Ok, enough people have asked and I found someone with a sizable number of them in-stock and ready to ship.
Call Pete @ 603-770-2281. It's Legal Transfers. You can check out the website @ www.ar15sales.com
This guy has been around a long time and is the longest running and most respected dealer on ar15.com as well.
Much better than the 120$ (plus shipping) that other dealers online are charging for them.
Enjoy.
p.s. If you're trying to find LPK's let me know. I haven't seen RRA LPK's back on the market yet but other brands are available for lower than RRA prices.
EDIT: You CAN order online, click on "AR-15 Parts" from the sites top menubar are use this link: http://ar15sa.fatcow.com/store/miscparts.html

I think my RRA already has some sort of upgraded trigger.
Most RRA AR's already have the 2 stage match trigger. That's what makes it a nice bargain unless you are a purist and think that the trigger is not up to the rigorous standards of USGI triggers. Personally, all but 2 of my AR's have the RRA 2 stage trigger. My 9mm AR can't because of the unmodified bolt carrier and my SPR because it has a Jard precision trigger.

what is the benefit of the two stage?

Quicker double-taps, shorter pull on 2nd stage, and on some 2-stage (don't know if RRA is) are adjustable weight of pull for 1st and 2nd stages.
There are some lower receivers that have a spring access port that allows you to make a standard USGI trigger into an adjustable single stage trigger. Superior Arms lowers have that option.

Specific to an AR, it offers a much more controlable trigger for precision work if your budget doesn't include a high end single stage trigger.
The design of USGI single stage triggers for semi-auto AR's involves having a "robust" disconnector that prevents the hammer from re-releasing without the trigger being reset. Usually, the reset is a long one, so you are working against the tension of the hammer and trigger springs, the friction of the sear, and the positive angle of the sear for quite a long ways by design. That generally means a heavy trigger pull that makes for poor sear release predictability.
A well fitted (slightly positive or neutral sear angle) and polished single stage can be crisp and smooth, but you need to work hard at creating it and ones that are pre-fitted are expensive and not recommended for LE or military duty (except for snipers).
When the hammer is cocked on RRA's 2 stage trigger, it is held by the trigger sear and secondly by a hook on the disconnector. When you press the trigger, the first stage is the tension from the disconnector spring and trigger spring as the disconnector hook moves out of the way from the hammer however, the trigger/hammer sear remain unchanged. The second stage is a much more firm release of the trigger/hammer sear. They can by design make the trigger/hammer sear much shorter in travel due to the 1st stage "safety" which makes it easy for precision shooting.

Good info Phil!
Actually now that I sit here with my cup of coffee this morning, I realized that I had it backwards, the hook grabs the hammer once the disconnector is engaged ie firing and holding the trigger down. When you release the trigger, the hook releases the hammer into the sear. The first stage is the pressure of the hook not able to grab the hammer any longer and thus just pressing against it.
so whay are you trying to confuse us...
