I really like my M&P 10. The ambi controls are nice. I found a UTG aluminum rail for it and free floated the barrel. Trigger upgrade and new stock. It's been 100% reliable and I like it. I do wish there were more after market parts. I put a CNC 4lb trigger in it which I had to mod due to the ambi bolt release. I just used a cutting wheel on the Dremel and cut a notch out of it. Only a cosmetic adjustment. Pmags work great and I did replace the FH thing because it's odd looking. It has holes like a brake and slits like an FH but whatever it's just too big. I put an AAC brake on it in case I get a can, which I want to do, just been lazy and poor.
