Titanium vs Aluminum Magnifier Construction
Holosun offers two different magnifier housing materials:
- HM3XT Titanium Magnifier: The titanium construction provides strength while reducing weight. This model is more compact than its aluminum counterpart, making it good for setups where space and weight matter. The titanium housing handles impacts and offers added durability in tough environments.
- HM3X Aluminum Magnifier: The standard aluminum version works well at a lower price point. This model uses aircraft-grade aluminum that balances weight and durability for most shooting needs. It has the same optical clarity as the titanium version with a slight weight difference.
Both magnifiers use quality glass, providing clear sight pictures with minimal distortion and good eye relief. For additional protection during storage and transport, consider our red dot covers to protect your optical investments.
Enhance your setup by pairing any magnifier with our precision-fit Holosun red dot covers for complete lens protection.
Quick Disconnect Mounts and Flip-to-Side Functionality
Each Holosun magnifier includes practical features for field use:The quick disconnect mount allows for fast installation and removal without tools, making it easy to switch between magnified and unmagnified shooting as needed. This QD system returns to zero when reinstalled, maintaining your sight alignment.
The flip-to-side mount allows quick transitions during active shooting. When you need magnification, the magnifier sits directly behind your red dot. When you need a wider field of view for close targets, simply flip the magnifier to the side. The mount can be set up for right or left-side deployment based on your preference.Both models include spacers that allow for absolute co-witness or lower 1/3 co-witness height alignment with your existing red dot sight, ensuring proper optical alignment.
If you need both magnification and a full optic solution, check out our Holosun rifle optics with lens covers to get everything in one package.
Money-Saving Combo Packages
Our collection features several combo packages that pair Holosun magnifiers with compatible red dot sights:
- HS510C + HM3X Combo: Combines the popular open-reflex 510C red dot with the aluminum HM3X magnifier. This pairing offers multiple reticle options through the 510C (2 MOA dot, 65 MOA ring, or both) with the ability to magnify for precision shots.
- HS403C + HM3X Combo: Pairs the compact 403C tube-style red dot with the aluminum HM3X magnifier. This combination provides a traditional tubular sight picture with magnification capabilities at a more affordable price point.

The flip-to-side function ensures you're never limited to a single magnification level.Hunters value the additional identification capability when assessing game at distance, while still maintaining the quick target acquisition of a red dot for moving targets. The clear glass and adjustments help ensure ethical shots at extended ranges.Competition shooters benefit from having both magnified and unmagnified options available quickly during stages that require engagement at varying distances.
