I impulsively bought 2 complete Aero lowers with stocks, I've had a few ar15's but never a 308 ar. Are there any brands of complete uppers that will fit on these lowers? I'm going to start with just 1 and I think I'd like to go with a 20" barrel hunting/target type gun, and it looks like aero only sells 16" complete uppers. This is all new to me and with all my reading it looks like I'm better off buying aero uppers and building the guns off of that, I'm sure I can do it but there's a lot of info to take in doing that and want to make sure I do it right. So if you can tell me there's no other brand of complete upper that I can throw on these lowers then I'll start researching more on how to put an upper together and figure out what I need to buy.

Theoretically, any DPMS style upper will work.
