I did some searches, and realize there is a LOT of information already here on this. But I have some specific requirements/desires, and hoped you all wouldn't mind if I added one more topic.

I have an M&P 15-22 MOE, with Magpul folding sights, and got a BSA 4-14x44 tactical scope for it, with QD mount, which works great. I'd like to also get a red/green dot as well. Here's what I'm thinking:

* 1x bright Red/Green Dot. I'll be shooting mostly outside in bright sun, and have heard green dots show up better.

* Multiple reticle style. I've seen some with crosshairs plus the dot, circle plus dot, and I think that would be much easier for me to use.

* Over 1 MOA dot? My eyesight is not that great, so I use corrective lenses for distance, and will be using them with the sight. I have slight astigmatism. What I've read on 1 MOA dots might mean I'd have a rougher time with them. Although having a circle plus a dot would definitely help, I'm sure.

* Quick Disconnect Mount. I LOVE the AR-PEPR mount on my sight, and want to be able to swap out with the red/green dot scope without re-sighting.

* Co-witness with MBUS sights. VERY important to me. Could be lower 1/3, but I definitely want to be able to use this to calibrate and use my sights. I'm hoping that by careful selection of scope & mount I can get pretty much full co-witness.

* Probably under $100. I'm willing to pay what I need to, but don't want to pay more than needed. Not interested in wasting money, either by paying for more than I need, or buying something I won't be happy with and will have to replace. I want to just buy one (1).

That's what I /think/ I need. Feel free to correct me, or add other specs to my list.

Nothing? Really?

I have a Bushnell -- don't remember the model number, and I'm at work -- it will switch from red to green and will also switch from small dot, small dot in a circle, large dot and small cross hair. Mounted with quick release rings.

I have not had the opportunity to shoot it much, but I prefer the red during daylight and green in low light. I know the red should not affect night vision as much as green, but even on the lowest setting, the red seems glaring at night and the green not.

If you don't have to have the green option, check out the Primary Arms multi reticle dot.

I've been looking at the Primary Arms PAM3M as you suggest. From other reviews, the 2 MOA dot is a good compromise with old eyes, and I love the multi-reticles. Only thing is not having green, and the only reason I thought I wanted green is the recommendation of people who say it's better in sunlight, which is what I'm going to be shooting in (at targets).

I see it has a 30 mm tube. Do you know if it will work with McStar MARFQ QD mount? I ended up with one when I decided to use the PEPR on my scope. I see PA sells reasonably priced mounts, but not are QR, I think.

Green is overated IMO. I use my red micro dots all day long at settings 5-8 out of 11.

Post a pic or link to you're mount and I can give my opinion. I'm not familiar with the model you mentioned.

FYI, I don't have the PAM3M, I'm just a happy PA customer and I love my micro's. I've heard lots of good things about that optic.

Here's a link: NcStar AR15 QR Cantilever Scope Mount (MARCQ)

It's for 30 mm scopes, the rear (non-cantilevered) ring can be removed, and ring is 0.7" long.

I see PA makes a nice cantilever mount, only $10 extra, but it's not QD, which I would prefer.

I prefer the green dot on my vortex strikefire but even in bright sunlight I can see the red dot just fine. It has 10 brightness settings and I rarely turn it to the brightest setting. Its a really good red dot optic, its not a multi-reticle but it works great especially if you have other AR's to mount it on. Its rated for .375 h&h mag so it holds a zero just fine on a .22lr. If you get the high mount for it you can co-witness the buis but it doesn't come with a QR mount.

It's not going to work. There's no place on that optic for the second ring to attach. You would need something like this. American Defense MFG, LLC | Browse | Aimpoint Mounts | High Profile Aimpoint Mount

It's a little spendy, but keep in mind a good QD mount isn't cheap if you want it to work the way a QD mount is supposed to. I'm sure there's another good option for a mount that costs less, but I don't know of any.

As I mentioned above, the second (rear) ring can be removed, and only the front (cantilevered) ring used. It is also the same height as the AD-68 mount you refer to, which ends up about 0.1" above the iron sight sighting line (folding sights are a bit lower, I think, than standard ones).

I thought you planned on just leaving the top of the rear ring off, but know I see that the whole thing can be removed. That's a pretty nifty little mount and I can't see why it wouldn't work. does it return to zero and stay tight? I might have to pick one up for my 10-22. I'm not a fan of NcStar anything, but it could be an exception.

I originally ordered the Burris AR-PEPR QD mount, which I like better, but is fairly expensive ($100) and after ordering, I found out it wouldn't fit the BSA 4-14x44 scope I'd ordered, so I ordered my second choice, this NcStar mount. After getting the Burris, I found that a little Dremel work made the mount fit, so I'm using it. That leaves me with the NcStar mount. It only has a single long locking lever, rather than the two on the Burris, but seems to lock pretty well, and is long enough (I think) to return to zero okay. Especially for a red-dot (as opposed to a high power scope).

If I get the PA PAM3M, I'll probably order the cantilever mount I can get with it for the extra $10, even though it's not QA. That way, I can at least use it, if the NcStar doesn't work out well (although I really think it will).

Can PA scopes be purchased anywhere other than PA (i.e. at a discount)?

You might consider the TruGlo Dual Red/Green reflex and tube model red dots. I have both, one for my AR15-22 for speed shooting events and one for my 597 VTR as backup if needed.

There's quite a range (price and styles) of them. Which do you recommend? Do any have multiple reticles? I think that's more important to me than the green.

Thanks all. I've ordered the Primary Arms PAM3M with high cantilevered riser. I will either use that riser, or the NcStar QD which I have.

You'll like the PA M3... I have one with the cantilever riser on my 15A and I'm very satisfied with it!

I have a utg one. Cost about 60$ at LGS. Works good for what I use it for. I also got a 3/4" riser and co-witnessed it with stock iron sights.

You'll be pleasantly surprised with that red dot. Also, Marshall is excellent with customer service if by chance you do have a problem.

Agree about Marshall. He and the guys at PA are top notch on the service end and the products are solid.

Yes the reflex one has 4 reticles.
