I have 3 rifles with Magpul fixed stocks because they work and I like the way they look. Magpul is plentiful, and a pretty decent value for the functionality you get, especially in the MOE line.
I also have a VLTOR EMod stock that I like quite a bit. There are a ton of stocks out there, and most of them are good. RRA makes good ones. BCM makes good ones. Hogue makes good ones. Daniel Defense, Ergo, and a bunch of others make great stocks. Find one you like the look of, make sure it's compatible with your buffer tube, and go to town.
