I'm making my own 6.5 Grendel AR-15, I'm buying a 18" Satern Stainless Steel barrel with flash hider threads on the end. I've been looking on line for some flash hiders that are stainless steel in 6.5 but can't find any... anyone know where to look? If yall want more details about the build just ask, will be glad to share what I'll be using.
