Dual scopes on AR-15?

I've seen several AR-15 builds with two scopes configured in tandem. I appears as though they are used in conjunction with one another based on how they're set up. Usually one looks like a telescopic scope while the other appears to be a red dot. Am I crazy or does someone else have this setup? If so, could you please explain the benefits?

Thanks,

the benefits are as follow....

1. you can shoot at longer range 300-500 yards using your scope and/or you can use the reddot/laser for closer 25/50 yards without changing anything.

same goes for optics/irons sight, if your optics fail "battery, hit, lost zero" you can use iron sight "BUIS"

I've never seen that ACOG/Red Dot setup before. Does the ACOG have a place for the Red Dot on it already? Or is that a special adapter that joins the two?

yes, it an adapter that holds on the back of the acog

Are you talking about a red dot attached to a scope or a swing away magnifier in front of a red dot/reflex sight?

Burris sells a set of rings that have a pictanny rail on top and will allow you to mount a mini reflex sight like the Trijicon Doctor or Burris FastFire on top of a scope.

Guys he's talking about an ESD (dot sight) with a swing out magnifier. It allows a 1x CCB optic with the ESD and magnifier swung out of the way, and also allows for a slight magnification (3x) when the magnifier is swung back into place, for the occasional longer shot.

Or he could be talking about a combination of a magnified optic like an ACOG or 3-9 scope and the addition of an off set red dot, usually mounted at 45 degrees.

Hey, cameronpersonal, what kind of tan upper is that?

Thanks :)

Judging by the mark on the deflector, I'd say it's a painted one ;)

OK, this makes more sense now! What I'd seen in the past appeared to be both optics used together. But now I see it's an either/or thing. The red dot is for tactical close range and the scope is for long range. Is that close to being in the ballpark or is there an option where you use both together like what lipadj46 is asking about in post #5?

Nice rifles BTW! :)

MovedWest,

What I think you're describing is a red dot / magnifier combination, as noted by Dr. THW. This puts a 1x optic out front (Aimpoint, EOTech, etc.), with a magnifer in line behind it. The magnifier is usually in the range of 3x to 4x, and sits in a flip-to-side mount or a quick-detach fixed mount. There is no reticle in the magnifer, it just magnifies what you see through the red dot.

This gives you a mix of close- and mid-range capability with your rifle. Similar to the concept of the 1-4x variable power optics out there. Just another way of going about it.

You probably saw a magnifier and an aimpoint being used together.

Now the OP may be interested in this set up, it allows the user to choose a red dot sight for close up work, but add the benefits of a magnified scope for distance shooting. The magnification part flips out of the way when not needed. It's common in Iraq (at least my cousin used one).
