507 Promax Reflex Sight Red Dot

Key Features:

• Performance Reticle System giving a 2 MOA dot alone, or that dot ringed by an 8, 20 or 32 MOA circle

• Enlarged 1.18 x 0.98 inch window for faster transitions and easier dot tracking under recoil

• Forward-leaning sunshade cutting the low-angle glare that washes a reticle out

• 650nm red emitter across 8 daylight and 4 night vision settings, with memory recall and lockout mode

• Solar Failsafe backup and Shake Awake standby, running from a single side-loading CR1632

• RMR footprint for direct fitment to RMR-cut slides, plates and adapters

• 7075-T6 aluminium housing, hard anodised, IP67 rated and vibration tested to 5000G

Holosun's 507 Comp has been the default competition dot for a couple of years now, and the ProMax is what happens when you put the same reticle behind more glass. The Performance Reticle System carries over unchanged: a 2 MOA dot on its own, or that dot sitting inside an 8, 20 or 32 MOA circle, selected to suit the stage rather than the shooter. What is new is the window, up from 1.1 x 0.87 inches to 1.18 x 0.98, and the forward-leaning sunshade above it.

Those two changes matter more than they read. A larger aperture makes the dot easier to find on the first look and easier to track between targets. The sunshade leans out over the glass to keep low sun off the emitter path, which is the usual reason a dot appears to wash out just when you need it. Neither is a spec you notice on paper. Both are things you notice on the clock.

Elsewhere it holds the line. The 650nm emitter runs across eight daylight settings and four for night vision, with memory recall and a lockout mode so nothing shifts mid-stage. Solar Failsafe supplies backup power, Shake Awake drops the sight to standby when it sits still, and the CR1632 loads from a side tray without unmounting. The housing is hard-anodised 7075-T6, IP67 rated, tested to 5000G, and the whole thing weighs 48 g.

One honest caveat. Windage and elevation travel is ±30 MOA, matching the Comp but well short of the ±50 on the 407C and 507C. On an RMR-cut slide or a properly machined plate that is ample. On a marginal mount it leaves you little room to correct.

Worth a look for practical shotgun, mini rifle and gallery rifle shooters who want the Comp's reticle and a better view of it.
