Anything that feels good in your shoulder and provides a solid cheek weld will work.
I have a lower setup with a match trigger and a Magpul PRS stock. It is very solid but is also heavy, and rarely gets used.
The Magpul MOE carbine stock is solid and lightweight.
The newer MOE SL stock is nice. It's a good mix of simple like the MOE carbine but more rigid.
Most of the time I run a Magpul MOE carbine stock and standard buffers with midlength gas systems. I do have a Magpul MOE SL carbine stock on my SR15 and I like it.
