TruGlo 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.

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.

Does not fit to Remington 870 Tactical Synthetic square bead. I suppose it can be placed slightly behind the square bead but alignment with the sight would be trial and error, by eyeballing it. The TruGlo clips on to the barrel very tightly so repositioning once clamped on the barrel is very difficult, if not impossible. Removal is fairly easy. I used a plastic car door trim tool to lift the rear tapered end very carefully to prevent scratching the barrel finish. Four stars only because I cannot align it to the bead using the v-shaped groove. Otherwise it appears to be well made and clamps very tightly.

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.🫡

Easy to install and a nice upgrade to the factory bead on my Mossberg 590.

works well must have

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.

kind of impartial with this product installation was easy and i do like the sight but the fiber optic doesn’t glow in low light or at all in no light compared to their hand gun sights is there something i can do to fix that ?

Tried it on Mossberg 500 12ga 18.5" barrel with 10 slugs It doesn't fall and what most important this sight sits a bit higher that barrel brass bead sight and finally slugs went right on target. Without this sight shotgun was shooting high because barrel brass bead was lower than receiver and it was hard to take a correct aim. So I found Truglo sight sturdy enough, easy to install so I definitely pleased with it. And it will be easy to remove if by any chance I decide to do so.

Beauty edition to my M590a1. Would buy another in the future.

Pros: slips over bead sight high visibility low snag much better than bead sight Cons: its plastic

This is a perfect fit on 12 gau single the second sight i have bought Highly visible even in low light. snaps on tight

still not tested but seems good and solid
