The Holosun HS515GM is a 1x micro rifle red dot sight in a titanium housing, running the red Multi-Reticle System on a quick-detach Picatinny mount at lower 1/3 co-witness height.
Titanium instead of aluminium is the whole argument for this model: the complete optic weighs 3.74 oz (106 g) and the body is stronger for it, not weaker.
The housing is titanium rated IP68 and IPX8, measuring 2.75 × 1.43 × 1.63 in (70 × 36 × 41 mm). The supplied quick-detach Picatinny mount puts the reticle at 1.63 in (41.4 mm), which is lower 1/3 co-witness on an AR-pattern rifle, and a side-tray CR2032 lets the cell be changed with the sight still zeroed on the gun.
The Multi-Reticle System gives a 2 MOA dot for precision, a 65 MOA circle for speed, or both together, from a 650 nm red emitter behind a 0.78 in (19.8 mm) window. Illumination runs to 8 daylight and 4 night-vision settings, adjustment is 0.5 MOA per click across ±50 MOA, and the cell is rated at 50,000 hours with Shake Awake and Solar Failsafe behind it. The quick-detach mount means the sight can come off for transit and go back on without losing zero.

What the HS515GM fits
It clamps to any Picatinny flat-top receiver or straight-pull upper and sits at lower 1/3 with AR-height irons. The aluminium version of the same sight is the HS515CM, and for a wide-window open reflex instead of a micro tube see the HS510C. More sit in red dot sights and straight-pull rifle optics.
