Love this sight
Review by Christain K.
Verified Buyer
I was a bit unsure when I ordered this sight, but after watching videos on youtube on how to install it, I could do a good job mounting it. I removed the factory bead and replaced it with the provided one in the XS Sight package. The only drawback is that it didn't come with the adhesive needed to bond it to the barrel. The sight itself is glued on and not screwed in. I bought J-B Weld 5,000 PSI to cement the sight. After properly affixing it, I used a small clamp to keep it in place while it dried up. After 12 hrs, it was perfectly attached. The product is well-built and sits perfectly well on my shotgun. It looks and feels like it came factory installed. The sight provides a clear and bright view in all lighting conditions. This shotgun sight, is one of the best options out there.
Works on an Ithica Featherlight Model 37 plane barrel

I had to replace the bead to fit the sight but it installed easily.

FYI: The Ithica Featherlight Model 37 plane barrel that I have took a #26s Stainless Steel Shotgun Front Bead Sight 6-48 .130"

The wrong part was sent (not the item in the KeepShooting listing) but the XS Sights crew took care of it immediately. Very impressed.

I made multiple headshots with mini slugs at 25 yards. Looks cool too.
Review by Yahira U.
Verified Buyer
I have a Mossberg Mverick 88. Installation was super easy. I unscrewed the existing sight and applied blue loctite on the new gold bead sight and screwed into the top of the barrel. Next I applied JB Weld on the Big Dot and set onto the new bead. Let set for 5 minutes and it'll never move. If you have a defensive/ home defense shotgun, you need this front sight.
Does not glow long enough
Review by Ericka F.
Verified Buyer
There is no glow of this sight long enough to be a usefull sight. I have tried ambient light and direct exposure to a 500 lumen flash light for at least 5 hours, still IF it glows it does so only for 5 minutes and then is pitch dark again.
Excellent sight for a shockwave or similar!!!

Great for a shockwave or similar, exactly what I was looking for. Easy install
Easy install, looks and works great!
Review by Murel O.

Very simple install, Used JB weld as recommended.

Will definitely be buying more for my other shotguns.
Better be good with a Dremel tool to make this fit.
Review by Paullette N.
Verified Buyer
Before installing check bead to sight and bead to gun fit. Threads on bead supplied have 0 engagement to gun. Apparently my gun has non factory threads. Bead pocket on sight too shallow.
Great idea, excellent sight and quality. BUT you need to know how to use a Dremel tool, have the right grinding tools and know how JB weld works. Understand surface preparation and be ready and able to think through the problems with out creating more.
Definitely not a drop in part(at least for me)
Pricey but worth it.
Review by Kristian O.
Verified Buyer
Lovely little (big!) bead sight. Absolutely pops in light, tritium and long lasting glow in shadow.
Easy-peasy install. Took me about 15 minutes all told.
I'm waiting for the epoxy to cure, can't wait to get this out on the range!

OK, it's on the gun now, and OH BOY. There is a nice overlap between tritium in shadow and orange in light; you can see the sight perfectly under all light conditions. I am VERY pleased! Charging with UV light yields about 20 minutes good visibility on outer ring of sight. Tritium inner dot glows nicely in shadow or dark. I wonder if the range will let me do a night shoot...
