I know this may sound trivial, but is there any real advantage to having a mil-spec buffer setup as compared to a commercial type? I am new to working with AR's as far as building/modifying them. I have a Double Star DS-4 and a Colt 6920, but i will probably leave the Colt as-is. Also, if i switch out the buffer tube assembly on the Double Star, can i just unscrew the commercial tube and screw the mil-spec one in, or is it a different thred size than what is on my reciever?

I didnt want to invest in a mil-spec assembly, only not to be able to use it.

I'd stick will milspec for parts compatibility
To be honest though I've used a good handful of different buffer tubes and there is a difference in quality and how smooth it feels when you're cycling the action. The best I have are vltor tubes with decent springs, noting some springs also cycle smoother than others I believe the brownells.com 'stock completion kits' use vltor items |
