Product Details
Key Features:
3x fixed magnification extends a red dot's usable range for target identification at distance
Ambidextrous flip-to-side quick-detach mount swings clear in a single motion for instant unmagnified shooting
Included lower 1/3 co-witness spacer aligns with most common red dot mounting heights out of the box
70mm eye relief and 7.6mm exit pupil keep the sight picture comfortable and forgiving on head position
Adjustable dioptre lets shooters who wear glasses dial the focus to suit their own eyesight
Nitrogen-purged aluminium housing sealed to IP67 stays fog-free and waterproof through poor weather
Flat dark earth finish matches FDE-furnished rifles and carbines for a consistent look
Red dot sights are quick and instinctive up close, but there are moments when a little extra reach earns its keep: confirming a target at distance, reading your fall of shot, or getting a clearer picture of what sits downrange. The HM3X is a 3x magnifier built to live behind an existing red dot or reflex sight and flip into the sight line only when you want it.
The mount is where it earns its place. A quick-detach, ambidextrous flip-to-side design swings the magnifier clear in one movement, so you drop back to unmagnified shooting without breaking position. A lower 1/3 co-witness spacer is supplied alongside the standard-height mount, which means it lines up with most common red dot heights straight from the box rather than sending you hunting for extra parts.
Optically it punches above its price. Seventy millimetres of eye relief and a 7.6mm exit pupil make for a forgiving, comfortable sight picture, while roughly 75% light transmission through optical glass keeps the image bright. The dioptre ring is a genuine bonus for anyone who wears corrective lenses. Holosun have sealed the aluminium housing to IP67 and purged it with nitrogen against fogging, and windage and elevation adjustments let you square it up precisely with your primary optic.
This flat dark earth version does the same job in a finish matched to FDE rifles. A sensible way to stretch the range of a red dot setup without the weight or cost of a magnified optic.
