That is our 9" carbon fiber Takedown barrel and our XB-1 barrel comp in the MWI 8" handguard and chassis. On the rear is a Mil spec buffer tube, Strike Industries castle nut, Magpul CTR butt stock, Mil spec cheapo pistol grip all topped off with the brilliant Trijicon MRO optic. If you nix the XB-1 comp and go with a 12.5" barrel you are still N/R but are also legal to use it to hunt.
