Shotguns come with factory installed sights, they are usually very simple but serve their purpose. Usually, you will find bead sight or rifle sights on shotguns. Some shotguns with bead sight also have mid-bead which helps to align bead more accurately when shooting slugs.

You can upgrade factory sights to make them better and easier to use. There are many variants of sights which are suitable for home defense, competitions are fun shooting.

So what sight is the best for your shotgun? It’s not the most expensive one but the one which makes aiming and shooting easier.

Here are several of the most popular aftermarket sights which you can install on your shotgun…

Light gathering, fiber optic shotgun sights for plain barrels

Clamp on sight

There is inexpensive solution for plain barrel of 12 or 20 gauge barrels. You can get light gathering sight which snaps in place behind factory front bead. It stays in place under recoil and makes aiming much easier even in cloudy weather. The dot shines brightly making it easier to find it and aim on target.

The TRUGLO Glo-Dot II Shotgun Sight is very popular, inexpensive and easy to install:

The Truglo Glo Dot II Shotgun Sight will add an easy-to-see glowing front sight dot to your existing shotgun. This dot is created from a fiber optic rod which attaches right onto the shotgun’s barrel. You do not have to be a gunsmith or use the services of a gunsmith to attach this sighting accessory to your weapon. You can just snap the rod onto the barrel and it will be securely in place. The only requirement is that you have a shotgun that is either a 20-gauge or 12-gauge. The make of the shotgun does not matter as long as you meet this requirement.

The diameter of the fiber optic rod is only 0.078 inches, so it will not cover targets on a long distance. The plastic base of the sight has a matte finish and is 2 ½ inches long. The base contains a notch which utilizes the front bead of the barrel to accurately locate the glowing dot along the axis of the bore.

You can purchase the sight to have a glowing dot that is either red or green. They are the same quality and price, but just a different color. Both will work just as effectively when trying to aim in any conditions.

These sights are made for un-ribbed shotgun barrels that are 20-gauge or 12-gauge. And although the sights consist of plastic and polymer materials, they are constructed to be durable enough to sustain harsh environmental conditions, such as weather.

If you’re looking for a better front sight while you’re out in the woods or even trying to defend your property against unwanted intruders, then a small investment for the Truglo Glo-Dot II will go a long way.

The price is only $16.99 at Brownells.
