The Mossberg 500 is a great shotgun that you’ll see many hunters using, as well as gunowners who want to defend their home and their property. While there isn’t anything wrong with the original sights, you may need to amp it up a little to improve your accuracy as well as your visibility with aftermarket sights. This review covers the four best Mossberg 500 sights we could find, and we’ll let you know which we think is our favorite option.
The original bead front sight is very small and can be difficult to keep focus on during low light situations or if the sun is very bright. The options listed below all feature either fiber optic or tritium inserts, which make visibility significantly better and can improve your allover target acquisition, especially when combined with a great stock. Whether you require only a front sight replacement, or both a front and rear sight, we’ve listed options that should fit everyone’s needs.

Truglo Home Defense Fiber Optic 12-20Ga Sight

Truglo Home Defense Fiber Optic 12-20Ga Sight

Materials – The Truglo Home Defense Fiber Optic 12-20Ga Sight is constructed of tough materials, built to withstand heat and firing power from your Mossberg 500. This ultra low profile sight snaps on simply to plain barrels, and is ergonomically shaped so it stays put during use. On top of the sight is a bright, neon fiber optic, which runs the length of the entire piece. It’s secured in place at two points, so it doesn’t slide around while shooting. The diameter of the fiber optic is only .078 inches, so the optic can only be seen by you and isn’t distracting or oversized for accurate target acquisition. The Truglo Home Defense Fiber Optic 12-20Ga Sight can be purchased with either a neon green or neon orange fiber optic insert.

Performance – The Truglo Home Defense Fiber Optic 12-20Ga Sight is a highly affordable front sight that is one of the easiest sights we’ve ever had to install. It simply clasps in place, and you’re ready to go! This is a cheap alternative to sights with tritium inserts, but the fiber optics work very well for those who only feel a need for sights during day light. This is an optimal choice for self defense, but, again, this will only work well during the day. We suggest sticking with the bright green color insert, as this is the more visible color, but that choice is really up to you. Don’t expect the attachment piece to last forever, but it should give you some good use if you’re not too rough with it.

What we say – The Truglo Home Defense Fiber Optic 12-20Ga Sight costs just a little under $20, so this is the best Mossberg 500 sight for anyone who is nervous to splurge on tritium inserts or is only considering replacing their front sight bead.

Pros
  • Very cheap
  • Bright green or orange fiber optic
  • Super easy installation
Cons
  • Only visible in daylight
  • Not built to last forever

The tritium is guaranteed to work for up to fifteen years of use, and the manufacturer provides a five year limited warranty with every purchase.

Performance – The Meprolight Mossberg Tru-Dot Night Sight is a step up from the previous option, in that it has the tritium insert. The great part is that a small bead sight with tritium is much less expensive than the tritium night sights we frequently review for Glocks and other handguns, so this is still a very affordable option for buyers. Although some filing is required, I little bit of precision and patience is all that’s required for an easy, at home installation. Anybody can do this. Another review mentioned that even his grandma could install this bead sight! Of course, the warranty and fifteen years of use is very appealing, so just hold onto that receipt for any replacements. With it being tritium, it would be more efficient to have a rear sight included as well, but that’s not entirely necessary.

What we say – The Meprolight Mossberg Tru-Dot Night Sight costs about $30 online, which is a very happy price for a tritium insert. This is the best choice for anyone who still needs a low cost option but would prefer to also be able to use their sight during low light.

Pros
  • Low cost
  • Tritium insert can be seen during day and night
  • Easy installation
  • 5 year warranty
