AIM-O DP Pro Red Dot Point Sight

Open reflex sights have one weak point and it is the lens, sitting exposed at the front of a squared-off frame waiting for a BB. The shape of this body is the answer: the sides rise and angle in so that an incoming round meets sloped aluminium and skids off it, instead of arriving square onto the glass.

The same geometry does something for stress. Mount a rigid optic on a gun that cycles and the frame transmits every jolt straight into the lens seat. A housing that flexes along its angles deflects that load away from the glass, which is the difference between an optic that survives a season of a gas rifle and one that does not.

Illumination is the quiet strength here. AIM-O describe it as working in any light condition, and that is the practical test — a dot you can see against a bright sky and still see inside a dark building without fiddling with a switch between rooms.

It is aluminium, it takes one CR2032, and a lens cover comes in the box. Adjustment is the usual windage and elevation pair on a standard 20 mm mount.

Specifications

Good to know before you buy

This is an open reflex, so the emitter and the lens are exposed. The shaped housing helps, but if you want a sight that is sealed against a direct hit, an enclosed pattern is the one to buy.

Red only. If you specifically want a green dot for brown winter ground, look at the red and green patterns in the range instead.

Fit the lens cover when the gun goes in the bag. The front glass is the part that gets scuffed, and a scuffed lens is a fuzzy dot forever.

Frequently asked questions

What does the odd housing shape actually do?
Two things. It presents angled metal to an incoming BB so the hit glances off rather than landing flat on the lens, and it routes mechanical stress around the lens seat rather than through it.

Is it any good indoors?
Yes. AIM-O rate the illumination for any light condition, which in practice means the dot stays visible from a bright field to a dark room.

Can I put it on a pistol?
It mounts to a 20 mm rail rather than a pistol optic footprint, so it needs a slide-mounted rail plate. Our ACRO and RMR pattern sights are the direct pistol options.

Does it come with a battery?
No. It takes a single CR2032 and you will need to supply it.

Which colour should I pick?
Function is identical. Black on a black gun, dark earth on anything tan — the dark earth is a couple of pounds dearer because our supplier prices it that way.
