Rifle Scope w/ Red Dot on AR Mounting Advice Please....

[Medic218]

Ok, I'm trying to make my Sig 522 "tacticool" but still functional for an upcoming camp for kids with cancer that I'm going to be getting involved with through a friend of mine that I work with.
The theme for the next camp is military stuff and activities.
I'm ahead of the curve having the AR styled .22...now I just need to trick it out. Where is X-Zibit when you need him???

While looking though various post on another site I'm on I found this pic.....


Ok, I thought this is what I wanted to accomplish but with the red dot so far away from the barrel I was worried about the darn thing being able to even hit a target. So what I started to think of was just mounting it as close the barrel/rail as possible.

Right now I just have a lower end BSA 4-12X40 on there with a riser, which will be replaced with taller rings, and I'm wanting to put a red dot/reflex type sight on there somewhere too.
It seems the only things I can find are at a 45* angle. Would I have to angle the weapon then to aim with it?(Firing while wearing my gas mask in basic comes to mind)
Does a rail attachment exist that is at an even(flat or 180*) level with the existing rails on the weapon and not at some angle? If you know of one please clue me in.

I've got some Amazon.com points I can use so thats where I started my search.
Here are a few things I found that I'm considering.....

I'm not totally against this idea and I think it would "look cool" but how well do you think the red dot would function being that high up?

Here is another option but being almost as much as the previous item I might as well get the one above that way I don't have to buy this and new rings too.

I Haven't looked too much at the red dots yet but this is kind of what I'm shooting for. A Burris FastFire would be nice but its just not practical right now.

What distance are you/they going to be shooting at? If they are new to shooting just put a simple red dot on it and be done with it. Nothing is more annoying than trying to shoot an AR with a scope not fitted to your personal eye relief or trying to get a chin weld because the optic is even higher than the AR's normal 2.5 inches over bore.

Been there, done that.

They make 45 degree offset red dot sight mounts that mount off a rail. Red dot is just off the bore on the ejection side of the rifle. Just rotate 45 degrees and hose away.
Alot of 3 gunners use them for their red dots.
I believe brownells sells em

This may be as close as I'm going to get to what I'm looking for. Thanks for the Brownell's tip! Thats where I found this.
