Using the Red Lion foreend it is very difficult to get any red dot on an AR riser to co-witness. The rail is just too high in relation to the factory sights. This has been the one big issue since the Red Lion foreend was introduced. I wish I had an easy answer for you, but I haven't had access to an RL foreend to tinker. You might try spending some time looking at the latter half of the Sub Porn Pic thread to see what members have done to make theirs work. Posters are encouraged to list parts and descriptions in there with their pictures.

I do know that some have mounted the Keltec rail and used the red lion hardware to attach. The Keltec rail is lower (thinner). But really, your best bet is just to call Red Lion. They answer the phone and I'm sure they can give you the MOST accurate information to help you.
It's too high with a spacer, and too low without. I ordered a couple of different Trijicon mounting brackets to see if I can get in the middle. I should be able to update in a few days, or first of next week, when I receive the brackets.

OK. But also read the red lion thread in the Stickys(?) Section above. A call to Red Lion. And my suggestion of the Keltec rail.
I don't own the forend. But look through the Porn and Scope Mount threads. Unless its been deleted or lost, someone at ktog has done the same set up you have/want. At least on a gen1.

Below are some Red Dot options for cowitnessing, I'm not familiar with Spyder and the only Vortex I know of that can be cowitnessed is the Strikefire (more on that below).
The absolute cowitness height is 1.1" from the top of the picatinny rail to the center line of the optic.
Here is a link to the Burris Xtreme ring that will cowitness a 30mm tube red dot like an Aimpoint M series or Pro or the Vortex Strikefire, for absolute cowitness you would want Burris part # 420163 which is the Medium Height. If you are looking at other rings and the rings give the distance from the top of the picatinny rail to the bottom of the 30mm ring then 1/2" is what that distance should be for an absolute cowitness as 30mm is approx 1.2" which divided by 2 is .6" and .6" plus 1/2" is 1.1". :

The Aimpoint Pro will place the red dot approximately .100" above absolute cowitness (between an absolute cowitness and a lower 3rd cowitness) with its supplied QRP2 mount (optional supplied spacer removed). The QRP2 mount comes with it so you wouldn't need the Burris ring above unless you wanted an absolute cowitness.

The most common setup is the Bushnell TRS25 and a 1/2" riser which gives you an absolute cowitness:
Bushnell TRS25 (the 1/2 Riser doesn't come with the TRS25, the Yankee Hill one is most popular and its listed below):

So, thanks for everyone who replied to the post! I appreciate the input, since I am fairly new to the sub 2000. In order to cowitness, I ended up using the American Defense Mfg. AD-RMR-LH STD. It has a quick release, but it's still a little low for my taste. At least for now, I'm happy with this solution. I attached a few pics of the setup.

I was exploring this myself, with my new Gen2 (I had a Gen1 a few years ago) with a few tubes I have -- example the Vortex Sparc II, a very fine piece of equipment for its build value, and works great on my MechTech.
However, when I mount it on my S2k, I have quite a bit of viewing obstruction with the stock sights on the Gen2 unit, and I have full co-witness of the optic.
I'm not keen on the 45* offset, even if the weapon folds and locks, the protrusion for many tubes still makes it a bit clunky for easy and slim storage.
For me, I will stick with the irons, and leave my RDS for the MechTech and other equipment better suited for them.

Thanks for the welcome. I am looking at some other mounting options I will experiment with next time I head out for a shoot. I'm used to full co-witnessing, but I think I will raise the optic up and employ a QD bracket that I should receive tomorrow -- that will let me set on the bottom pic-rail and still let me fold the unit completely.

Looks like there are some additional choices now for RD mounts
Here's the one I use:
Interesting that both originate from Midwest Industries.

I ordered the new MI T2 mount as well ( I really need to stop watching gun porn), even though I have a fully functioning MI one o'clock mount right now. Will be a lot nicer to shoot without having to tilt the rifle though.
On a sidenote, I recently removed the handguard from my Gen 2. I put small strips of foil tape on the ribs that ride on the barrel inside the handguard. Is now a much snugger fit and it does not move at all. Before, despite tightening of the screws, I could always get it to move a small amount fore, aft and sideways.
