The Holosun MP3X (MP3X-BDC) is a fixed 3x prism scope with a BDC reticle etched into the glass and illuminated in either red or green, listed by Holosun as a new addition for 2026.
An etched reticle is the difference between a prism scope and a red dot. The pattern is cut into the glass, so it is still there with the illumination off, the battery flat, or an astigmatic eye behind it.
The housing is 7075-T6 aluminium, 3 x 2.44 x 1.77 in and 8.11 oz, rated IP67 and specified from -30 to 60 C. Illumination runs to 6 brightness settings in either colour from a CR2032 that Holosun rates at 50,000 hours. Eye relief is 67 mm with a 7 degree field of view and a 7.1 mm exit pupil, and the eyepiece adjusts 3 dioptres either way. It mounts to a Picatinny rail.
It suits close-to-mid-range shooting where BDC holdovers beat winding a turret, and it is the obvious answer for anyone who sees a red dot as a smear rather than a point. Be honest about what fixed magnification costs you: 3x is 3x whether the target is at 15 m or 200 m, and unlike a reflex sight there is a real eye box, so where the scope sits on the rail matters. Holosun does not publish an objective diameter for it.
It mounts to a MIL-STD-1913 Picatinny rail, which puts it on an AR-pattern flat-top, a straight-pull carbine or a rimfire with a rail section. Compare it with the unmagnified optics in red dot sights, the rest of the fixed-magnification range in prism scopes, and the sights chosen for straight-pull rifles.
