TRUGLOairsoft-Gun-Sights

Fits perfectly on my 870 and lines up perfectly with end of vent rib. Looks great and feels strudy. Not quite as brite as I had hoped but definitely much better contrast on targer compared to the factory brass bead. Buying a 2nd for my other 870.

Fits Stoeger M3500 26" barrel well. **Update 9-Feb-2016** After two seasons of duck hunting in the swamp, and probably 300+ target rounds, the bead is holding up like a champ. My hunting buddies all like the look of the bead too. Some say it's puny in size, but I think it's great. Some reviews complain that the bead doesn't sit straight or it falls off. Please note that the mounting screws are threaded on both ends. If you can't get it to sit straight, it isn't the bead's fault. Blue threadlocker ensures that the bead won't fall off. Original review↓ After trying several different beads, I settled on this one. This one is the universal mount so it should fit about anything. I used a dab of blue thread-locker on both the bead base AND the gun itself. I would recommend this for anyone purchasing this product. I've lost beads before and there is nothing more annoying than lining up a shot and finding that your bead has gone AWOL. Pros:Large diameter bead speeds target acquisition, screws in flush with vent rib so you don't have the annoying "shelf" optical effect that most aftermarket beads have where the bead base is 0.5 mm higher than the surrounding rib. This was incredibly annoying to me on other products, and it really sold me on this bead. Universal mounting screws are threaded on both ends. This allows you thread a screw into the sight from the bottom, and then attach that screw to the gun. If the bead is slightly out of alignment to one side, simply back out the screw slightly from the bead base so more threads are available to be screwed into the gun. Cons:In my opinion, this dual color design is not as efficient as gathering light as a normal single color green bead, so it is not as bright. However, the dual color makes the sight visible against a variety of different backgrounds. This is incredibly helpful as you swing your barrel across tree cover and into clear sky like in a duck hunting situation.

Not sure why other reviews are so low... Installed on a FedArm SS12, break action, single shot12ga, smooth barrel. 1) Yes it is a bit "fiddly" to install and the screws are itty bitty. Some patience and just a small bit of skill are needed. I found the correct post, screwed the top end into the sight and screwed the post into the tapped hole on my barrel. It didn't line up. It was almost 90 degrees off. No worries, loosen the post in the barrel and retighten. This advanced the sight more forward and after a few repetitions it was on tight and aligned straight. Read several reviews that said the fiber optic cracked on install. Obviously, finesse wins out over brute strength. Part of the post protruded into the barrel. Got out the Dremel and used a small, rough grit sanding drum. At 15,000 rpm it took just a quick touch to sand the post flush with the inside of the barrel. On hindsight the Dremel was probably overkill and a manual sanding would probably do you fine. 2) Height. Yep, this things sticks up a bit taller than a standard bead. Or at least on my application it did. Note in the closeup pic that there is a small gap between the sight and the barrel. Honestly this looks made for ribbed barrels so it would likely snug down way better there. Also, I didn't use any thread locker on it. Seems I got it tight enough the way I installed it. Fired several rounds and it didn't budge. YMMV 3) Asthetics. It ain't classic, but that's not what you look for in a product if this nature. I do like the look a lot though. Better than a snap on sleeve for a plain barrel or a magnetic mount for ribbed, either of which have a huge "look at me" aspect. This is discreet, yet functional. 4) Sight picture. It was all I could ask for. The SS12 has a rather deep sighting groove on the receiver and the TruGlo Fat Bead lined up nice with it. The Dual Color is a very nice touch and I can see myself liking this more and more as I go along. Overall I'm very satisfied. I took one star off because it is a slight pain to install and the mount isn't flush on my smooth barrel. It's not quite truly "universal." However, I think it's a quality product that does what it should and at a very attractive price.

Screwed right into my shotgun.

Sight fell of to only God knows where

I have always used TruGlo products. Works like it should.

It works. Only issue I had, was the screw was a tad bit too long. Nothing a rotary tool could fix. Uses on a maverick 88

This sight was really impressive for the money. At ~20$ you could have a high-contrast bead. The circular contrast of fibers with the light channeling is what makes it pop. I shoot clays and have a few different brands and this bead would look nice on any of them. As other reviewers have stated, don't expect this thing to be gigantic. It seems compact because of the nested fiber colors, where a solid bead would take up the whole space. The odd thing to me was that the bottom is not completely flat. It has a small raised area near the screw post, maybe to keep it from rubbing off a finish? This will not hold on its own and does need some sort of adherent (loctite, etc.) As you can find on handgun forums, this is a great front sight post replacement for handguns too. I put it on a micro-compact 9 and it is not too big. the multiple thread sizes were great and I just opened the original hole slightly for threading and had a 20$ high-contrast fiber post.
