Quick question, I cant find this info on the interwebs of doom. I was wondering what the Barrel Diameter of the M&P ORC barrel is? I am looking to go free float and need a low pro gas block to fit under one. I'm fairly sure its a standard size but I'm still waiting for the nics to come back and want to have the correct parts before I even get the Rifle home.

 

Thanks ahead of time.

    Gas block sizes are .625, .750, and .936.   A guess would say .750, because it does not look like a lightweight .625  or bull barrel .936.  To be sure maybe you could ask over at the S&W forum.  I am sure they would have your answer.

    I don't even have to look, its definitely .750 The M&P ORC comes with an industry standard government profile barrel.
