I really like the fluted barrel too. I am upgrading my M&P. There were some great sales yesterday. Although I really like my quad rail, I’m getting rid of it to cut down on weight. I’m mounting an ATLAS S One free floating handguard. Hopefully it turns out as good as yours.

For optics i’m Running a vortex viper 1-6 pst gen 2 (best bang for the buck). I’m sold on/in love with vortex but if you’re wanting to save some money the Primary Arms 1-6X is awesome too. I think it’s the best entry level variable optic out there. Pew pew Tactical has some good reviews on both of these.

We’re finishing my wife’s ar next week and we’re planning on putting the vortex strike fire prism on it.
