Details
Description
Titanium is the whole point of the Holosun HM3XT Magnifier. It does the same job as the aluminium HM3X — flips in behind your sight for 3x, swings aside on its QD mount for 1x — but the titanium build takes noticeable weight off the rifle, which is what you are paying for.
How It Compares
The standard aluminium version of this magnifier is the HM3X. For more reach than 3x, step up to the 6x HM6X. The full selection is under magnifiers, and choosing a red dot magnifier explains the trade-offs.
Ideal For
- Weight-conscious carbine builds
- Adding 3x reach behind a red dot you already own
- Shooters moving between 1x and 3x often
- AR-15 rifles where every ounce on the rail counts
Key Features
- 3x magnification in a titanium body
- Flip-to-side QD mount with adjustable co-witness height
- ±3 diopter adjustment to suit your eyesight

Product FAQs
What do I gain with the HM3XT over the HM3X?
Weight, and only weight, because both magnify 3x. The HM3XT titanium body is the lighter of the two.
Will the HM3XT sit right behind my optic?
Yes, the mount has adjustable co-witness height, so you can line the magnifier up with the sight you are running. It uses a flip-to-side QD mount.
Does the HM3XT work with holographic sights?
It pairs with most red dots and holographic sights. The HM3XT flips in behind your sight for 3x and swings aside for 1x.
What is the diopter adjustment on the HM3XT for?
The plus or minus 3 diopter adjustment lets you bring the magnified image into focus for your own eye. It is built into the magnifier.
What magnification does the Holosun HM3XT give?
The HM3XT is a 3x magnifier. For more reach than 3x, the 6x HM6X is the step up.
What is the HM3XT made from?
The HM3XT is a titanium build, which is the whole point of the model. Titanium takes noticeable weight off the rifle compared with the aluminium HM3X.
Do I need to remove the HM3XT to shoot at 1x?
No, it swings aside on its QD mount for 1x. That makes moving between 1x and 3x quick.
What comes with the HM3XT?
The package includes the Holosun HM3XT titanium magnifier and its flip-to-side QD mount.
Who is the HM3XT aimed at?
It suits weight-conscious carbine builds and AR-15 rifles where every ounce on the rail counts. It also suits shooters moving between 1x and 3x often.
When will my HM3XT be delivered?
Estimated UK delivery is 10 business days. It ships as genuine UK stock, so there are no import fees to pay on arrival. Checkout is secured by Shopify.
