Excellent! They are super fun to shoot.
The next question is iron sights or optics?
You can have a lot of fun with iron sights. However, I prefer optics. If you have young eyes, a red dot makes shooting more fun. Place the dot on the target and press the trigger. If you're like me and could use a little magnification, there are some good scopes for not a whole lot of money.
Buying the gun without thinking about the sighting system is a mistake. So, think about it.
Now, I'm going to talk about optics for a moment and it's going to hurt so, sit down...good optics will cost as much or more than the gun. This is a fact. Don't panic though, this is not the end. Decent optics can be had for less.
Some examples:
The Trijicon MRO or Aimpoint H1 are top of the line red dots. The MRO is about $500 and the H1 is about $700.

A company called Primary Arms makes a very decent red dot called the Advanced Microdot for about $180.
For magnified optics my favorite is the Trijicon ACOG which is a fixed power scope. It will run about $1,200-$1,400 depending on model.


For variable scopes there is the very nice Vortex Razor Gen II 1-6x24 for about $2K or the Nightforce ATACR[emoji769] 1-8x24 for about $1,720.



You were sitting down, right? There's also the Leatherwood Hi-Lux CMR 1-4x 24 for about $330 which is a really decent scope for that price.
Then there's the iron sights. The M&P Sport II comes with a flip up rear and fixed front sight post. This is by far the least expensive way to go. The issue comes when you decide you want to add an optic. That front post can get in the way.
As you can see there's a lot to think about when it comes to sighting systems. Just be sure to think about it.
Head spinning yet?
My recommendation? If I were starting over with what I know now, I would start with the M&P Sport II OR and put the Primary Arms Advanced Microdot on it. This combination is a nice rifle and really decent optic for less than $850 out the door.
