HIVIZ Snap On Sight for Plain Barrel Shotgun, green and red, one size (MPB)

Update 10/20/2013:I've had these for over a year at this point. I haven't had to adjust it at all. I shoot 1oz slugs all day long and the sights don't budge at all. Fast sighting, and it is much better than the bead sights during daylight and lowlights. The shotgun gets tossed around a lot and I sheath it a lot, but the sights haven't budged at all. I highly recommend these sights.Changed from 4 to 5 stars.Old Review:I got these in the mail and popped it onto my parkerized Mossberg 590. I cleaned and oiled the area with Breakfree CLP, wiped off the excess oil, and popped these right on.They fit tight, I get a great sight picture, and I love that I have extra light sticks just in case.I give them 4 stars for now based on reputation and fit. I'll come back and give them 5 stars if they can hold up well. Being plastic/polymer, I find myself questioning how loose these will become overtime and how much constant heat will affect it.Will it melt onto the barrel? Will it become weakened and fall off overtime? I can't answer those questions right now. Not even with a few trips to the range. I'll answer definitively after a few years of use and abuse.

If your home shotgun has a bead sight, put one of these on. It snaps right on. Easy. The sight shows up very well. It makes shooting in low light a breeze. I could not be happier. Low cost, HUGE improvements. Does it affect accuracy? Yes, you should shoot better. Cost vs benefit is lopsided in the benefit side. No requirement to do anything to the existing bead sight or barrel. The barrel stays original.

I love that it’s a simple, easy to install upgrade. It also comes with three other options of sight size and color. Wonderful and inexpensive product to personalize your firearm.

I don't know why, but I had the idea this sight was metal instead of plastic -- reading too many reviews, I guess. It really IS a good thing that it is plastic, though, because it gives it less momentum to pull it off the barrel when the gun fires. The shotgun I mounted it on has the barrel cut down to about 20 inches, so has no front sight post for this sight to butt against for security -- so I put a spot of epoxy glue beneath it and let it set for 24 hours before shooting the gun. So far, it has held up well and is very bright and easy to pick up in a hurry. I didn't have the problem some have had with the inserts breaking -- I think if you get the sight warm before messing with it and realize that there is a tab holding it in place and that you have to pull up the rear of the insert to clear the tab, that you will have no problems. I changed out three different inserts before deciding which I liked best and had no problems whatsoever.

first off amazon prime is the best. ordered it Saturday got it Monday! that's faster than a teenagers first handy.I have a rem 870 plain barrel with a bead sight. kinda hard to see the bead so i was looking for something that pops and the HiViz Plain Barrel Fiber Optic Shotgun Sight solved that issue. getting the site out of the package was the hardest part of assembly, i mean they locked this thing down. after hulking out on the plastic package that came with a red or green sight and 1 extra of each color. i went with the green easier to see in low light/no light situations. assembly was so easy i think a caveman could have done it. seriously unless you have a IQ below 80 you should be able to get this to work. I sent about 250 rounds down range (tough day at work) and this bad boy hasn't moved.overall great purchasePackaging A+++ (may cause you to punch a hole in a wall its packaged so well)cost A+ (cheap cheap cheap)effectiveness A+ (sights in, no movement, easy assembly)overall A+(if you have a plain barrel just get this. i went to dicks and got some fiber optics that screwed into the bead hole and they didn't even work wasted $19) officefurnitureblog.org

This is a nice, easy, cheap fix for a plain brass bead front sight. Put on an H&R pump (copy of an 870). I wouldn't try to slide it up the barrel - you'll scratch the hell out of it. Instead, put the entire plastic assembly in a coffee cup of really hot water (I didn't boil it), let it sit for a couple minutes to get pliable. Dry it off completely then snap it onto your barrel where you want it - right behind the bead. Quick, painless, easy.As far as function, it's a straightforward design. Once in place, you get a nice bright green (or red or yellow if you swap out the rods) dot that is infinitely easier to pick up in low light than a brass bead. I was considering other options for sights as the tiny brass bead is all but useless, but the shotty was a back up and only $180 - would I really spend $100-$150 for sights for it?! This was $14.99, with prime free shipping in 2 days on my shotgun. Win all the way around.

I purchased this for my old Remington 1100 12 GA on which the plain barrel doesn't have a vent rib. It works as described, easy snap on and fits just right. The sight is bright and big, easy to pick up outdoors. The problem is, like all other easy-to-install-and-one-size-fits-all stuff, it moves. There's no other tension to hold the sight on the smooth barrel but the plastic arc itself. During a 75-round trap shooting yesterday (all mild 2 3/4 7.5 bird shots), I fixed it for a dozen times trying to line it up with the bead. It's really disappoiting and distracting, I guess some double side tape could secure it some how but I really don't want to involve any glue.
