I own both the m400 and m&p 15 sport. Both have functioned flawlessly. Do some more research (youtube esp),specifications (barrel twist, furniture, etc.) and decide for yourself. I bought the m400 first so that tells you my opinion.

Actually that leaves me a little confused. Do you think the m400 is better, and that's why you bought it first? Or was the m400 that you purchased first unsatisfactory and that's why you bought an M&P15?
In any case, the sport and the T are different guns, and between the m400 and the M&P15T you can't go wrong.
I just found in the M400 the handguard is too short, the 15T has better rail saying that, anyone has install a Troy Battlerail Delta or Charlie on any of them?
I want to keep my front post and make no alterations...
I saw your same question over at the sig sauer form (in three different threads). *edit* those rail/hand guard systems look promising. I might have to check them out some more.
