sights, and it is very easy to ruin the sight during installation. First the screw is hard to install in the rib. Then, when the sight is screwed onto the screw it probably won't line up. So you must remove the sight (the screw will probably also come out) and sand the bottom of the sight. If you happen to sand a little too much off, the sight is basically ruined, because if you try to sand off enough to make another 340 +/- degree turn, the screw hits the fiber optic.Save your money. HiViz makes a number of very good sights, but the Spark II isn't one of them.

Bit tidily to fit

It was tricky to install, but most beads are difficult due to size. Once I finally got the right screw in the assortment it went on nice and tight. I put it on an older baikal ij 18m. It took the 3mm x 6 screw I think. I used blue loctite as well. Glows nicely in the sunlight.

Sight fits perfectly on my SxS Baikal Izh54 with tapered rib. Great product. Many options to choose from in one pack.

Wast of good money waited almost 3weeks did not fit local gun Smith advised throw away utter junk hense. One stars

not as illustrated..... will need microscope to install it ...very very very small
