The Holosun MP3X Prism Scope (MP3X-BDC) is a fixed 3x prism scope with a 24 mm objective and an etched BDC reticle illuminated in red or green, supplied with a quick-detach Picatinny mount. It weighs 8.82 oz (250 g) in a 7075-T6 aluminium housing.
The etched reticle is the reason a prism scope exists. Because the BDC pattern is cut into the glass rather than projected by an LED, it stays fully usable with the illumination switched off, and it holds a clean shape for shooters with astigmatism, who often see a red dot as a comet or a smear rather than a point. Add fixed 3x magnification and holdover marks and it covers ground a 1x dot cannot. Illumination runs 12 settings, 10 daylight and 2 night-vision compatible, in either colour, from a CR2032. Eye relief is 2.55 in (65 mm) with a 6.6° field of view.
How It Compares
Against a red dot, the MP3X trades unlimited eye relief for magnification and an etched reticle. If you would rather keep a 1x sight and add magnification behind it, the HM3X 3x flip-to-side magnifier pairs with a dot such as the HS510C red dot sight, or buy them together as the HS510C and HM3X combo. For a 1x enclosed sight instead, see the AEMS Macro red dot sight. Browse every prism scope we stock and our wider range of AR-pattern rifle optics.
Ideal For
- Shooters with astigmatism, who see an etched reticle far more cleanly than a red dot
- Civilian Service Rifle and practical rifle on straight-pull AR-pattern carbines
- Close-to-mid-range shooting where BDC holdovers are quicker than dialling
- Rimfire and pistol-calibre carbines needing a little magnification on a Picatinny rail

Frequently Asked Questions
Why choose a prism scope over a red dot?
The BDC reticle in the Holosun MP3X Prism Scope is etched into the glass, so it stays sharp and fully usable with the illumination switched off, and it holds its shape for shooters with astigmatism who see a projected red dot as a smear. It also gives fixed 3x magnification, which a 1x red dot cannot.
Is the Holosun MP3X good for astigmatism?
Yes. Because the reticle on the Holosun MP3X is etched rather than projected from an LED, it does not smear or flare for shooters with astigmatism the way a red dot commonly does.
What magnification does the Holosun MP3X have?
The Holosun MP3X is a fixed 3x prism scope with a 24 mm objective. The magnification is not variable, which is what keeps the optic compact and the eye box consistent.
What is the eye relief on the Holosun MP3X?
Eye relief on the Holosun MP3X is 2.55 in (65 mm), with a 6.6° field of view. Unlike a reflex sight it does have a defined eye box, so mounting position on the rail matters.
Does the Holosun MP3X come with a mount?
Yes. The Holosun MP3X is supplied with a quick-detach Picatinny mount, so it fits a standard Picatinny rail without a separate purchase.
What colour is the illumination on the Holosun MP3X?
The Holosun MP3X offers dual red and green illumination across 12 brightness settings, of which 10 are for daylight and 2 are night-vision compatible, powered by a CR2032.
