Smith & Wesson M&P15 Sport II Semi-Auto Rifle

[JesseX]

Regarding the Smith & Wesson M&P15 Sport II Semi-Auto Rifle. How thick is the barrel? .625? .750? .936?

Is the metal 4140 of 4150?

Also, it nearly appears to be non-free-floating because the barrel sticks out so far from the handrail. Am I missing something?

Thanks
