So I just picked up my M&P, same fit and finish issue as the original poster. I got mine from a different vender. Judging by the speed they slapped my trigger lock on and resealed the box this is a known issue. Buddy kept his hand around the charging handle the whole time the box was open. I certainly hope the venders aren't intentionally passing on ill fitting hardware so we can deal with trying to get warranty
Which vendor?
A gap is not a gap is not a gap. It's perfectly normal for there to be a slight gap there (like the horizontal gap between the upper and lower). The tolerance for that radius in front of the receiver extension in the blueprint of the lower receiver is +.006 and -.000 from the center of the front pivot pin, I don't have the upper blueprint on hand but I assume there is an allowable tolerance too, probably +.000 to -.something.My son just got one and it also has a gap. He says "So, what?". It's a budget rifle and is an excellent deal. After all, it's an AR, so it should work just fine. I think, he's right.

Would that be the same vendor?
Yeah there are some major differences between yours and mine. I see that yours also has white and red text on the side, which is not the case on mine or on the rifles featured on the official website. I honestly think that thing might be a knockoff. Unless I'm off and you modded that yourself.
Here's a photo of mine: https://i.imgur.com/2s1qJGx.png and here's the official site: https://www.smith-wesson.com/firearms/mp-15-sport-ii. I also checked some YouTube vids like hickock45's, and all their Sport 2s are like mine with no color on the lower apart from the M&P logo in white.
That rifle was machined and assembled all kinds of wrong ways...
