Low-Profile Universal Home Defense Fiber Optic Front Shotgun Sight Fits 12-20 Ga, Red/Green

Giving product 5 stars. Purchased for Mossberg 590 Shockwave 12 gauge with barrel bead. Made of strong plastic. Instructions say install from back first at 45 degree angle, then press down into place. Problem with that is it is impossible to guess if it will line up correctly with bead. Tried that way and was off 1/4 inch and was at an angle. Nearly impossible to remove from 12GA Shockwave barrel once installed. Had to use plastic putty knife to get under and pry for removal. Tried instruction way 2 times and was still off. Went the other way, started by lining up at bead side, then pressed that into place first. Was a little crooked and not into the notch where bead goes. Was able to press opposite end into straight line, then with small punch and hammer, gently tap front end down where notch surrounds bead. After that, I was able to inspect product. Must say that this fiber optic is definitely a winner. I purchased the green version and even in dim light it is very easy to see. Took it into my basement after dark where I have a small led night light. It was enough to lite the green fiber with no problem.. In daylight or bright rooms, the green optic is very intense and easy to see! I had ordered an XS Trijicon for my 12GA with the bead. Found out in order to install the Trijicon, you have to change beads and use JB Weld and actually cold weld night site to shotgun barrel. Then to remove, choices according to mfg is propane torch or something to heat the JB Weld. Not on my new $500 home defense shotgun! Going that route, if you removed, say bye bye to barrel finish! Don't need a night sight that bad. I was very pleased with this Fiber Optic snap on product. So impressed, I ordered 1 more green and the red version to compare. Will keep extra ones for backups. Sometimes good products come and go, so if something like this, I always buy a 2nd one to stash. The optic itself has a small amount of movement. Will place 1 small drop of clear gorilla glue on bead side which will stop the movement.

Rugged, easy to install. Nice green dot. Great quick reference point for aiming, better than factory brass bead. I bought another the next day for my other shotgun.🫡

I chose this rating because this sight does what it says, it snaps on easily, it gives you a really nice glowing red front sight, and stays on through firing. It's tight on the barrel and I wouldn't worry about it coming off through normal use/shooting, but the reason I only gave it 4 stars was that I feel like it could be removed/broken if the muzzle takes much of an impact. I fired several rounds after installing it and it didn't budge an inch. Good sight for someone who wants to inexpensively improve the sight picture/acquisition on their shotgun.

For improved sights on my Shockwave I tried a low cost red laser, then a low cost green laser. The red dot was too hard to see in the bright sunlight, and the green worked great but dimmed quickly (overheated?). I could have bought a better green dot laser but didn't really like the extra "appendage" on top of my shotgun that wouldn't fit in my scabbard, so decided to try this simple green fiber optic sight. It is simple, won't quit working, is low-profile, light weight, and is easy to see in bright sunlight so I'm pleased. It went on easy and fits tightly so it hasn't budged. I did spray it with some Krylon camo plastic paint I had on hand to give it a little more eye appeal (the large black plastic piece on the end of the shotgun just didn't get it for me) so I'm very happy with this sight.

Very nice easy install snaped it right on took a little force not much to line up then just took a heavy hunting knife tapped it forward into place didn't even take a minute or two dont see what people are complaining about hard to install or easy to break very nice sight bright only way it could be better if it was made of rubber coated aluminum if your thinking about buying one buy it i almost didn't because of some of the reviews another great tru glow sight great addition to any shotgun self defense or hunting

Really nice for what I needed I removed the rail or cantaliever arm and clipped this to the front it snaps on pretty tight and got a little mid sight I made for reference it'll be nice for what I need it for my grounds are more tight spaces and won't be for distance so the red dot I had wasn't doing as much good as a simple green bead attached to the end of 835 it's got the rifled barrel with 3 inch accutip Remington to really give some knock down wish me luck.

I have purchased a few of these before with no issues. But I think this time I got a defective one. I heard a slight crack type sound when Installing. I will see if it holds up while I use it.

Snapped right on and, after a little nudge, it snuggled right up against the bead. Very tight fit; I don’t expect it to fall off or move during/after firing. Not useful in low light, no surprises there, but it was a super quick index and acquisition when there’s enough to see by.
