Description
Triple your effective range instantly without sacrificing close-quarters speed with titanium-tough construction that’s nearly an inch shorter than competing magnifiers.
Extend your red dot sight’s capability from point-blank to 300+ yards without adding a second optic or compromising your rifle’s balance. The HM3XT bridges the gap between your unmagnified red dot and dedicated rifle scope, letting you identify targets at distance while maintaining the speed advantage of reflex sights up close. Built from aerospace-grade titanium with multi-coated optics and a nitrogen-filled housing, this magnifier delivers crystal-clear magnification that survives the harshest conditions while taking up minimal rail space.
Key Features
- Grade 5 Titanium Construction: Built from aerospace-grade titanium throughout the entire housing and mount, providing more than double the tensile strength and five times the fatigue strength of 7075 aluminum while maintaining a compact 11.6 oz profile
- Ultra-Compact Optical Design: Measures just 3.2 inches in total body length—nearly one full inch shorter than the aluminum HM3X model—allowing better clearance for charging handles and backup iron sights without sacrificing optical performance
- Ambidextrous Quick-Detach Mount: Features a tool-free flip-to-side mechanism that can be configured for left or right-handed operation, with an included height spacer providing both absolute co-witness (1.41″ center height) and lower 1/3 co-witness (1.63″ center height) mounting options
- Premium Multi-Coated Optics: Nitrogen-filled housing with multi-layer coated lenses delivers 80% light transmittance and a 33.3-foot field of view at 100 yards, with an adjustable diopter range of +/- 3 for personalized focus regardless of eye condition
Important Compatibility Notes
- Mount features precision positioning lugs that require mil-spec Picatinny rails; some non-standard or narrow aftermarket rails may not achieve proper lock-up
- When using with backup iron sights, the diopter ring may require gentle pressure to clear the rear sight when flipping up (this is normal and does not affect function)
- Flip-to-side mechanism can be reversed for left-hand operation by removing and reinstalling the mount hardware
Why We Carry It
The HM3XT represents a significant engineering achievement in magnifier design—Holosun managed to reduce the overall length by 0.88 inches compared to their aluminum HM3X model while simultaneously upgrading to Grade 5 titanium construction. This shorter profile solves a common problem shooters face with magnifiers: rail space. The compact design allows the magnifier body to sit closer to the charging handle on AR-pattern rifles, providing better eye relief without forcing your red dot sight forward onto the handguard.
Frequently Asked Questions
Will this work with my specific red dot sight?
The HM3XT is designed to work with any red dot sight using either absolute co-witness or lower 1/3 co-witness height standards. The included spacer allows you to match your red dot’s mounting height. The key is ensuring your red dot and magnifier align at the same optical center height.
How does the titanium version compare to the aluminum HM3X?
The HM3XT is approximately 1 inch shorter in overall length (3.15″ vs 4.03″) and features Grade 5 titanium construction throughout both the magnifier body and mount. While the weight difference is minimal (10.5 oz vs 10.9 oz), the titanium offers significantly superior strength and durability. The optical performance is essentially identical between both models, with the same 3X magnification, eye relief, and field of view specifications.
Can I adjust the tension on the flip-to-side mechanism?
Yes, the flip-to-side mechanism includes tension adjustment capability. If you find the detent becoming loose or too tight over time, you can adjust the tension using a T10 L key.
