Holosun MP3X 3x24mm Prism Scope with QD Mount - BDC Reticle

The Holosun MP3X is a fixed 3x micro prism optic that occupies a deliberate gap in the red dot lineup — more resolution and hold-over capability than a 1x reflex sight, far more compact and faster to use than a variable magnified optic, with an etched astigmatism-friendly reticle that stays clear without a battery and illuminates in red or green for low-light use.

The Holosun MP3X-BDC is a 3x fixed magnification micro prism optic with a 24mm objective lens, housed in a 7075-T6 aluminum body. It features an etched BDC reticle with ranging functionality, dual red/green illumination, and ships with a QD mount. The etched reticle is visible without power, providing a non-illuminated aiming reference if the battery depletes.

Fixed 3x magnification occupies a practical position in the optic spectrum for AR-15 and similar platforms: it provides enough magnification to resolve targets and apply precise holds at carbine distances — 50 to 300 meters — without the weight, bulk, or eye-relief constraints of a variable power scope. The prism optical system differs from a traditional red dot or holographic sight in that the reticle is physically etched into the prism rather than projected electronically, which means it remains visible as a black reticle even with no battery power. The BDC holdover points and ranging functionality built into the reticle allow the shooter to compensate for bullet drop at extended distances without dialing elevation or estimating holdover from a plain crosshair. Dual red and green illumination provides contrast options across different backgrounds and lighting conditions — green is often easier to see against brown and tan backgrounds, while red provides better contrast against green vegetation. The astigmatism-friendly etched reticle eliminates the starburst effect that makes standard red dots problematic for shooters with astigmatism. The included QD mount allows rapid installation and removal without tools.

Magnification: 3x fixed. Objective: 24mm. Reticle: etched BDC with ranging, red/green illumination. Housing: 7075-T6 aluminum. Includes: QD mount. Astigmatism-friendly etched reticle — visible without battery power.

Fixed 3x prism fills the capability gap between 1x red dots and variable magnified optics — faster and lighter than a 1-6x, more resolution and holdover capability than a 1x. Etched BDC reticle remains visible without power and eliminates the starburst effect for astigmatism sufferers. Dual red/green illumination for contrast across varied backgrounds.

The right choice for AR-15 and carbine users who want practical magnification for mid-range work without the size and complexity of a variable power optic — a compact, astigmatism-friendly 3x prism with a functional BDC reticle and QD mount included.
