How to Know What Red Dots Fit Which Gun?
When it comes to choosing the right red dot sight for your firearm, it can be overwhelming with the numerous options available in the market. With so many variables to consider, it’s crucial to ensure that the red dot sight you select is compatible with your gun. In this article, we’ll guide you through the process of identifying the right red dot sight for your firearm.
Understand the Key Measurements
Before we dive into the process of selecting the right red dot sight, it’s essential to understand the key measurements that you’ll need to consider:
- Height: Measured from the center of the sight to the bottom of the mounting base
- Width: Measured from the center of the sight to the center of the mounting base
- Length: Measured from the front of the sight to the back of the mounting base
These measurements are crucial in determining whether the red dot sight will fit your firearm’s rail or Picatinny rail.
Measure Your Gun’s Rail
To determine the correct red dot sight for your gun, you’ll need to measure the width and height of your firearm’s rail or Picatinny rail. Here’s how to do it:
- Measure the rail width: Use a caliper or ruler to measure the width of the rail. Most red dot sights come with a specific width range, so ensure that your rail’s width falls within that range.
- Measure the rail height: Measure the height of the rail from the center of the sight to the bottom of the mounting base. This measurement is critical in determining the correct red dot sight height.
Red Dot Sight Dimensions
Here’s a breakdown of the typical dimensions for red dot sights:
Red Dot Sight Dimension | Typical Range |
---|---|
Height | 1.25"-1.5" (31.75-38.1mm) |
Width | 0.75"-1.25" (19.05-31.75mm) |
Length | 2.5"-4" (63.5-101.6mm) |
Check the Red Dot Sight’s Mounting Options
Red dot sights often come with different mounting options, including:
- QD (Quick Detach) Mounts: Allow for easy installation and removal of the sight
- Tightening Ring Mounts: Require tightening to secure the sight
- Torx Mounts: Require a Torx screwdriver for installation and removal
Make sure that the red dot sight’s mounting option matches your firearm’s rail type.
Consider the Gun’s Caliber and Usage
The caliber and usage of your firearm also play a significant role in determining the right red dot sight:
- Caliber: Larger calibers often require more precise sighting, while smaller calibers may require a more relaxed sight picture
- Usage: Competitive shooting, hunting, or home defense may require different sight options

- Dimensions: Verify that the red dot sight’s dimensions match your firearm’s rail dimensions
- Mounting Options: Ensure that the red dot sight’s mounting option matches your firearm’s rail type
- Power Source: Consider the battery life and type of power source required by the red dot sight
