The Holosun 507 Promax Reflex Sight Green Dot puts the green Performance Reticle System behind an enlarged window with a forward sunshade, on the RMR footprint.
The Holosun 507 Promax Reflex Sight Green Dot pairs a large window with a high-contrast green reticle on the RMR footprint. It is built for fast shooting, where finding the dot quickly counts for more than a small housing.
Green is the reason to pick this version. Holosun pitches it for bright days and busy backgrounds, which are the conditions where a dot most needs to stand out. If your eye takes to red, the red 507 ProMax shares the same window, sunshade, reticle options and footprint.
Most shooters choose a reticle and leave it there. The bare 2 MOA dot suits slower, precise shots at gallery rifle distances. The 20 and 32 MOA circles pull the eye onto the dot on close, quick stages. Once it is set, lockout mode stops a gloved hand or a range bag from changing brightness or reticle mid-stage. The four night vision settings sit below the eight daylight ones, and memory brings the sight back to your last setting when it wakes.
Adjustment is 1 MOA per click with ±30 MOA of travel. That is plenty on an RMR cut slide or a properly machined plate, so the sight pairs best with a quality mount rather than a budget adapter.
It sits at the large-window end of our reflex sights, and suits practical shotgun, gallery rifle and long-barrelled pistol shooters who want a wide, clear view of the dot.

Choose by whichever colour your eye picks up fastest. Holosun pitches the green reticle for bright conditions and busy backgrounds, where high contrast helps the dot stand out. The red 507 ProMax shares the same window, sunshade, reticle options and RMR footprint, so the emitter colour is the only real decision. Preference varies a lot between shooters, so looking through both helps.
The ProMax is Holosun's large-window take on the 507 design. Its headline changes are a noticeably bigger viewing window and a forward leaning sunshade over the glass, both aimed at an easier sight picture during fast transitions. If you already run a Comp and get on with it, the ProMax is a wider view rather than a different way of shooting.
It uses the RMR footprint, so it fits directly to RMR cut slides on long-barrelled pistols, and to RMR pattern plates and rail adapters on gallery rifles, practical shotguns and other long guns. No adapter is needed where the cut or plate is already RMR. Check the plate specification before ordering if your mount came from a third party.
Yes. The CR1632 sits in a side loading tray, so the sight stays on its mount while you swap the cell. That avoids removing and refitting the sight, which is the usual way a zero gets disturbed. Solar Failsafe and Shake Awake stretch the time between changes, but the battery remains the main power source.
