The green-emitter 510C paired with Holosun's HM3X 3x flip-to-side magnifier, supplied together in a hard case. A selectable 2 MOA dot and 65 MOA circle handle close-range speed, and the magnifier flips in when you need to identify something further out.
Key Features:
2 MOA dot, 65 MOA circle, or combined circle-dot, selectable to suit precision or speed
540nm green emitter holding contrast in bright light, with 10 daylight and 2 night vision brightness settings
HM3X 3x magnifier on an ambidextrous flip-to-side QD mount, spacer included for absolute or lower 1/3 co-witness
Solar Failsafe and Shake Awake stretching a single CR2032 to a claimed 50,000 hours on setting 6
Aluminium body with a titanium hood shielding the wide open window
0.5 MOA clicks across ±50 MOA of windage and elevation travel
Both optics IP67 rated and vibration tested to 5000G, supplied in a fitted hard case
An open reflex sight answers close range and runs out of resolution the moment you need to tell one target from another at distance. A magnifier fixes that, but only if the two are height matched and mounted to work together. This set removes the guesswork by shipping both, already matched, in one case.
The sight is the HE510C-GR, the green-emitter version of the 510C. Wide open window, titanium hood, and Holosun's multi-reticle system giving you a 2 MOA dot for precision, a 65 MOA circle for speed, or both together at the press of a button. The 540nm green LED holds contrast in bright conditions, Solar Failsafe supplements the CR2032 with ambient light, and Shake Awake drops the optic to standby until it is moved. Windage and elevation adjust in 0.5 MOA clicks across ±50 MOA.
Behind it sits the HM3X, a 3x magnifier on an ambidextrous flip-to-side quick-detach mount with 70mm of eye relief and a ±3 dioptre ring to suit your eyes. A spacer is included for absolute or lower 1/3 co-witness. Flip it in to identify a target, flip it out for an unmagnified sight picture, and neither costs you your zero. Both units are IP67 rated.
In UK terms this belongs on anything with a Picatinny rail and a reason to shoot fast and then carefully. Straight-pull carbines, Section 1 semi-automatic rimfires, gallery rifles, practical shotguns. The optics themselves need no certificate. What you mount them to almost certainly does.
A sensible package for a shooter who wants one setup covering ten yards and a hundred, with nothing to swap in between.

The HM3X, which is what this set includes. It is height matched to the 510C and ships with a spacer for absolute or lower 1/3 co-witness, so the two line up without needing an adapter or a riser bought separately.
The green model uses a 540nm emitter and holds contrast well in bright conditions. The red uses a 650nm emitter. Reticle, housing, battery and mounting are otherwise identical. It is a sight picture preference rather than a performance difference, so pick the one your eye reads faster.
No. The magnifier sits behind the sight and does not touch it. Zero lives on the 510C. The HM3X has its own windage and elevation adjustment so it can be aligned to the sight once, and the quick-detach mount returns to the same position each time.
