The Holosun HM3XT is the titanium version of the HM3X 3x magnifier — same fast flip-to-side performance with an upgraded, lighter and tougher titanium housing. Flip it in behind a red dot or holographic sight for magnified target ID, then swing it aside for 1x speed.
It rides on a QD flip-to-side mount with a spacer for absolute or lower 1/3 co-witness, and has an adjustable diopter for a sharp picture.
How It Compares
The aluminium HM3X offers the same optics for less; the HM3XT adds a titanium housing for reduced weight and extra durability. Want more reach? See 5x/6x options in red dot sight magnifiers. Not sure which? Read our magnifier guide. Building an AR? See AR-15 optics.

Frequently Asked Questions
HM3XT or HM3X?
Identical 3x optics; the HM3XT has a titanium housing that's lighter and more durable, the HM3X is aluminium and more affordable.
Will it work with my red dot?
Yes — it pairs with most red dot and holographic sights at a compatible mount height; the spacer supports absolute and lower 1/3 co-witness.
Does it have its own reticle?
No — it magnifies your sight's existing reticle.
