Just got mine down here in Evansville at Red Ghost. Mounted a Primary Arms red dot but haven't had a chance to shoot it yet. Total AR newb so I don't really feel qualified to judge against entry AR's. Seems built like a quality firearm so far and I've heard good things around these forums so that was enough for me to pull the trigger, so to speak.
Just got one a little while ago. Well worth the money and being an AR newb myself couldn't be happier. The sights should pretty much be spot on from the factory. It will need a little bit of cleaning and lubing before you start shooting.
I have one as well, and it is a decent rifle for sure. It has a carbine-length gas system in a 16" barrel, which is OK and it has a 1:9 twist. My other AR has as mid-length gas system with a 16" barrel which I like better for recoil management.
I am pretty surprised at how well the M&P15 Sport II shoots however. It is my go-to self-defense and CQB gun, and I am running a Vortex red dot on it. I love mine!
