Red Dot Magnifier – Final Thoughts

The magnifiers listed above provide a clear sight picture, but they shouldn’t limit the clarity of your actual optic. A good magnifier should be easy to install and uninstall with ease. Why? You may need to quickly detach or attach the magnifier as situations and weather conditions change.

Likewise, the magnifiers should also remain lightweight and compact, because you don’t want to weigh down your weapon when you start to add your attachments. Additionally, the magnifier also needs to be compact and lightweight because you may have limited rail space for mounting the optic and the magnifier.

Finally a magnifier with 3x should not affect your optic’s zero — one also needs to remain the same with or without the magnifier. The best 3x magnifiers are an excellent addition to any weapon running a red dot optic and a 3x magnifier will provide a consistent and versatile amount of magnification for most ranges.

For tactical and law enforcement, the same ideas apply — a carbine with a red dot gives you the ability to quickly engage a target. And for ideal short range use, simply flip your magnifier over and you can take a more accurate or long-range shot. So, in conclusion you always want to carefully consider all of your magnifier options, read online reviews and make sure you choose one that suits your needs.
