Holosun HE510C GR HM3X Combo Great 3x Green Magnifier Set

Description

The Holosun HE510C GR HM3X Combo pairs the green 510C reflex sight with the HM3X three power magnifier, bought together. A 2 MOA dot inside a 65 MOA circle at 540nm, a titanium hood over the glass, solar failsafe, and 3x behind it when you need reach. Part HE510C-GR with HM3X.

A Note On The Part Number

You will find the Holosun HE510C GR HM3X Combo listed as HS510C-GR, HS510CG2 and a few other things across the trade. Holosun own designation is HE510C-GR, and the HE prefix matters: it means the solar equipped version.

The barcode on this one, 810047073536, resolves to the HE part. So the Holosun HE510C GR HM3X Combo you are looking at is the solar version, and there is no non solar green 510C to compare it against. If you have been trying to work out the difference between two part numbers, that is why you could not find one.

Green Behind Glass Is A Better Pairing Than It Looks

The Holosun HE510C GR HM3X Combo emits at 540nm, almost exactly where human daylight vision peaks, so a green reticle reads brighter to your eye than a red one producing the same actual light. That is useful on any optic and it becomes more useful behind a magnifier.

A magnifier takes in a fixed amount of light and spreads it over a larger apparent image, so everything you look at through it is a little dimmer than it was at 1x. A reticle with more perceived brightness for the same output has margin to spare for that. The Holosun HE510C GR HM3X Combo therefore keeps a crisp dot at 3x without you winding the emitter up to a setting where it blooms.

Why 2 MOA Is The Right Dot For This

Dot size is the specification people get wrong when they skip a package like the Holosun HE510C GR HM3X Combo when they buy a magnifier later and bolt it behind whatever sight they already own. A reticle subtends a fixed angle, so magnification enlarges the target and the dot equally.

A 6 MOA dot seen through three power covers as much of the target as an 18 MOA dot would at 1x, which throws away most of what the magnifier gave you. The 2 MOA dot in the Holosun HE510C GR HM3X Combo stays a fine aiming point at 3x, which is precisely why Holosun sells these two as a package rather than leaving you to find the problem out afterwards.

The Circle Still Works Up Close

Flip the Holosun HE510C GR HM3X Combo magnifier aside and you are back to a 65 MOA ring around a 2 MOA dot in a 0.91 by 1.26 inch window. The ring is the thing your eye catches instantly at contact distance, which is what makes a big reflex sight fast in a way no specification sheet explains.

You can also run the Holosun HE510C GR HM3X Combo as a bare dot or a bare circle. All three reticles come from the same emitter, so switching never moves your point of impact and there is nothing to re-zero. Sixty five MOA is a known angular size, so the ring doubles as a rough ranging reference against a target whose size you know.

Titanium Hood, MAO Finish, Solar

An open reflex sight stands its lens up in the air with nothing in front of it, and on a rifle that gets slung and set down the lens is the vulnerable part. The Holosun HE510C GR HM3X Combo puts a titanium protective hood over it to take the hit instead, on an aluminum body finished in MAO rather than ordinary anodising. Rated IP67 and tested to 5000G.

A solar panel harvests ambient light and keeps the sight running if the CR2032 dies or is removed. The cell is rated 50,000 hours at setting six, Shake Awake sleeps the optic when the rifle is still, and adjustments move 0.5 MOA per click across 50 MOA of travel each way. Half MOA clicks matter more behind a magnifier, because 3x makes visible the zeroing errors a 1x sight hides. Ten daylight settings and two night vision settings.

Weight And Rail Space, Said Plainly

The Holosun HE510C GR HM3X Combo sight alone weighs 4.94 ounces and measures 3.3 by 1.68 by 1.78 inches, and the magnifier adds its own weight and length behind it. On an AR carbine that is entirely reasonable and thousands of people run exactly this arrangement. On a lightweight build, or a rifle where rail space behind the optic is already spoken for, measure before you buy. We would rather you find that out here than after it arrives.
