I totally recommend the Apex Gator free float hand guard for the M&P10. Along with a DPMS Barrel nut. I bought the short Carbine length Apex Hand Guard because I wanted to be able to use the Factory Gas Block, it is lighter weight and the short one would be more rigid and less likely to give when using a bipod. With the Apex Hand guard you DO NOT have to replace the dust cover rod with a longer one as you would need in most other free floating hand guards because the Apex hand guard covers the whole barrel nut just as the Delta ring did. I bought a new DPMS Barrel nut because I didn't want to just cut the delta ring off and wanted the option to restore the rifle to the original state if needed. The Apex Hand guard was easy to install and is very sturdy with a lot of grip for hands or gloves.
