Very Happy with my 16" FAXON 6.5Grendel build.

28.5 XBR is also the sweet spot for my 16" Odin barrel.

Tech guy at Odin Works, Aaron also uses the 16" Grendel fornhis personal gun and 28.5 XBR was his sweet spot too... recurring theme it seems..

Just ordered one of these barrels.

I am going to take apart a 20" 5.56 I rarely shoot, and put the barrel on that. Eventually I will spruce it up with some more goodies.
