For a precision AR, your two best options for a "fixed" stock are likely to be the PRS, or a standard A2/A1.
I run a PRS on one of my rigs, and love it. It is, however, heavy, and large. More suited to use on a rifle that isn't going to be hauled around on a sling for extended periods. That being said, I frequently do so and it's not all
that bad. I love the adjustments, but have two friends who bottom out the cheek riser and length of pull extension, which makes it basically an A1 configuration. If you have a chance to shoot a rifle with one on it, check to see if the adjustability is something you want/need. At over $200, it's an expensive stock for a "cool look" if you don't use the enhancements. Also, if you plan to use a rear monopod, it offers you that option as well with the rear pic rail. Other great benefit is that it balances a "front heavy" rifle really well.
The A1 or A2 (depending on your desired length of pull, is relatively inexpensive and sturdy as hell (as I'm assuming you already know based on your SN
S/F). Keeps it light and simple if that's important to you.
One other option that comes to mind would be the Magpul UBR - similar cheekweld/rigidity to a fixed stock, but offers the length of pull adjustment of a 7 position.
Hope it helps - can't really go wrong with any of them.
