Leupold has 1-4x scopes with a "Firedot" (red dot) combined with one of several reticle styles. The red dot is very small, probably 1 MOA or less, but clearly visible in dim light. In normal light, even twilight, the reticle remains clear. Most of these scopes have elevation and windage on calibrated towers. I'm looking at a 1.5-4x40 version will a milling reticle.
The Leupold "Firedot" is available in a long eye relief "Scout" scope from their custom shop, with your choice of reticles. The cost is about $550, compared to $300 for the non-illuminated version. this would be a good choice for an M1A or Mini-14 if you don't want to bridge the ejection port.
If speed of acquisition is important, as in self defense or hunting, then a red dot sight with a 3x magnifier might be appropriate, such as an Aimpoint. The magnifier is removeable, and has no effect on the point of impact. A 2 or 4 MOA red dot is a lot better for acquisition than a smaller dot, and the Aimpoint can be left on for 3 years or more, and co-witness backup iron sights on an AR. This option is NOT cheap, even if you already have the red dot sight. However, you can drive tent stakes with it, or drop it in a lake, and stay on target when you fish it out again.
