I heard and read that the FCG in M&P 15-22 is Mil-Spec FCG just like any other AR15 Mil-Spec FCG. Has anyone upgraded their FCG in theirs? What did you replaced with? Any issues?
I did when I had mine. I put a Timney in it. Took it out and put the factory one back in when I sold it. Upgrades the same as a regular AR.
