What To Look for In the Best Red Dot Sights for 45-Degree Mount
Image Quality
The quality of the image is very important for any optic. The red dot sight you pick should feature a wide lens crafted form high-quality glass with anti-reflective lens coatings.
Lens coatings filter light as it is transmitted through the lens. They block specific wavelengths which can reduce glare while keeping the rest of the light to generate a clear, sharp, and bright image. Lens coatings can even enhance color fidelity and image definition.
The best red dot sights for 45-degree mount ideally have fully multi-coated lenses, implying the lens is fully treated with multiple layers of coating. More layers make the coating more effective.
Brightness
A decent sight should have a range of brightness that function in different lighting conditions. A brighter surrounding light demands a brighter red dot. If the dot of the sight is too bright, it can obscure your target and consume a lot of battery power. A red dot that is not sufficiently bright can be hard to see.
A good sight should have multiple brightness settings, allowing you to select the perfect setting that matches your lighting situation. Depending on the existing lighting situation, many red dots even automatically set the brightness level for you.
Some models also have night vision compatibility, although you will probably not be pairing your red dot with a night vision gadget if you are using the sight on a 45-degree mount.
Battery
Most red dot sights run on CR2032 batteries. These batteries can offer thousands of hours of operation before they deplete but consume minimal space and add less weight. They are readily available and not expensive.
Features like the battery life and battery-saving mechanisms show more versatility. The longer the battery life, the better. You don’t want the battery to fail you in the middle of a session.
Also consider the battery placement when buying the best red dot sights for 45-degree mount. Convenient batteries are located on the side or the top so that you don’t have to remove the optic completely when making changes and affecting your zero.
Dot Size
The right dot size depends on personal needs and preferences. The ideal size is determined by your intended purpose as well.
Big dots are easy to see, supporting rapid target acquisition. However, they obstruct the target more, so they are not very good at precise shots. They are suited for close-range shots.
On the flip side, small dots are suited for more precise shooting and long-range shots, but they are difficult to see and, hence, are not the best for speed.
Size of the Sight
You don’t want a sight that is too large as it can be too heavy, particularly because you might have to use a spacer to get the height right so that your mount doesn’t block the red dot.
Construction Quality
Besides having an appropriate-sized red dot sight, ensure it is also made with robustness. The unit will be exposed to harsh conditions and severe recoil, so it should be built to handle anything.
It should be made from sturdy materials like aircraft-grade aluminum. Scratch-resistant lens coatings are also hugely essential.
In addition, the best red dot sights for 450-degree mount should be waterproof and fogproof to withstand the elements. This is accomplished by o-ring seals and gas purging.
What Is the Difference Between 45 And 35 Offset Red Dot Mounts?
The 35 degree offset red dot mount provides the user a quicker transition between their red dot and magnified optic compared to a traditional 45 degree offset mount which demands more movement and weapons manipulation.
Why Do You Need an Offset Red Dot Sight?
This kind of red dot sight allows fast target acquisition when engaging targets at varying distances. It is second to none when it comes to speed compared to other optics. Also, it is a sound idea to always have a backup if your primary optic breaks or fails. Therefore, an offset red dot equipped with a good-quality mount brings more benefits than harm.
How High Should My Red Dot Be?
For those without a specific need for an extra-tall mount, any mount that significantly inhibits their ability to find a good cheek weld can be dismissed. For most users, this will be anything with a height over 1.93″. Generally, the sight should be mounted at a height that allows for a natural, comfortable shooting posture.
Final Thoughts
The best red dot sights for 45-degree mounts will flip your shooting skills completely-in a good way. We hope the guide has presented all you need to make an informed buying decision. Picking any of the sights is one of the best things you can do; you will see your skills soar drastically.
