AR15 Optics: The Red Dot Sight Guide


A Red Dot Sight upgrade and some range time can lift your AR game to new heights. Which sight should you choose? TheNewRifleman wants to help you make the best choice for your needs and for your wallet.

A Primer on AR15 Optics: The Red Dot Sight Guide

With your first AR15 purchased, it won’t be long before you start looking at upgrades. The best red dot sight for your needs might be a poor choice for someone else. There are a variety of styles that you can choose from and I have put together a guide to point you in the right direction. I have a strong urge to tell you before you choose any upgrade to 1) save up for decent upgrades over junk, and 2) to make your first upgrade a reliable optic, be it a red dot or otherwise.

Red Dot Sights

The red dot sight has become a common choice for a first upgrade and often the low-cost of entry makes it very attractive. A red dot sight has a red (or green) circle of various sizes and the dot (or chevron) is placed on the target and the weapon is fired. With the red dot sight, we have multiple technologies in place ranging from fiber optics to holographic reticles. The first step is to choose a dot size and shape that will best fit your uses.

Dot Size, Dot Pattern

Choosing the wrong reticle for your use can be a hindrance. Making the proper choice of dot size and shape is dependent on your uses. Too small a dot and it won’t be as quick to pick up by the eye. Too large a dot and the dot can obscure your target if you are shooting at longer distances. Some red dot sights attempt to fix this issue by allowing a large circle dot reticle where there is a large ring with a precision dot in the center.The Eotech reticle is a perfect example. Deciding what dot to choose is the first step, and it is important to pick something that will suit your uses.
